In xirc2ps_probe, the local->tx_timeout_task was bounded
with xirc2ps_tx_timeout_task. When timeout occurs,
it will call xirc_tx_timeout->schedule_work to start the
work.

When we call xirc2ps_detach to remove the driver, there
may be a sequence as follows:

Stop responding to timeout tasks and complete scheduled
tasks before cleanup in xirc2ps_detach, which will fix
the problem.

Pull networking fixes from Jakub Kicinski:
 "Including fixes from netfilter, wifi and ipsec.

  A little more changes than usual, but it's pretty normal for us that
  the rc3/rc4 PRs are oversized as people start testing in earnest.

  Possibly an extra boost from people deploying the 6.1 LTS but that's
  more of an unscientific hunch.

  Current release - regressions:

   - phy: mscc: fix deadlock in phy_ethtool_{get,set}_wol()

   - virtio: vsock: don't use skbuff state to account credit

   - virtio: vsock: don't drop skbuff on copy failure

   - virtio_net: fix page_to_skb() miscalculating the memory size

  Current release - new code bugs:

   - eth: correct xdp_features after device reconfig

   - wifi: nl80211: fix the puncturing bitmap policy

   - net/mlx5e: flower:
      - fix raw counter initialization
      - fix missing error code
      - fix cloned flow attribute

   - ipa:
      - fix some register validity checks
      - fix a surprising number of bad offsets
      - kill FILT_ROUT_CACHE_CFG IPA register

  Previous releases - regressions:

   - tcp: fix bind() conflict check for dual-stack wildcard address

   - veth: fix use after free in XDP_REDIRECT when skb headroom is small

   - ipv4: fix incorrect table ID in IOCTL path

   - ipvlan: make skb->skb_iif track skb->dev for l3s mode

   - mptcp:
      - fix possible deadlock in subflow_error_report
      - fix UaFs when destroying unaccepted and listening sockets

   - dsa: mv88e6xxx: fix max_mtu of 1492 on 6165, 6191, 6220, 6250, 6290

  Previous releases - always broken:

   - tcp: tcp_make_synack() can be called from process context, don't
     assume preemption is disabled when updating stats

   - netfilter: correct length for loading protocol registers

   - virtio_net: add checking sq is full inside xdp xmit

   - bonding: restore IFF_MASTER/SLAVE flags on bond enslave Ethertype
     change

   - phy: nxp-c45-tja11xx: fix MII_BASIC_CONFIG_REV bit number

   - eth: i40e: fix crash during reboot when adapter is in recovery mode

   - eth: ice: avoid deadlock on rtnl lock when auxiliary device
     plug/unplug meets bonding

   - dsa: mt7530:
      - remove now incorrect comment regarding port 5
      - set PLL frequency and trgmii only when trgmii is used

   - eth: mtk_eth_soc: reset PCS state when changing interface types

bonding: properly restore flags when bond changes ether type

A bug was reported by syzbot[1] that causes a warning and a myriad of
other potential issues if a bond, that is also a slave, fails to enslave a
non-eth device. While fixing that bug I found that we have the same
issues when such enslave passes and after that the bond changes back to
ARPHRD_ETHER (again due to ether_setup). This set fixes all issues by
extracting the ether_setup() sequence in a helper which does the right
thing about bond flags when it needs to change back to ARPHRD_ETHER. It
also adds selftests for these cases.

Patch 01 adds the new bond_ether_setup helper and fixes the issues when a
bond device changes its ether type due to successful enslave. Patch 02
fixes the issues when it changes its ether type due to an unsuccessful
enslave. Note we need two patches because the bugs were introduced by
different commits. Patch 03 adds the new selftests.

Due to the comment adjustment and squash, could you please review
patch 01 again? I've kept the other acks since there were no code
changes.

v3: squash the helper patch and the first fix, adjust the comment above
    it to be explicit about the bond device, no code changes
v2: new set, all patches are new due to new approach of fixing these bugs

Add new network selftests for the bonding device which exercise the ether
type changing call paths. They also test for the recent syzbot bug[1] which
causes a warning and results in wrong device flags (IFF_SLAVE missing).
The test adds three bond devices and a nlmon device, enslaves one of the
bond devices to the other and then uses the nlmon device for successful
and unsuccesful enslaves both of which change the bond ether type. Thus
we can test for both MASTER and SLAVE flags at the same time.

If the flags are properly restored we get:
TEST: Change ether type of an enslaved bond device with unsuccessful enslave   [ OK ]
TEST: Change ether type of an enslaved bond device with successful enslave   [ OK ]

syzbot reported a warning[1] where the bond device itself is a slave and
we try to enslave a non-ethernet device as the first slave which fails
but then in the error path when ether_setup() restores the bond device
it also clears all flags. In my previous fix[2] I restored the
IFF_MASTER flag, but I didn't consider the case that the bond device
itself might also be a slave with IFF_SLAVE set, so we need to restore
that flag as well. Use the bond_ether_setup helper which does the right
thing and restores the bond's flags properly.

Steps to reproduce using a nlmon dev:
 $ ip l add nlmon0 type nlmon
 $ ip l add bond1 type bond
 $ ip l add bond2 type bond
 $ ip l set bond1 master bond2
 $ ip l set dev nlmon0 master bond1
 $ ip -d l sh dev bond1
 22: bond1: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noqueue master bond2 state DOWN mode DEFAULT group default qlen 1000
 (now bond1's IFF_SLAVE flag is gone and we'll hit a warning[3] if we
  try to delete it)

Add bond_ether_setup helper which is used to fix ether_setup() calls in the
bonding driver. It takes care of both IFF_MASTER and IFF_SLAVE flags, the
former is always restored and the latter only if it was set.
If the bond enslaves non-ARPHRD_ETHER device (changes its type), then
releases it and enslaves ARPHRD_ETHER device (changes back) then we
use ether_setup() to restore the bond device type but it also resets its
flags and removes IFF_MASTER and IFF_SLAVE[1]. Use the bond_ether_setup
helper to restore both after such transition.

[1] reproduce (nlmon is non-ARPHRD_ETHER):
 $ ip l add nlmon0 type nlmon
 $ ip l add bond2 type bond mode active-backup
 $ ip l set nlmon0 master bond2
 $ ip l set nlmon0 nomaster
 $ ip l add bond1 type bond
 (we use bond1 as ARPHRD_ETHER device to restore bond2's mode)
 $ ip l set bond1 master bond2
 $ ip l sh dev bond2
 37: bond2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether be:d7:c5:40:5b:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 1500
 (notice bond2's IFF_MASTER is missing)

====================
net: ipa: minor bug fixes

The four patches in this series fix some errors, though none of them
cause any compile or runtime problems.

The first changes the files included by "drivers/net/ipa/reg.h" to
ensure everything it requires is included with the file.  It also
stops unnecessarily including another file.  The prerequisites are
apparently satisfied other ways, currently.

The second adds two struct declarations to "gsi_reg.h", to ensure
they're declared before they're used later in the file.  Again, it
seems these declarations are currently resolved wherever this file
is included.

The third removes register definitions that were added for IPA v5.0
that are not needed.  And the last updates some validity checks for
IPA v5.0 registers.  No IPA v5.0 platforms are yet supported, so the
issues resolved here were never harmful.

Versions 2 and 3 of this series change the "Fixes" tags in patches
so they supply legitimate commit hashes.
