Merge tag 'net-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Current release - always broken:

   - net/smc: fix access to parent of an ib device

   - devlink: use _BITUL() macro instead of BIT() in the UAPI header

   - handful of mptcp fixes

  Previous release - regressions:

   - intel: AF_XDP: clear the status bits for the next_to_use descriptor

   - dpaa2-eth: fix the size of the mapped SGT buffer

  Previous release - always broken:

   - mptcp: fix security context on server socket

   - ethtool: fix string set id check

   - ethtool: fix error paths in ethnl_set_channels()

   - lan743x: fix rx_napi_poll/interrupt ping-pong

   - qca: ar9331: fix sleeping function called from invalid context bug"
