From 0b1a989ef5a751b5992842d1934e22de861a848e Mon Sep 17 00:00:00 2001 From: Pieter Jansen van Vuuren Date: Wed, 11 Apr 2018 16:47:37 -0700 Subject: [PATCH] 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.
