Merge tag 'net-5.11-rc3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull more networking fixes from Jakub Kicinski:
"Slightly lighter pull request to get back into the Thursday cadence.
Current release - always broken:
- can: mcp251xfd: fix Tx/Rx ring buffer driver race conditions
- dsa: hellcreek: fix led_classdev build errors
Previous releases - regressions:
- ipv6: fib: flush exceptions when purging route to avoid netdev
reference leak
- ip_tunnels: fix pmtu check in nopmtudisc mode
- ip: always refragment ip defragmented packets to avoid MTU issues
when forwarding through tunnels, correct "packet too big" message
is prohibitively tricky to generate
- s390/qeth: fix locking for discipline setup / removal and during
recovery to prevent both deadlocks and races
- mlx5: Use port_num 1 instead of 0 when delete a RoCE address
Previous releases - always broken:
- cdc_ncm: correct overhead calculation in delayed_ndp_size to
prevent out of bound accesses with Huawei 909s-120 LTE module
- fix stmmac dwmac-sun8i suspend/resume:
- PHY being left powered off
- MAC syscon configuration being reset
- reference to the reset controller being improperly dropped
- qrtr: fix null-ptr-deref in qrtr_ns_remove
- can: tcan4x5x: fix bittiming const, use common bittiming from m_can
driver
- mlx5e: CT: Use per flow counter when CT flow accounting is enabled
- mlx5e: Fix SWP offsets when vlan inserted by driver
Misc:
- bpf: Fix a task_iter bug caused by a bpf -> net merge conflict
resolution
And the usual many fixes to various error paths"
