Merge tag 'net-6.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from CAN and WPAN.

  Still quite a few bugs from this release. This pull is a bit smaller
  because major subtrees went into the previous one. Or maybe people
  took spring break off?

  Current release - regressions:

   - phy: micrel: correct KSZ9131RNX EEE capabilities and advertisement

  Current release - new code bugs:

   - eth: wangxun: fix vector length of interrupt cause

   - vsock/loopback: consistently protect the packet queue with
     sk_buff_head.lock

   - virtio/vsock: fix header length on skb merging

   - wpan: ca8210: fix unsigned mac_len comparison with zero

  Previous releases - regressions:

   - eth: stmmac: don't reject VLANs when IFF_PROMISC is set

   - eth: smsc911x: avoid PHY being resumed when interface is not up

   - eth: mtk_eth_soc: fix tx throughput regression with direct 1G links

   - eth: bnx2x: use the right build_skb() helper after core rework

   - wwan: iosm: fix 7560 modem crash on use on unsupported channel

  Previous releases - always broken:

   - eth: sfc: don't overwrite offload features at NIC reset

   - eth: r8169: fix RTL8168H and RTL8107E rx crc error

   - can: j1939: prevent deadlock by moving j1939_sk_errqueue()

   - virt: vmxnet3: use GRO callback when UPT is enabled

   - virt: xen: don't do grant copy across page boundary

   - phy: dp83869: fix default value for tx-/rx-internal-delay

   - dsa: ksz8: fix multiple issues with ksz8_fdb_dump

   - eth: mvpp2: fix classification/RSS of VLAN and fragmented packets

   - eth: mtk_eth_soc: fix flow block refcounting logic

  Misc:

   - constify fwnode pointers in SFP handling"
