Pull networking fixes from Jakub Kicinski:
"Networking fixes for 5.12-rc7, including fixes from can, ipsec,
mac80211, wireless, and bpf trees.
No scary regressions here or in the works, but small fixes for 5.12
changes keep coming.
Current release - regressions:
- virtio: do not pull payload in skb->head
- virtio: ensure mac header is set in virtio_net_hdr_to_skb()
- Revert "net: correct sk_acceptq_is_full()"
- mptcp: revert "mptcp: provide subflow aware release function"
- ethernet: lan743x: fix ethernet frame cutoff issue
- dsa: fix type was not set for devlink port

- sched: htb: fix null pointer dereference on a null new_q
- wireless: iwlwifi: Fix softirq/hardirq disabling in
iwl_pcie_enqueue_hcmd()
- wireless: iwlwifi: fw: fix notification wait locking
- wireless: brcmfmac: p2p: Fix deadlock introduced by avoiding the
rtnl dependency
Current release - new code bugs:
- napi: fix hangup on napi_disable for threaded napi
- bpf: take module reference for trampoline in module
- wireless: mt76: mt7921: fix airtime reporting and related tx hangs
- wireless: iwlwifi: mvm: rfi: don't lock mvm->mutex when sending
config command

triggers an ICMP reply
- can: fix msg_namelen values depending on CAN_REQUIRED_SIZE
- can: uapi: mark union inside struct can_frame packed
- sched: cls: fix action overwrite reference counting
- sched: cls: fix err handler in tcf_action_init()

Previous releases - always broken:
- bpf: Refuse non-O_RDWR flags in BPF_OBJ_GET
- bpf: Refcount task stack in bpf_get_task_stack
- bpf, x86: Validate computation of branch displacements
- ieee802154: fix many similar syzbot-found bugs
- fix NULL dereferences in netlink attribute handling
- reject unsupported operations on monitor interfaces
- fix error handling in llsec_key_alloc()
- xfrm: make ipv4 pmtu check honor ip header df

model
- openvswitch: fix send of uninitialized stack memory in ct limit
reply
Misc:
- udp: add get handling for UDP_GRO sockopt"
