From: Lingyu Liu Date: Tue, 28 Mar 2023 10:49:11 +0000 (+0000) Subject: ice: Reset FDIR counter in FDIR init stage X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=83c911dc5e0e8e6eaa6431c06972a8f159bfe2fc;p=linux.git ice: Reset FDIR counter in FDIR init stage Reset the FDIR counters when FDIR inits. Without this patch, when VF initializes or resets, all the FDIR counters are not cleaned, which may cause unexpected behaviors for future FDIR rule create (e.g., rule conflict).
