From: Heiner Kallweit Date: Fri, 10 Aug 2018 20:39:29 +0000 (+0200) Subject: r8169: don't configure csum function per chip version X-Git-Tag: v4.19~410^2~61^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=eb88f5f7128ced3d6ab81004686035fb03087475;p=platform%2Fkernel%2Flinux-rpi.git r8169: don't configure csum function per chip version We don't have to configure the csum function per chip (sub-)version. The distinction is simple, versions RTL8102e and from RTL8168c onwards support csum_v2. Signed-off-by: Heiner Kallweit Signed-off-by: David S.
