X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=73422913cab53307214cd13c4fa2c11bf222c2ab;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ixgbe: Remove unneeded register writes in VF VLAN setup

The driver is unnecessarily writing values to VLAN control registers.
These writes already done elsewhere and are superfluous here.
