Merge tag 'net-6.9-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from bpf.

  Relatively calm week, likely due to public holiday in most places. No
  known outstanding regressions.

  Current release - regressions:

   - rxrpc: fix wrong alignmask in __page_frag_alloc_align()

   - eth: e1000e: change usleep_range to udelay in PHY mdic access

  Previous releases - regressions:

   - gro: fix udp bad offset in socket lookup

   - bpf: fix incorrect runtime stat for arm64

   - tipc: fix UAF in error path

   - netfs: fix a potential infinite loop in extract_user_to_sg()

   - eth: ice: ensure the copied buf is NUL terminated

   - eth: qeth: fix kernel panic after setting hsuid

  Previous releases - always broken:

   - bpf:
       - verifier: prevent userspace memory access
       - xdp: use flags field to disambiguate broadcast redirect

   - bridge: fix multicast-to-unicast with fraglist GSO

   - mptcp: ensure snd_nxt is properly initialized on connect

   - nsh: fix outer header access in nsh_gso_segment().

   - eth: bcmgenet: fix racing registers access

   - eth: vxlan: fix stats counters.

  Misc:

   - a bunch of MAINTAINERS file updates"
