staging: rtl8712: replace memset(x,0,ETH_ALEN)
Author: Aya Mahfouz <mahfouz.saif.elyazal@gmail.com>
eth_zero_addr() is a wrapper function for memset if 0 is going to
be assigned to a mac address. The aforementioned function replaces
memset. In addition, linux/etherdevice.h was included as a header
since it is the file that defines the inline function eth_zero_addr().
The changes were carried out using the following coccinelle script:
@header@

#include
