Merge tag 'net-5.13-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
"Networking fixes for 5.13-rc4, including fixes from bpf, netfilter,
can and wireless trees. Notably including fixes for the recently
announced "FragAttacks" WiFi vulnerabilities. Rather large batch,
touching some core parts of the stack, too, but nothing hair-raising.

Current release - regressions:

- tipc: make node link identity publish thread safe

- dsa: felix: re-enable TAS guard band mode

- stmmac: correct clocks enabled in stmmac_vlan_rx_kill_vid()

- stmmac: fix system hang if change mac address after interface
ifdown

Current release - new code bugs:

- mptcp: avoid OOB access in setsockopt()

- bpf: Fix nested bpf_bprintf_prepare with more per-cpu buffers

- ethtool: stats: fix a copy-paste error - init correct array size

Previous releases - regressions:

- sched: fix packet stuck problem for lockless qdisc

- net: really orphan skbs tied to closing sk

- mlx4: fix EEPROM dump support

- bpf: fix alu32 const subreg bound tracking on bitwise operations

- bpf: fix mask direction swap upon off reg sign change

- bpf, offload: reorder offload callback 'prepare' in verifier

- stmmac: Fix MAC WoL not working if PHY does not support WoL

- packetmmap: fix only tx timestamp on request

- tipc: skb_linearize the head skb when reassembling msgs

Previous releases - always broken:

- mac80211: address recent "FragAttacks" vulnerabilities

- mac80211: do not accept/forward invalid EAPOL frames

- mptcp: avoid potential error message floods

- bpf, ringbuf: deny reserve of buffers larger than ringbuf to
prevent out of buffer writes

- bpf: forbid trampoline attach for functions with variable arguments

- bpf: add deny list of functions to prevent inf recursion of tracing
programs

- tls splice: check SPLICE_F_NONBLOCK instead of MSG_DONTWAIT

- can: isotp: prevent race between isotp_bind() and
isotp_setsockopt()

- netfilter: nft_set_pipapo_avx2: Add irq_fpu_usable() check,
fallback to non-AVX2 version

Misc:

- bpf: add kconfig knob for disabling unpriv bpf by default"

NFC: nfcmrvl: fix kernel-doc syntax in file headers

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
The header for drivers/nfc/nfcmrvl follows this syntax, but the content
inside does not comply with kernel-doc.

This line was probably not meant for kernel-doc parsing, but is parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warnings from kernel-doc.
For e.g., running scripts/kernel-doc -none on drivers/nfc/nfcmrvl/spi.c
causes warning:
warning: expecting prototype for Marvell NFC(). Prototype was for SPI_WAIT_HANDSHAKE() instead

Provide a simple fix by replacing such occurrences with general comment
format, i.e. '/*', to prevent kernel-doc from parsing it.
