Subject: netpoll: Visit all napi handlers in poll_napi
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=eb8143b469e5e11e05487648d27e176e907fec1f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.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.
