Subject: sfc: Move test of rx_checksum_enabled from nic.c to rx.c
X-Git-Tag: v3.0~749^2~517^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ab3cf6d0f3d2daeef2101a2a97b6c0beee6b70cf;p=platform%2Fkernel%2Flinux-amlogic.git

sfc: Move test of rx_checksum_enabled from nic.c to rx.c

This is preparation for using the generic netdev features interface,
and should have no effect in itself.
