Subject: ixgbe: fix AF_XDP tx byte count
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=30d5703bceb0c118ef934918074768620efa93e6;p=openwrt%2Fstaging%2Fblogic.git

ixgbe: fix AF_XDP tx byte count

The tx bytecount is done twice.  When running
'./xdpsock -t -N -i eth3' and 'ip -s link show dev eth3'
The avg packet size is 120 instead of 60. So remove the
extra one.
