X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f2701b185e05d0897a47f6a14da40a068b0644ff;p=openwrt%2Fstaging%2Fblogic.git

e1000e: Enable TSO for stacked VLAN

Setting ndo_features_check to passthru_features_check allows the driver
to skip the check for multiple tagged TSO packets and enables stacked
VLAN TSO.
Tested with I217-LM.
