Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Cross-merge networking fixes after downstream PR.
No conflicts (sort of) and no adjacent changes.
This merge reverts commit b3c9e65eb227 ("net: hsr: remove seqnr_lock")
from net, as it was superseded by
commit 430d67bdcb04 ("net: hsr: Use the seqnr lock for frames received via interlink port.")
in net-next.
