David writes:
"Networking:
A few straggler bug fixes:
1) Fix indexing of multi-pass dumps of ipv6 addresses, from David
Ahern.
2) Revert RCU locking change for bonding netpoll, causes worse
problems than it solves.
3) pskb_trim_rcsum_slow() doesn't handle odd trim offsets, resulting
in erroneous bad hw checksum triggers with CHECKSUM_COMPLETE
devices. From Dimitris Michailidis.
4) a revert to some neighbour code changes that adjust notifications
in a way that confuses some apps."
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
Revert "neighbour: force neigh_invalidate when NUD_FAILED update is from admin"
net/ipv6: Fix index counter for unicast addresses in in6_dump_addrs
net: fix pskb_trim_rcsum_slow() with odd trim offset
Revert "bond: take rcu lock in netpoll_send_skb_on_dev"
