Merge tag 'net-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes and stragglers from Jakub Kicinski:
"Networking stragglers and fixes, including changes from netfilter,
wireless and can.
Current release - regressions:
- qrtr: revert check in qrtr_endpoint_post(), fixes audio and wifi
- ip_gre: validate csum_start only on pull
- bnxt_en: fix 64-bit doorbell operation on 32-bit kernels
- ionic: fix double use of queue-lock, fix a sleeping in atomic
- can: c_can: fix null-ptr-deref on ioctl()
- cs89x0: disable compile testing on powerpc
Current release - new code bugs:
- bridge: mcast: fix vlan port router deadlock, consistently disable
BH
Previous releases - regressions:
- dsa: tag_rtl4_a: fix egress tags, only port 0 was working
- mptcp: fix possible divide by zero
- netfilter: nft_ct: protect nft_ct_pcpu_template_refcnt with mutex
- netfilter: socket: icmp6: fix use-after-scope
- stmmac: fix MAC not working when system resume back with WoL active
Previous releases - always broken:
- ip/ip6_gre: use the same logic as SIT interfaces when computing
v6LL address
- seg6: set fc_nlinfo in nh_create_ipv4, nh_create_ipv6
- mptcp: only send extra TCP acks in eligible socket states
- dsa: lantiq_gswip: fix maximum frame length
- stmmac: fix overall budget calculation for rxtx_napi
- bnxt_en: fix firmware version reporting via devlink
- renesas: sh_eth: add missing barrier to fix freeing wrong tx
descriptor
Stragglers:
- netfilter: conntrack: switch to siphash
- netfilter: refuse insertion if chain has grown too large
- ncsi: add get MAC address command to get Intel i210 MAC address"
