Merge tag 'net-6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

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

  Current release - regressions:

   - four fixes for the netdev per-instance locking

  Current release - new code bugs:

   - consolidate more code between existing Rx zero-copy and uring so
     that the latter doesn't miss / have to duplicate the safety checks

  Previous releases - regressions:

   - ipv6: fix omitted Netlink attributes when using SKIP_STATS

  Previous releases - always broken:

   - net: fix geneve_opt length integer overflow

   - udp: fix multiple wrap arounds of sk->sk_rmem_alloc when it
     approaches INT_MAX

   - dsa: mvpp2: add a lock to avoid corruption of the shared TCAM

   - dsa: airoha: fix issues with traffic QoS configuration / offload,
     and flow table offload

  Misc:

   - touch up the Netlink YAML specs of old families to make them usable
     for user space C codegen"
