Revision 1aa28fb98368078bcaf527bf46c0e001db934414 authored by Eric Dumazet on 21 September 2018, 22:27:46 UTC, committed by David S. Miller on 24 September 2018, 04:55:25 UTC
As diagnosed by Song Liu, ndo_poll_controller() can
be very dangerous on loaded hosts, since the cpu
calling ndo_poll_controller() might steal all NAPI
contexts (for all RX/TX queues of the NIC). This capture
can last for unlimited amount of time, since one
cpu is generally not able to drain all the queues under load.

i40evf uses NAPI for TX completions, so we better let core
networking stack call the napi->poll() to avoid the capture.
