From 869070c5300d1b6f0f72f5444e69fe65e34c6bde Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 5 Sep 2013 22:46:10 +0100 Subject: [PATCH] sfc: Reset derived rx_bad_bytes statistic when EF10 MC is rebooted If the MC reboots then the stats it reports to us will have been reset. We need to reset ours to get efx_update_diff_stat() working properly. (This is a re-run of commit 876be083b669 'sfc: Reset driver's MAC stats after MC reboot seen'.)
