With commit 34d21de9 ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core instead
of this driver.

With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.

Move qtnfmac driver to leverage the core allocation.

net: intel: start The Great Code Dedup + Page Pool for iavf

Alexander Lobakin says:

Here's a two-shot: introduce {,Intel} Ethernet common library (libeth and
libie) and switch iavf to Page Pool. Details are in the commit messages;
here's a summary:

Not a secret there's a ton of code duplication between two and more Intel
ethernet modules. Before introducing new changes, which would need to be
copied over again, start decoupling the already existing duplicate
functionality into a new module, which will be shared between several
Intel Ethernet drivers. The first name that came to my mind was
"libie" -- "Intel Ethernet common library". Also this sounds like
"lovelie" (-> one word, no "lib I E" pls) and can be expanded as
"lib Internet Explorer" :P
The "generic", pure-software part is placed separately, so that it can be
easily reused in any driver by any vendor without linking to the Intel
pre-200G guts. In a few words, it's something any modern driver does the
same way, but nobody moved it level up (yet).
The series is only the beginning. From now on, adding every new feature
or doing any good driver refactoring will remove much more lines than add
for quite some time. There's a basic roadmap with some deduplications
planned already, not speaking of that touching every line now asks:
"can I share this?". The final destination is very ambitious: have only
one unified driver for at least i40e, ice, iavf, and idpf with a struct
ops for each generation. That's never gonna happen, right? But you still
can at least try.
PP conversion for iavf lands within the same series as these two are tied
closely. libie will support Page Pool model only, so that a driver can't
use much of the lib until it's converted. iavf is only the example, the
rest will eventually be converted soon on a per-driver basis. That is
when it gets really interesting. Stay tech.

Someone complains the message appears continuously. This occurs
because the device is woken from UPS mode, and the driver re-loads
the firmware.

When the device enters runtime suspend and cable is unplugged, the
device would enter UPS mode. If the runtime resume occurs, and the
device is woken from UPS mode, the driver has to re-load the firmware
and causes the message. If someone wakes the device continuously, the
message would be shown continuously, too. Use dev_dbg to avoid it.

Note that, the function could be called before register_netdev(), so I
don't use netif_info() or netif_dbg().

The module uses Rollball protocol to talk to the PHY, and needs a 4

I had failures with pmtu.sh selftests lately,
with netns dismantles firing ref_tracking alerts [1].

After much debugging, I found that some queued
rcu callbacks were delayed by minutes, because
of CONFIG_RCU_LAZY=y option.

Joel Fernandes had a similar issue in the past,
fixed with commit 483c26ff ("net: Use call_rcu_hurry()
for dst_release()")

In this commit, I make sure nexthop_free_rcu()
and free_fib_info_rcu() are not delayed too much
because they both can release device references.

tools/testing/selftests/net/pmtu.sh no longer fails.

While testing TCP performance with latest trees,
I saw suspect SOCKET_BACKLOG drops.

tcp_add_backlog() computes its limit with :

    limit = (u32)READ_ONCE(sk->sk_rcvbuf) +
            (u32)(READ_ONCE(sk->sk_sndbuf) >> 1);
    limit += 64 * 1024;

This does not take into account that sk->sk_backlog.len
is reset only at the very end of __release_sock().

Both sk->sk_backlog.len and sk->sk_rmem_alloc could reach
sk_rcvbuf in normal conditions.

We should double sk->sk_rcvbuf contribution in the formula
to absorb bubbles in the backlog, which happen more often
for very fast flows.

This change maintains decent protection against abuses.

====================
wireless-next patches for v6.10

The second "new features" pull request for v6.10 with changes both in
stack and in drivers. This time the pull request is rather small and
nothing special standing out except maybe that we have several
kernel-doc fixes. Great to see that we are getting warning free
wireless code (until new warnings are added).

Major changes:

rtl8xxxu:
 * enable Management Frame Protection (MFP) support

rtw88:
 * disable unsupported interface type of mesh point for all chips, and only
   support station mode for SDIO chips.

Pull networking fixes from Jakub Kicinski:
 "Including fixes from netfilter, wireless and bluetooth.

  Nothing major, regression fixes are mostly in drivers, two more of
  those are flowing towards us thru various trees. I wish some of the
  changes went into -rc5, we'll try to keep an eye on frequency of PRs
  from sub-trees.

  Also disproportional number of fixes for bugs added in v6.4, strange
  coincidence.

  Current release - regressions:

   - igc: fix LED-related deadlock on driver unbind

   - wifi: mac80211: small fixes to recent clean up of the connection
     process

   - Revert "wifi: iwlwifi: bump FW API to 90 for BZ/SC devices", kernel
     doesn't have all the code to deal with that version, yet

   - Bluetooth:
       - set power_ctrl_enabled on NULL returned by gpiod_get_optional()
       - qca: fix invalid device address check, again

   - eth: ravb: fix registered interrupt names

  Current release - new code bugs:

   - wifi: mac80211: check EHT/TTLM action frame length

  Previous releases - regressions:

   - fix sk_memory_allocated_{add|sub} for architectures where
     __this_cpu_{add|sub}* are not IRQ-safe

   - dsa: mv88e6xx: fix link setup for 88E6250

  Previous releases - always broken:

   - ip: validate dev returned from __in_dev_get_rcu(), prevent possible
     null-derefs in a few places

   - switch number of for_each_rcu() loops using call_rcu() on the
     iterator to for_each_safe()

   - macsec: fix isolation of broadcast traffic in presence of offload

   - vxlan: drop packets from invalid source address

   - eth: mlxsw: trap and ACL programming fixes

   - eth: bnxt: PCIe error recovery fixes, fix counting dropped packets

   - Bluetooth:
       - lots of fixes for the command submission rework from v6.4
       - qca: fix NULL-deref on non-serdev suspend

  Misc:

   - tools: ynl: don't ignore errors in NLMSG_DONE messages"
