Merge tag 'net-6.6-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from CAN and BPF.

  We have a regression in TC currently under investigation, otherwise
  the things that stand off most are probably the TCP and AF_PACKET
  fixes, with both issues coming from 6.5.

  Previous releases - regressions:

   - af_packet: fix fortified memcpy() without flex array.

   - tcp: fix crashes trying to free half-baked MTU probes

   - xdp: fix zero-size allocation warning in xskq_create()

   - can: sja1000: always restart the tx queue after an overrun

   - eth: mlx5e: again mutually exclude RX-FCS and RX-port-timestamp

   - eth: nfp: avoid rmmod nfp crash issues

   - eth: octeontx2-pf: fix page pool frag allocation warning

  Previous releases - always broken:

   - mctp: perform route lookups under a RCU read-side lock

   - bpf: s390: fix clobbering the caller's backchain in the trampoline

   - phy: lynx-28g: cancel the CDR check work item on the remove path

   - dsa: qca8k: fix qca8k driver for Turris 1.x

   - eth: ravb: fix use-after-free issue in ravb_tx_timeout_work()

   - eth: ixgbe: fix crash with empty VF macvlan list"
