From: Pieter Jansen van Vuuren Date: Wed, 11 Apr 2018 23:47:37 +0000 (-0700) Subject: nfp: flower: move route ack control messages out of the workqueue X-Git-Tag: v4.19~1163^2~39^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0b1a989ef5a751b5992842d1934e22de861a848e;p=platform%2Fkernel%2Flinux-rpi3.git nfp: flower: move route ack control messages out of the workqueue Previously we processed the route ack control messages in the workqueue, this unnecessarily loads the workqueue. We can deal with these messages sooner as we know we are going to drop them.
