With an increased number of VFs, it's possible to encounter the following
issue during reset.
iavf b8d4:00:02.0: Hardware reset detected
iavf b8d4:00:02.0: Reset never finished (0)
iavf b8d4:00:02.0: Reset task did not complete, VF disabled
Increase the reset complete wait count to allow for 128 VFs to complete
reset.

Commit 4ae4916b5643 ("i40e: fix 'Unknown bps' in dmesg for 2.5Gb/5Gb
speeds") added the ability for the PF to report 2.5 and 5Gb speeds,
however, the iavf driver does not recognize those speeds as the values were
not added there. Add the proper enums and values so that iavf can properly
deal with those speeds.

adapter->link_speed has type enum virtchnl_link_speed but our comparisons
are against enum iavf_aq_link_speed. Though they are, currently, the same
values, change the comparison to the matching enum virtchnl_link_speed
since that may not always be the case.

Link speeds are communicated over virtchnl using an enum
virtchnl_link_speed. Currently, the highest link speed is 40Gbps which
leaves us unable to reflect some speeds that an ice VF is capable of.
This causes link speed to be misreported on the iavf driver.
Allow for communicating link speeds using Mbps so that the proper speed can
be reported for an ice VF. Moving away from the enum allows us to
communicate future speed changes without requiring a new enum to be added.
In order to support communicating link speeds over virtchnl in Mbps the
following functionality was added:
- Added u32 link_speed_mbps in the iavf_adapter structure.
- Added the macro ADV_LINK_SUPPORT(_a) to determine if the VF
driver supports communicating link speeds in Mbps.
- Added the function iavf_get_vpe_link_status() to fill the
correct link_status in the event_data union based on the
ADV_LINK_SUPPORT(_a) macro.
- Added the function iavf_set_adapter_link_speed_from_vpe()
to determine whether or not to fill the u32 link_speed_mbps or
enum virtchnl_link_speed link_speed field in the iavf_adapter
structure based on the ADV_LINK_SUPPORT(_a) macro.
- Do not free vf_res in iavf_init_get_resources() as vf_res will be
accessed in iavf_get_link_ksettings(); memset to 0 instead. This
memory is subsequently freed in iavf_remove().

fdb nexthops are marked with a flag. For standalone nexthops, a flag was
added to the nh_info struct. For groups that flag was added to struct
nexthop when it should have been added to the group information. Fix
by removing the flag from the nexthop struct and adding a flag to nh_group
that mirrors nh_info and is really only a caching of the individual types.
Add a helper, nexthop_is_fdb, for use by the vxlan code and fixup the
internal code to use the flag from either nh_info or nh_group.

The netif_running() test looks at __LINK_STATE_START which
gets set before ndo_open() is called, there is a window of
time between that and when the queues are actually ready to
be run. If ionic_check_link_status() notices that the link is
up very soon after netif_running() becomes true, it might try
to run the queues before they are ready, causing all manner of
potential issues. Since the netdev->flags IFF_UP isn't set
until after ndo_open() returns, we can wait for that before
we allow ionic_check_link_status() to start the queues.
On the way back to close, __LINK_STATE_START is cleared before
calling ndo_stop(), and IFF_UP is cleared after. Both of
these need to be true in order to safely stop the queues
from ionic_check_link_status().

The dynamic key update for addr_list_lock still causes troubles,
for example the following race condition still exists:
CPU 0: CPU 1:
(RCU read lock) (RTNL lock)
dev_mc_seq_show() netdev_update_lockdep_key()
-> lockdep_unregister_key()
-> netif_addr_lock_bh()
because lockdep doesn't provide an API to update it atomically.
Therefore, we have to move it back to static keys and use subclass
for nest locking like before.
In commit 1a33e10e4a95 ("net: partially revert dynamic lockdep key
changes"), I already reverted most parts of commit ab92d68fc22f
("net: core: add generic lockdep keys").
This patch reverts the rest and also part of commit f3b0a18bb6cb
("net: remove unnecessary variables and callback"). After this
patch, addr_list_lock changes back to using static keys and
subclasses to satisfy lockdep. Thanks to dev->lower_level, we do
not have to change back to ->ndo_get_lock_subclass().
And hopefully this reduces some syzbot lockdep noises too.

Patch series "mm: consolidate definitions of page table accessors", v2.
The low level page table accessors (pXY_index(), pXY_offset()) are
duplicated across all architectures and sometimes more than once. For
instance, we have 31 definition of pgd_offset() for 25 supported
architectures.
Most of these definitions are actually identical and typically it boils
down to, e.g.
static inline unsigned long pmd_index(unsigned long address)
{
return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1);
}
static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
{
return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
}
These definitions can be shared among 90% of the arches provided
XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined.
For architectures that really need a custom version there is always
possibility to override the generic version with the usual ifdefs magic.
These patches introduce include/linux/pgtable.h that replaces
include/asm-generic/pgtable.h and add the definitions of the page table
accessors to the new header.
This patch (of 12):
The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the
functions involving page table manipulations, e.g. pte_alloc() and
pmd_alloc(). So, there is no point to explicitly include <asm/pgtable.h>
in the files that include <linux/mm.h>.
The include statements in such cases are remove with a simple loop:
for f in $(git grep -l "include <linux/mm.h>") ; do
sed -i -e '/include <asm\/pgtable.h>/ d' $f
done

While trying to use the lantiq_gswip driver on one of my boards I made
a mistake when specifying the phy-mode (because the out-of-tree driver
wants phy-mode "gmii" or "mii" for the internal PHYs). In this case the
following error is printed multiple times:
Unsupported interface: 3
While it gives at least a hint at what may be wrong it is not very user
friendly. Print the human readable phy-mode and also which port is
configured incorrectly (this hardware supports ports 0..6) to improve
the cases where someone made a mistake.

The driver registers three different types of thermal zones: For the
ASIC itself, for port modules and for gearboxes.
Currently, all three types use the same get_trend() callback which does
not work correctly for the ASIC thermal zone. The callback assumes that
the device data is of type 'struct mlxsw_thermal_module', whereas for
the ASIC thermal zone 'struct mlxsw_thermal' is passed as device data.
Fix this by using one get_trend() callback for the ASIC thermal zone and
another for the other two types.

When the PHY's strap register is read to determine if lane swapping is
needed the phy_read_mmd returns the value back into the ret variable.
If the call to read the strap fails the failed value is returned. If
the call to read the strap is successful then ret is possibly set to a
non-zero positive number. Without reseting the ret value to 0 this will
cause the parse DT function to return a failure.

Pull rdma updates from Jason Gunthorpe:
"A more active cycle than most of the recent past, with a few large,
long discussed works this time.
The RNBD block driver has been posted for nearly two years now, and
flowing through RDMA due to it also introducing a new ULP.
The removal of FMR has been a recurring discussion theme for a long
time.
And the usual smattering of features and bug fixes.
Summary:
- Various small driver bugs fixes in rxe, mlx5, hfi1, and efa
- Continuing driver cleanups in bnxt_re, hns
- Big cleanup of mlx5 QP creation flows
- More consistent use of src port and flow label when LAG is used and
a mlx5 implementation
- Additional set of cleanups for IB CM
- 'RNBD' network block driver and target. This is a network block
RDMA device specific to ionos's cloud environment. It brings strong
multipath and resiliency capabilities.
- Accelerated IPoIB for HFI1
- QP/WQ/SRQ ioctl migration for uverbs, and support for multiple
async fds
- Support for exchanging the new IBTA defiend ECE data during RDMA CM
exchanges
- Removal of the very old and insecure FMR interface from all ULPs
and drivers. FRWR should be preferred for at least a decade now"

This fixes a crash introduced by recent is_kdump_kernel() check.
The source of the crash is that kdump kernel can be loaded on a
system with already created VFs. But for such VFs, it will follow
a logic path of PF and eventually crash.
Thus, we are partially reverting back previous changes and instead
use is_kdump_kernel is a single init point of PF init, where we
disable SRIOV explicitly.

When converting the MSCC PHY driver to shared PHY packages, the Serdes
configuration in vsc8584_config_init was modified to use 'base_addr'
instead of 'base' as the port number. But 'base_addr' isn't equal to
'addr' for all PHYs inside the package, which leads to the Serdes still
being enabled on those ports. This patch fixes it.

Commit ca23cb0bc50f ("mvneta: MVNETA_SKB_HEADROOM set last 3 bits to zero")
added headroom alignment check against 8.
Hovewer (if we imagine that NET_SKB_PAD or XDP_PACKET_HEADROOM is not
aligned to cacheline size), it actually aligns headroom down, while
skb/xdp_buff headroom should be *at least* equal to one of the values
(depending on XDP prog presence).
So, fix the check to align the value up. This satisfies both
hardware/driver and network stack requirements.

Th referenced change added an extra hw reset to rtl8169_net_suspend()
what makes WoL fail on few chip versions. Therefore skip the extra

In rtl_shutdown() rtl8169_hw_reset() is called by rtl8169_net_suspend()
already if needed, therefore avoid issues issue by removing the extra
call. The fix was tested on a system with RTL8168g.
Meanwhile rtl8169_hw_reset() does more than a hw reset and should be

If the geneve interface is in collect_md (external) mode, it can't send any
packets submitted directly to its net interface, as such packets won't have
metadata attached. This is expected.
However, the kernel itself sends some packets to the interface, most
notably, IPv6 DAD, IPv6 multicast listener reports, etc. This is not wrong,
as tunnel metadata can be specified in routing table (although technically,
that has never worked for IPv6, but hopefully will be fixed eventually) and
then the interface must correctly participate in IPv6 housekeeping.
The problem is that any such attempt increases the tx_error counter. Just
bringing up a geneve interface with IPv6 enabled is enough to see a number
of tx_errors. That causes confusion among users, prompting them to find
a network error where there is none.
Change the counter used to tx_dropped. That better conveys the meaning
(there's nothing wrong going on, just some packets are getting dropped) and
hopefully will make admins panic less.

This patch fixes two issues with XDP:
1. If the XDP verdict is XDP_ABORTED we break the loop, which results in
us handling one buffer per napi cycle instead of the total budget
(usually 64). To overcome this simply change the xdp_verdict check to
!= XDP_PASS. When the verdict is XDP_PASS, the skb is not expected to
be NULL.
2. Update the residual budget for XDP_DROP and XDP_ABORTED, since
packets are handled in these cases.

When sending very high packet rate, the XDP tx queues can get full and
start dropping packets. In this case we don't free the pages which
results in ena driver draining the system memory.
Fix:
Simply free the pages when necessary.
