Merge tag 'net-6.13-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

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

  Nothing major here. Over the last two weeks we gathered only around
  two-thirds of our normal weekly fix count, but delaying sending these
  until -rc7 seemed like a really bad idea.

  AFAIK we have no bugs under investigation. One or two reverts for
  stuff for which we haven't gotten a proper fix will likely come in the
  next PR.

  Current release - fix to a fix:

   - netfilter: nft_set_hash: unaligned atomic read on struct
     nft_set_ext

   - eth: gve: trigger RX NAPI instead of TX NAPI in gve_xsk_wakeup

  Previous releases - regressions:

   - net: reenable NETIF_F_IPV6_CSUM offload for BIG TCP packets

   - mptcp:
      - fix sleeping rcvmsg sleeping forever after bad recvbuffer adjust
      - fix TCP options overflow
      - prevent excessive coalescing on receive, fix throughput

   - net: fix memory leak in tcp_conn_request() if map insertion fails

   - wifi: cw1200: fix potential NULL dereference after conversion to
     GPIO descriptors

   - phy: micrel: dynamically control external clock of KSZ PHY, fix
     suspend behavior

  Previous releases - always broken:

   - af_packet: fix VLAN handling with MSG_PEEK

   - net: restrict SO_REUSEPORT to inet sockets

   - netdev-genl: avoid empty messages in NAPI get

   - dsa: microchip: fix set_ageing_time function on KSZ9477 and LAN937X

   - eth:
      - gve: XDP fixes around transmit, queue wakeup etc.
      - ti: icssg-prueth: fix firmware load sequence to prevent time
        jump which breaks timesync related operations

  Misc:

   - netlink: specs: mptcp: add missing attr and improve documentation"
