Saeed Mahameed says:
====================
This patch series contains various fixes, additions and improvements to
mlx5 software steering.
Patch 1:
adds support for REMOVE_HEADER packet reformat - a new reformat type
that is supported starting with ConnectX-6 DX, and allows removing an
arbitrary size packet segment at a selected position.
Patches 2 and 3:
add support for VLAN pop on TX and VLAN push on RX flows.
Patch 4:
enables retransmission mechanism for the SW Steering RC QP.
Patch 5:
does some improvements to error flow in building STE array and adds
a more informative printout of an invalid actions sequence.
Patch 6:
improves error flow on SW Steering QP error.
Patch 7:
reduces the log level of a message that is printed when a table is
connected to a lower/same level destination table, as this case proves to
be not as rare as it was in the past.
Patch 8:
adds missing support for matching on IPv6 flow label for devices
older than ConnectX-6 DX.
Patch 9:
replaces uintN_t types with kernel-style types.
Patch 10:
allows for using the right API for updating flow tables - if it is
a FW-owned table, then FW API will be used.
Patch 11:
adds support for 'ignore_flow_level' on multi-destination flow
tables that are created by SW Steering.
Patch 12:
optimizes FDB RX steering rule by skipping matching on source port,
as the source port for all incoming packets equals to wire.
Patch 13:
is a small code refactoring - it merges several DR_STE_SIZE enums
into a single enum.
Patch 14:
does some additional refactoring and removes HW-specific STE type
from NIC domain.
Patch 15:
removes rehash ctrl struct from dr_htbl struct and saves some memory.
Patch 16:
does a more significant improvement in terms of memory consumption
and was able to save about 1.6 Gb for 8M rules.
Patch 17:
adds support for update FTE, which is needed for cases where there
are multiple rules with the same match.

Add the support for update FTE, which is needed for cases where there are
multiple rules with the same match. In such case fs_core will merge the
actions and call update FTE to update current FTE. Since we don't want to
disrupt the traffic, we will add the new duplicate rule, and only then
remove the old duplicate rule.

To track each STE of the rule a rule member was allocated, each
member would point to one STE. This means that we would allocate
40B (rule member) * number of STEs per rule.
To reduce this per rule allocation we use the STE tree pointers
for next_htbl and pointing STE to navigate the tree, this allows
us to keep only the pointer to the last STE of rule (always unique).
From the last rule STE we are able to traverse and rebuild all of
the STEs that construct the rule.
In our testing with 8M rules, each consisting of 7 STES, we were able
to reduce 1.6GB of memory.

The FDB RX pipe is connected to the wire and the source port for all
incoming packets equals to wire, single uplink port per PF, this means
there is no point of matching on the source port in such case.

Note that in such case we clean both source_eswitch_owner_vhca_id and

which is eventually created by FW. In such case, this FW table should

When handling FIB_EVENT_ENTRY_REPLACE event for a new multipath route,
lag activation can be missed if a stale (struct lag_mp)->mfi pointer
exists, which was associated with an older multipath route that had been
removed.
Normally, when a route is removed, it triggers mlx5_lag_fib_event(),
which handles FIB_EVENT_ENTRY_DEL and clears mfi pointer. But, if
mlx5_lag_check_prereq() condition isn't met, for example when eswitch is
in legacy mode, the fib event is skipped and mfi pointer becomes stale.
Fix by resetting mfi pointer to NULL in mlx5_deactivate_lag().

Currently, when query PFC configuration by dcbtool, driver will return
PFC enable status based on TC. As all priorities are mapped to TC0 by
default, if TC0 is enabled, then all priorities mapped to TC0 will be
shown as enabled status when query PFC setting, even though some
priorities have never been set.
for example:
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off
$ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0

In order to separate the atomic needs of __dev_uc_sync()
and __dev_mc_sync() from the safe rx_mode handling, we need
to have the ndo handler manipulate the driver's filter list,
and later have the driver sync the filters to the firmware,
outside of the atomic context.
Here we put __dev_mc_sync() and __dev_uc_sync() back into the
ndo callback to give them their netif_addr_lock context and
have them update the driver's filter list, flagging changes
that should be made to the device filter list. Later, in the
rx_mode handler, we read those hints and sync up the device's
list as needed.
It is possible for multiple add/delete requests to come from
the stack before the rx_mode task processes the list, but the
handling of the sync status flag should keep everything sorted
correctly. For example, if a delete of an existing filter is
followed by another add before the rx_mode task is run, as can
happen when going in and out of a bond, the add will cancel
the delete and no actual changes will be sent to the device.
We also add a check in the watchdog to see if there are any
stray unsync'd filters, possibly left over from a filter
overflow and waiting to get sync'd after some other filter
gets removed to make room.
