After installing a route to the kernel, user space receives an
acknowledgment, which means the route was installed in the kernel, but not
necessarily in hardware.
The asynchronous nature of route installation in hardware can lead to a
routing daemon advertising a route before it was actually installed in
hardware. This can result in packet loss or mis-routed packets until the
route is installed in hardware.
To avoid such cases, previous patch set added the ability to emit
RTM_NEWROUTE notifications whenever RTM_F_OFFLOAD/RTM_F_TRAP flags
are changed, this behavior is controlled by sysctl.
With the above mentioned behavior, it is possible to know from user-space
if the route was offloaded, but if the offload fails there is no indication
to user-space. Following a failure, a routing daemon will wait indefinitely
for a notification that will never come.
This patch adds an "offload_failed" indication to IPv6 routes, so that
users will have better visibility into the offload process.
'struct fib6_info' is extended with new field that indicates if route
offload failed. Note that the new field is added using unused bit and
therefore there is no need to increase struct size.

mlx5-updates-2021-02-04
Vlad Buslov says:
=================
Implement support for VF tunneling
Abstract
Currently, mlx5 only supports configuration with tunnel endpoint IP address on
uplink representor. Remove implicit and explicit assumptions of tunnel always
being terminated on uplink and implement necessary infrastructure for
configuring tunnels on VF representors and updating rules on such tunnels
according to routing changes.
SW TC model
From TC perspective VF tunnel configuration requires two rules in both
directions:
TX rules
1. Rule that redirects packets from UL to VF rep that has the tunnel
endpoint IP address:

HW offloads model
For hardware offload the goal is to mach packet on both rules without exposing
it to software on tunnel endpoint VF. In order to achieve this for tx, TC
implementation marks encap rules with tunnel endpoint on mlx5 VF of same eswitch
with MLX5_ESW_DEST_CHAIN_WITH_SRC_PORT_CHANGE flag and adds header modification
rule to overwrite packet source port to the value of tunnel VF. Eswitch code is
modified to recirculate such packets after source port value is changed, which
allows second tx rules to match.
For rx path indirect table infrastructure is used to allow fully processing VF
tunnel traffic in hardware. To implement such pipeline driver needs to program
the hardware after matching on UL rule to overwrite source vport from UL to
tunnel VF and recirculate the packet to the root table to allow matching on the
rule installed on tunnel VF. For this, indirect table matches all encapsulated
traffic by tunnel parameters and all other IP traffic is sent to tunnel VF by
the miss rule. Such configuration will cause packet to appear on VF representor
instead of VF itself if packet has been matches by indirect table rule based on
tunnel parameters but missed on second rule (after recirculation). Handle such
case by marking packets processed by indirect table with special 0xFFF value in
reg_c1 and extending slow table with additional flow group that matches on
reg_c0 (source port value set by indirect tables) and reg_c1 (special 0xFFF
mark). When creating offloads fdb tables, install one rule per VF vport to match
on recirculated miss packets and redirect them to appropriate VF vport.
Routing events
In order to support routing changes and migration of tunnel device between
different endpoint VFs, implement routing infrastructure and update it with FIB
events. Routing entry table is introduced to mlx5 TC. Every rx and tx VF tunnel
rule is attached to a routing entry, which is shared for rules of same tunnel.
On FIB event the work is scheduled to delete/recreate all rules of affected
tunnel.
Note: only vxlan tunnel type is supported by this series.

100GbE Intel Wired LAN Driver Updates 2021-02-05
This series contains updates to ice driver only.
Jake adds adds reporting of timeout length during devlink flash and
implements support to report devlink info regarding the version of
firmware that is stored (downloaded) to the device, but is not yet active.
ice_devlink_info_get will report "stored" versions when there is no
pending flash update. Version info includes the UNDI Option ROM, the
Netlist module, and the fw.bundle_id.
Gustavo A. R. Silva replaces a one-element array to flexible-array
member.
Bruce utilizes flex_array_size() helper and removes dead code on a check
for a condition that can't occur.
v2:
* removed security revision implementation, and re-ordered patches to
account for this removal
* squashed patches implementing ice_read_flash_module to avoid patches
refactoring the implementation of a previous patch in the series
* modify ice_devlink_info_get to always report "stored" versions instead
of only reporting them when a pending flash update is ready.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
ice: remove dead code
ice: use flex_array_size where possible
ice: Replace one-element array with flexible-array member
ice: display stored UNDI firmware version via devlink info
ice: display stored netlist versions via devlink info
ice: display some stored NVM versions via devlink info
ice: introduce function for reading from flash modules
ice: cache NVM module bank information
ice: introduce context struct for info report
ice: create flash_info structure and separate NVM version
ice: report timeout length for erasing during devlink flash

It's possible that the length passed to ipa_header_size_encoded()
is larger than what can be represented by the HDR_LEN field alone
(starting with IPA v4.5). If we attempted that, u32_encode_bits()
would trigger a build-time error.
Avoid this problem by masking off high-order bits of the value
encoded as the lower portion of the header length.
The same sort of problem exists in ipa_metadata_offset_encoded(),
so implement the same fix there.

An event ring's state only needs to be known when it is allocated,
reset, or deallocated. We check an event ring's state both before
and after performing an event ring control command that changes
its state. These are only issued at startup and shutdown, so there
is very little value in caching the state.
Stop recording a copy of the channel's last known state, and instead
fetch the true state from hardware whenever it's needed. In such
cases, *do* record the state in a local variable, in case an error
message reports it (so the value reported is the value seen).

The ocelot switch has been supporting LAG offload since its initial

At present there is an issue when ocelot is offloading a bonding
interface, but one of the links of the physical ports goes down. Traffic
keeps being hashed towards that destination, and of course gets dropped
on egress.
Monitor the netdev notifier events emitted by the bonding driver for
changes in the physical state of lower interfaces, to determine which
ports are active and which ones are no longer.
Then extend ocelot_get_bond_mask to return either the configured bonding
interfaces, or the active ones, depending on a boolean argument. The
code that does rebalancing only needs to do so among the active ports,
whereas the bridge forwarding mask and the logical port IDs still need
to look at the permanently bonded ports.

We can now simplify the implementation by always using ocelot_get_bond_mask
to look up the other ports that are offloading the same bonding interface
as us.
In ocelot_set_aggr_pgids, the code had a way to uniquely iterate through
LAGs. We need to achieve the same behavior by marking each LAG as visited,
which we do now by using a temporary 32-bit "visited" bitmask. This is
ok and we do not need dynamic memory allocation, because we know that
this switch architecture will not have more than 32 ports (the PGID port
masks are 32-bit anyway).

The setup of logical port IDs is done in two places: from the inconclusively
named ocelot_setup_lag and from ocelot_port_lag_leave, a function that
also calls ocelot_setup_lag (which apparently does an incomplete setup
of the LAG).
To improve this situation, we can rename ocelot_setup_lag into
ocelot_setup_logical_port_ids, and drop the "lag" argument. It will now
set up the logical port IDs of all switch ports, which may be just
slightly more inefficient but more maintainable.

The index of the LAG is equal to the logical port ID that all the
physical port members have, which is further equal to the index of the
first physical port that is a member of the LAG.
The code gets a bit carried away with logic like this:
if (a == b)
c = a;
else
c = b;
which can be simplified, of course, into:
c = b;
(with a being port, b being lp, c being lag)
This further makes the "lp" variable redundant, since we can use "lag"
everywhere where "lp" (logical port) was used. So instead of a "c = b"
assignment, we can do a complete deletion of b. Only one comment here:
if (bond_mask) {
lp = __ffs(bond_mask);
ocelot->lags[lp] = 0;
}
lp was clobbered before, because it was used as a temporary variable to
hold the new smallest port ID from the bond. Now that we don't have "lp"
any longer, we'll just avoid the temporary variable and zeroize the
bonding mask directly.

Since this code should be called from pure switchdev as well as from
DSA, we must find a way to determine the bonding mask not by looking
directly at the net_device lowers of the bonding interface, since those
could have different private structures.
We keep a pointer to the bonding upper interface, if present, in struct
ocelot_port. Then the bonding mask becomes the bitwise OR of all ports
that have the same bonding upper interface. This adds a duplication of
functionality with the current "lags" array, but the duplication will be
short-lived, since further patches will remove the latter completely.

Since switchdev/DSA exposes network interfaces that fulfill many of the
same user space expectations that dedicated NICs do, it makes sense to
not deny bonding interfaces with a bonding policy that we cannot offload,

Make ocelot's net device event handler more streamlined by structuring
it in a similar way with others. The inspiration here was
dsa_slave_netdevice_event.

ocelot_netdevice_changeupper
ocelot_netdevice_port_event treats a single event, NETDEV_CHANGEUPPER.
So we can remove the check for the type of event, and rename the
function to be more suggestive, since there already is a function with a
very similar name of ocelot_netdevice_event.

The max qset number is a fixed value now and it is defined by a macro.
In order to support other value in different kinds of device, it is
better to use specification queried from firmware to replace macro.

Since the newer hardware may supports different frame size,
so add support to obtain the capability from the firmware
instead of the fixed value.

When update the TC info for NIC, there are some differences
between PF and VF. Currently, four "vport->vport_id" are
used to distinguish PF or VF. So merge them into one to
improve readability and maintainability of code.

As RSS indirection table size may be different in different
hardware. Instead of using macro, this value is better to use
device specification which querying from firmware.
BTW, RSS indirection table should be allocated by the queried
size instead the static array.
.get_rss_indir_size in struct hnae3_ae_ops is not used now,
so remove it as well.

Add support for backplane link mode, which is, according to discussions
with NXP earlier in the year, is a mode where the OS (Linux) is able to
manage the PCS and Serdes itself.
This commit prepares the ground work for allowing 1G fiber connections
to be used with DPAA2 on the SolidRun CEX7 platforms.

Now that pcs-lynx supports 1000BASE-X, add support for this interface
mode to dpaa2-mac. pcs-lynx can be switched at runtime between SGMII
and 1000BASE-X mode, so allow dpaa2-mac to switch between these as
well.

This converts the driver to use the new tasklet API introduced in
commit 12cc923f1ccc ("tasklet: Introduce new initialization API")
The new API changes the argument passed to callback functions,
but fortunately it is unused so it is straight forward to use
DECLARE_TASKLET rather than DECLARE_TASLKLET_OLD.
