Merge tag 'net-6.15-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Rather tiny pull request, mostly so that we can get into our trees
  your fix to the x86 Makefile.

  Current release - regressions:

   - Revert "tcp: avoid atomic operations on sk->sk_rmem_alloc", error
     queue accounting was missed

  Current release - new code bugs:

   - 5 fixes for the netdevice instance locking work

  Previous releases - regressions:

   - usbnet: restore usb%d name exception for local mac addresses

  Previous releases - always broken:

   - rtnetlink: allocate vfinfo size for VF GUIDs when supported, avoid
     spurious GET_LINK failures

   - eth: mana: Switch to page pool for jumbo frames

   - phy: broadcom: Correct BCM5221 PHY model detection

  Misc:

   - selftests: drv-net: replace helpers for referring to other files"
