Merge tag 'net-6.0-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from ipsec and netfilter (with one broken Fixes tag).

  Current release - new code bugs:

   - dsa: don't dereference NULL extack in dsa_slave_changeupper()

   - dpaa: fix <1G ethernet on LS1046ARDB

   - neigh: don't call kfree_skb() under spin_lock_irqsave()

  Previous releases - regressions:

   - r8152: fix the RX FIFO settings when suspending

   - dsa: microchip: keep compatibility with device tree blobs with no
     phy-mode

   - Revert "net: macsec: update SCI upon MAC address change."

   - Revert "xfrm: update SA curlft.use_time", comply with RFC 2367

  Previous releases - always broken:

   - netfilter: conntrack: work around exceeded TCP receive window

   - ipsec: fix a null pointer dereference of dst->dev on a metadata dst
     in xfrm_lookup_with_ifid

   - moxa: get rid of asymmetry in DMA mapping/unmapping

   - dsa: microchip: make learning configurable and keep it off while
     standalone

   - ice: xsk: prohibit usage of non-balanced queue id

   - rxrpc: fix locking in rxrpc's sendmsg

  Misc:

   - another chunk of sysctl data race silencing"
