Subject: netpoll: Visit all napi handlers in poll_napi
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=eb8143b469e5e11e05487648d27e176e907fec1f;p=deliverable%2Flinux.git

netpoll: Visit all napi handlers in poll_napi

In poll_napi loop through all of the napi handlers even when the
budget falls to 0 to ensure that we process all of the tx_queues, and
so that we continue to call into drivers when our initial budget is 0.
