Merge tag 'net-5.16-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from wireless, and wireguard.
Mostly scattered driver changes this week, with one big clump in
mv88e6xxx. Nothing of note, really.
Current release - regressions:
- smc: keep smc_close_final()'s error code during active close
Current release - new code bugs:
- iwlwifi: various static checker fixes (int overflow, leaks, missing
error codes)
- rtw89: fix size of firmware header before transfer, avoid crash
- mt76: fix timestamp check in tx_status; fix pktid leak;
- mscc: ocelot: fix missing unlock on error in ocelot_hwstamp_set()
Previous releases - regressions:
- smc: fix list corruption in smc_lgr_cleanup_early
- ipv4: convert fib_num_tclassid_users to atomic_t
Previous releases - always broken:
- tls: fix authentication failure in CCM mode
- vrf: reset IPCB/IP6CB when processing outbound pkts, prevent
incorrect processing
- dsa: mv88e6xxx: fixes for various device errata
- rds: correct socket tunable error in rds_tcp_tune()
- ipv6: fix memory leak in fib6_rule_suppress
- wireguard: reset peer src endpoint when netns exits
- wireguard: improve resilience to DoS around incoming handshakes
- tcp: fix page frag corruption on page fault which involves TCP
- mpls: fix missing attributes in delete notifications
- mt7915: fix NULL pointer dereference with ad-hoc mode
Misc:
- rt2x00: be more lenient about EPROTO errors during start
- mlx4_en: update reported link modes for 1/10G"
