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

   - ethtool: remove link_mode param and derive link params from driver

   - 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

   - nfc: fix infinite loop, refcount & memory leaks in LLCP sockets

   - let skb_orphan_partial wake-up waiters

   - xfrm/compat: Cleanup WARN()s that can be user-triggered

* We are planning to be backward and forward compatible with changes

* When reading an event (whether the kernel from userspace or vice

* version 1 event size, but might be able to accept other sizes in
* the future.
/**
* DOC: Extensibility
*
* One exception is the kernel -- we already have two event sizes in
* that we've made the 'hard' member optional since our only option
* is to ignore it anyway.
* Originally, we had planned to allow backward and forward compatible
* changes by just adding fields at the end of the structure that are
* then not reported on older kernels on read(), and not written to by
* older kernels on write(), with the kernel reporting the size it did
* accept as the result.
*
* This would have allowed userspace to detect on read() and write()
* which kernel structure version it was dealing with, and if was just
* recompiled it would have gotten the new fields, but obviously not
* accessed them, but things should've continued to work.
*
* Unfortunately, while actually exercising this mechanism to add the
* hard block reasons field, we found that userspace (notably systemd)
* did all kinds of fun things not in line with this scheme:
*
* 1. treat the (expected) short writes as an error;
* 2. ask to read sizeof(struct rfkill_event) but then compare the
* actual return value to RFKILL_EVENT_SIZE_V1 and treat any
* mismatch as an error.
*
* As a consequence, just recompiling with a new struct version caused
* things to no longer work correctly on old and new kernels.
*
* Hence, we've rolled back &struct rfkill_event to the original version
* and added &struct rfkill_event_ext. This effectively reverts to the
* old behaviour for all userspace, unless it explicitly opts in to the
* rules outlined here by using the new &struct rfkill_event_ext.
*
* Userspace using &struct rfkill_event_ext must adhere to the following
* rules
*
* 1. accept short writes, optionally using them to detect that it's
* running on an older kernel;
* 2. accept short reads, knowing that this means it's running on an
* older kernel;
* 3. treat reads that are as long as requested as acceptable, not
* checking against RFKILL_EVENT_SIZE_V1 or such.
