From: Michael Chan Date: Mon, 6 Jun 2016 06:37:15 +0000 (-0400) Subject: bnxt_en: Enable and disable RX CTAG and RX STAG VLAN acceleration together. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5a9f6b238e59bc05afb4cdeaf3672990bf2a5309;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git bnxt_en: Enable and disable RX CTAG and RX STAG VLAN acceleration together. The hardware can only be set to strip or not strip both the VLAN CTAG and STAG. It cannot strip one and not strip the other. Add logic to bnxt_fix_features() to toggle both feature flags when the user is toggling one of them. Signed-off-by: Michael Chan Signed-off-by: David S.
