Merge tag 'net-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Networking fixes for 5.13-rc1, including fixes from bpf, can and
  netfilter trees. Self-contained fixes, nothing risky.

  Current release - new code bugs:

   - dsa: ksz: fix a few bugs found by static-checker in the new driver

   - stmmac: fix frame preemption handshake not triggering after
     interface restart

  Previous releases - regressions:

   - make nla_strcmp handle more then one trailing null character

   - fix stack OOB reads while fragmenting IPv4 packets in openvswitch
     and net/sched

   - sctp: do asoc update earlier in sctp_sf_do_dupcook_a

   - sctp: delay auto_asconf init until binding the first addr

   - stmmac: clear receive all(RA) bit when promiscuous mode is off

   - can: mcp251x: fix resume from sleep before interface was brought up

  Previous releases - always broken:

   - bpf: fix leakage of uninitialized bpf stack under speculation

   - bpf: fix masking negation logic upon negative dst register

   - netfilter: don't assume that skb_header_pointer() will never fail

   - only allow init netns to set default tcp cong to a restricted algo

   - xsk: fix xp_aligned_validate_desc() when len == chunk_size to avoid
     false positive errors

   - ethtool: fix missing NLM_F_MULTI flag when dumping

   - can: m_can: m_can_tx_work_queue(): fix tx_skb race condition

   - sctp: fix a SCTP_MIB_CURRESTAB leak in sctp_sf_do_dupcook_b

   - bridge: fix NULL-deref caused by a races between assigning
     rx_handler_data and setting the IFF_BRIDGE_PORT bit

  Latecomer:

   - seg6: add counters support for SRv6 Behaviors"

+Description:
+		Boolean.  Default: 'N'

+		in MAP format to be passed on to the stack.
+
+		Normally the rmnet driver (CONFIG_RMNET) is then used to process
+		and demultiplex these packets.
+
+		'Pass-through' mode can be enabled when the device is in
+		'raw-ip' mode only.
