Merge tag 'net-6.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Paolo Abeni:
"Including fixes from rxrpc, netfilter, wireless and bluetooth
subtrees.
Current release - regressions:
- skb: export skb drop reaons to user by TRACE_DEFINE_ENUM
- bluetooth: fix regression preventing ACL packet transmission
Current release - new code bugs:
- dsa: microchip: fix kernel oops on ksz8 switches
- dsa: qca8k: fix NULL pointer dereference for
of_device_get_match_data
Previous releases - regressions:
- netfilter: clean up hook list when offload flags check fails
- wifi: mt76: fix crash in chip reset fail
- rxrpc: fix ICMP/ICMP6 error handling
- ice: fix DMA mappings leak
- i40e: fix kernel crash during module removal
Previous releases - always broken:
- ipv6: sr: fix out-of-bounds read when setting HMAC data.
- tcp: TX zerocopy should not sense pfmemalloc status
- sch_sfb: don't assume the skb is still around after
enqueueing to child
- netfilter: drop dst references before setting
- wifi: wilc1000: fix DMA on stack objects
- rxrpc: fix an insufficiently large sglist in
rxkad_verify_packet_2()
- fec: use a spinlock to guard `fep->ptp_clk_on`
Misc:
- usb: qmi_wwan: add Quectel RM520N"
