From 9db8bbcb9bc68e7f58e13d30eec87905e2b8825d Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 27 Nov 2018 22:24:53 -0800 Subject: [PATCH] nfp: run representor TX locklessly Our representors are software devices built on top of the PF vNIC, the only state they have are per-cpu stats, so make the TX run locklessly.
