Subject: i40e: Cleanup in FDIR SB ethtool code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1eaa3840b786ac9294e9ed8e8dc3fdca29dc9091;p=linux-beck.git

i40e: Cleanup in FDIR SB ethtool code

Function add_del_fdir was used and implemented only for add. So change the name
and drop a parameter.
