Pull networking fixes from Jakub Kicinski:
"Networking fixes including fixes from can, xfrm, wireless,
wireless-drivers and netfilter trees. Nothing scary, Intel
WiFi-related fixes seemed most notable to the users.
Current release - regressions:
- dsa: microchip: ksz8795: fix KSZ8794 port map again to program the
CPU port correctly
Current release - new code bugs:
- iwlwifi: pcie: reschedule in long-running memory reads
Previous releases - regressions:
- iwlwifi: dbg: don't try to overwrite read-only FW data
- iwlwifi: provide gso_type to GSO packets
- octeontx2: make sure the buffer is 128 byte aligned
- tcp: make TCP_USER_TIMEOUT accurate for zero window probes
- xfrm: fix wraparound in xfrm_policy_addr_delta()
- xfrm: fix oops in xfrm_replay_advance_bmp due to a race between
CPUs in presence of packet reorder
- tcp: fix TLP timer not set when CA_STATE changes from DISORDER to
OPEN
- wext: fix NULL-ptr-dereference with cfg80211's lack of commit()
Previous releases - always broken:
- igc: fix link speed advertising
- stmmac: configure EHL PSE0 GbE and PSE1 GbE to 32 bits DMA
addressing
- team: protect features update by RCU to avoid deadlock
- xfrm: fix disable_xfrm sysctl when used on xfrm interfaces
themselves
- fec: fix temporary RMII clock reset on link up
- can: dev: prevent potential information leak in can_fill_info()
Misc:
- mrp: fix bad packing of MRP test packet structures
- uapi: fix big endian definition of ipv6_rpl_sr_hdr
- add David Ahern to IPv4/IPv6 maintainers"
