Merge tag 'net-6.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from netfilter.

  As Paolo promised we continue to hammer out issues in our selftests.
  This is not the end but probably the peak.

  Current release - regressions:

   - smc: fix incorrect SMC-D link group matching logic

  Current release - new code bugs:

   - eth: bnxt: silence WARN() when device skips a timestamp, it happens

  Previous releases - regressions:

   - ipmr: fix null-deref when forwarding mcast packets

   - conntrack: evaluate window negotiation only for packets in the
     REPLY direction, otherwise SYN retransmissions trigger incorrect
     window scale negotiation

   - ipset: fix performance regression in swap operation

  Previous releases - always broken:

   - tcp: add sanity checks to types of pages getting into the rx
     zerocopy path, we only support basic NIC -> user, no page cache
     pages etc.

   - ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()

   - nt_tables: more input sanitization changes

   - dsa: mt7530: fix 10M/100M speed on MediaTek MT7988 switch

   - bridge: mcast: fix loss of snooping after long uptime, jiffies do
     wrap on 32bit

   - xen-netback: properly sync TX responses, protect with locking

   - phy: mediatek-ge-soc: sync calibration values with MediaTek SDK,
     increase connection stability

   - eth: pds: fixes for various teardown, and reset races

  Misc:

   - hsr: silence WARN() if we can't alloc supervision frame, it
     happens"
