X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0f90300f4fd30968a4d40fe47a9043be9912cb31;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ixgbevf: Enables 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 82599ES.
