From 46b250311dac828bcb79f0807c16d4157059ce7e Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 22 May 2017 10:59:33 -0700 Subject: [PATCH] nfp: mark port state as stale if update failed If reading new state of the port failed, mark the port back as CHANGED. This way next user state request will trigger refresh, which will hopefully succeed. Signed-off-by: Jakub Kicinski Reviewed-by: Simon Horman Signed-off-by: David S.
