From: Wei Fang Date: Fri, 2 Jun 2023 09:46:59 +0000 (+0800) Subject: net: enetc: correct rx_bytes statistics of XDP X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fdebd850cc065495abf1d64756496050bb22db67;p=linux.git net: enetc: correct rx_bytes statistics of XDP The rx_bytes statistics of XDP are always zero, because rx_byte_cnt is not updated after it is initialized to 0. So fix it. Fixes: d1b15102dd16 ("net: enetc: add support for XDP_DROP and XDP_PASS") Signed-off-by: Wei Fang Reviewed-by: Vladimir Oltean Signed-off-by: David S.
