net: bfin_mac: Remove unused stats member from struct bfin_mac_local
The bfin_mac driver keeps its statistics in net_device->stats, so the stats member in struct bfin_mac_local is unused. Remove it, as well as the accompanying comment. Cc: adi-buildroot-devel@lists.sourceforge.net Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
