Subject: i40evf: Use macro param for ethtool stats
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c7b8d978a6087d2bdcc6c79cab07dc58888b89fc;p=linux-beck.git

i40evf: Use macro param for ethtool stats

Use a macro parameter for ethtool stats instead of just assuming
that a valid netdev variable exists. Suggested by Ben Hutchings.
