This callback further invokes the mlxfw module to flash the new

As the firmware flash process takes about 20 seconds and ethtool
takes the rtnl lock during the flash_device callback, we release
the rtnl lock at the beginning of the flash process and take it
again before leaving the callback.

This way, rtnl is not held during the process. To make sure the
device does not get deleted while being flashed, we take a
reference to it before releasing rtnl lock.

Introduce a Page-Reuse mechanism in non-Striding RQ RX datapath.

A WQE (RX descriptor) buffer is a page, that in most cases was fully
wasted on a packet that is much smaller, requiring a new page for
the next round.

In this patch, we implement a page-reuse mechanism, that resembles a
`SW Striding RQ`.
We allow the WQE to reuse its allocated page as much as it could,
until the page is fully consumed.  In each round, the WQE is capable
of receiving packet of maximal size (MTU). Yet, upon the reception of
a packet, the WQE knows the actual packet size, and consumes the exact
amount of memory needed to build a linear SKB. Then, it updates the
buffer pointer within the page accordingly, for the next round.

Feature is mutually exclusive with XDP (packet-per-page)
and LRO (session size is a power of two, needs unused page).

Performance tests:
iperf tcp tests show huge gain:

num streams | BW before | BW after | ratio |

In addition, take this headroom into account when calculating the

These are not needed in Striding RQ as they're done implicitly

for connected socket, the incoming_cpu field in the sock struct
is not going to change frequently, but we are setting it
unconditionally for each packet.

Since sk_incoming_cpu and sk_flags share the same cacheline,
and the latter is access by udp_recvmsg(), this cause a cache
miss for each packet for UDP connected socket.

With this patch, we set the incoming cpu field only when the
ingress cpu really changes.

This gives a small but measurable performance improvement for

This adds the new getsockopt(2) option SO_PEERGROUPS on SOL_SOCKET to
retrieve the auxiliary groups of the remote peer. It is designed to
naturally extend SO_PEERCRED. That is, the underlying data is from the
same credentials. Regarding its syntax, it is based on SO_PEERSEC. That
is, if the provided buffer is too small, ERANGE is returned and @optlen
is updated. Otherwise, the information is copied, @optlen is set to the
actual size, and 0 is returned.

While SO_PEERCRED (and thus `struct ucred') already returns the primary
group, it lacks the auxiliary group vector. However, nearly all access
controls (including kernel side VFS and SYSVIPC, but also user-space
polkit, DBus, ...) consider the entire set of groups, rather than just
the primary group. But this is currently not possible with pure
SO_PEERCRED. Instead, user-space has to work around this and query the
system database for the auxiliary groups of a UID retrieved via
SO_PEERCRED.

Unfortunately, there is no race-free way to query the auxiliary groups
of the PID/UID retrieved via SO_PEERCRED. Hence, the current user-space
solution is to use getgrouplist(3p), which itself falls back to NSS and
whatever is configured in nsswitch.conf(3). This effectively checks
which groups we *would* assign to the user if it logged in *now*. On
normal systems it is as easy as reading /etc/group, but with NSS it can
resort to quering network databases (eg., LDAP), using IPC or network
communication.

Long story short: Whenever we want to use auxiliary groups for access
checks on IPC, we need further IPC to talk to the user/group databases,
rather than just relying on SO_PEERCRED and the incoming socket. This
is unfortunate, and might even result in dead-locks if the database
query uses the same IPC as the original request.

So far, those recursions / dead-locks have been avoided by using
primitive IPC for all crucial NSS modules. However, we want to avoid
re-inventing the wheel for each NSS module that might be involved in
user/group queries. Hence, we would preferably make DBus (and other IPC
that supports access-management based on groups) work without resorting
to the user/group database. This new SO_PEERGROUPS ioctl would allow us
to make dbus-daemon work without ever calling into NSS.

and XDP_TX action support.

Jake fixes a possible NULL pointer dereference in
i40evf_get_ethtool_stats() which could occur if the VF fails to recover
from a reset, and then a user requests statistics.  Changed the use of
dev_info() to dev_dbg() for vf_capability client routine so that the

why udp_port has be in host byte order and to avoid future changes which
may cause this to break.  Fixed the holding of the RTNL lock for the
entire reset routine, reduced the scope so that the reset function will
handle its own lock, so that we do not have to wrap every reference
to i40e_do_reset() with RTNL lock/unlock.

Alice updates flags related to firmware interactions for WoL and admin
queue command address with the correct value.

Sudheer makes a fix to ensure that the array is not accessed past the
size of the array.

Greg fixes the parsing of firmware 4.33 admin queue commmand "Get CEE
DCBX PER CFG" because the firmware now creates the oper_prio_tc nibbles
reversed from those in the CDD Priority Group sub-TLV.

Carolyn adds a check and message to let users know that when in MFP mode,
changing RSS hash input set is not supported.

Shannon makes the partition bandwidth control more generic since it is not
in just one form of multi-function partitioning (MFP).  Also fixes a bug
which was causing the firmware confusion in some reset sequences, when
we were disabling interrupts and we were clearing the whole register.
Instead we should only be clearing the CAUSE_ENA bit when disabling
interrupts.

Filip adds support for OEM firmware version, so that if a OEM specific
adapter is detected, ethtool reports the OEM product version in the
firmware version string instead of etrack id.

Alan fixes a bug where the driver was not correctly exiting overflow
promiscuous mode, which can happen if "too many" MAC filters are added,
putting the driver into overflow promiscuous mode, and the filters are
then removed.  The bug occurs because the conditional for toggling
promiscuous mode was only be executed when enabled and not when it was

Currently, all ipmr/ip6mr cache reports are sent through the

- Added two rtnetlink groups with restricted-binding
- Changed cache report notified groups from RTNL_{IPV4,IPV6}_MROUTE to
