Merge tag 'net-5.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Networking fixes for 5.10-rc3, including fixes from wireless, can, and
  netfilter subtrees.

  Current merge window - bugs in new features:

   - can: isotp: isotp_rcv_cf(): enable RX timeout handling in
     listen-only mode

  Previous releases - regressions:

   - mac80211:
      - don't require VHT elements for HE on 2.4 GHz
      - fix regression where EAPOL frames were sent in plaintext

   - netfilter:
      - ipset: Update byte and packet counters regardless of whether
        they match

   - ip_tunnel: fix over-mtu packet send by allowing fragmenting even if
     inner packet has IP_DF (don't fragment) set in its header (when
     TUNNEL_DONT_FRAGMENT flag is not set on the tunnel dev)

   - net: fec: fix MDIO probing for some FEC hardware blocks

   - ip6_tunnel: set inner ipproto before ip6_tnl_encap to un-break gso
     support

   - sctp: Fix COMM_LOST/CANT_STR_ASSOC err reporting on big-endian
     platforms, sparse-related fix used the wrong integer size

  Previous releases - always broken:

   - netfilter: use actual socket sk rather than skb sk when routing
     harder

   - r8169: work around short packet hw bug on RTL8125 by padding frames

   - net: ethernet: ti: cpsw: disable PTPv1 hw timestamping
     advertisement, the hardware does not support it

   - chelsio/chtls: fix always leaking ctrl_skb and another leak caused
     by a race condition

   - fix drivers incorrectly writing into skbs on TX:
      - cadence: force nonlinear buffers to be cloned
      - gianfar: Account for Tx PTP timestamp in the skb headroom
      - gianfar: Replace skb_realloc_headroom with skb_cow_head for PTP

   - can: flexcan:
      - remove FLEXCAN_QUIRK_DISABLE_MECR quirk for LS1021A
      - add ECC initialization for VF610 and LX2160A
      - flexcan_remove(): disable wakeup completely

   - can: fix packet echo functionality:
      - peak_canfd: fix echo management when loopback is on
      - make sure skbs are not freed in IRQ context in case they need to
        be dropped
      - always clone the skbs to make sure they have a reference on the
        socket, and prevent it from disappearing
      - fix real payload length return value for RTR frames

   - can: j1939: return failure on bind if netdev is down, rather than
     waiting indefinitely

  Misc:

   - IPv6: reply ICMP error if the first fragment don't include all
     headers to improve compliance with RFC 8200"
