Merge branch 'bonding-report-transmit-status-to-callers'
Eric Dumazet says:
====================
bonding: report transmit status to callers
First patches cleanup netpoll, and make sure it provides tx status to its users.
Last patch changes bonding to not pretend packets were sent without error.
By providing more accurate status, TCP stack can avoid adding more
packets if the slave qdisc is already full.
This came while testing latest horizon feature in sch_fq, with
very low pacing rate flows, but should benefit hosts under stress.
