From: Alexander Duyck Date: Wed, 6 May 2009 10:25:01 +0000 (+0000) Subject: igbvf: cleanup flags and allow for rx checksum to be disabled X-Git-Tag: v2.6.31-rc1~14^2~545 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0364d6fd2c353d2d82da865a6f093f97c69b669c;p=platform%2Fkernel%2Flinux-3.10.git igbvf: cleanup flags and allow for rx checksum to be disabled This patch cleans up a number of unused or unneeded feature flags. As a result of these changes the user should now be able to enable or disable rx checksumming via ethtool. Signed-off-by: Alexander Duyck Signed-off-by: Jeff Kirsher Signed-off-by: David S.
