Subject: [PATCH] Drivers: staging: wlan-ng: p80211conv: replaced functions for copying/comparing ethernet addresses
Date: Wed, 30 Sep 2015 03:46:08 +0530	[thread overview]
Message-ID: <20150929221607.GA15184@ubuntu> (raw)

Replaced the function memcpy() by ether_addr_copy() and, memcmp() by
ether_addr_equal() as these functions are more preferable for copying
and comparing the ethernet addresses respectively.
Also fixed the issue of character limit of 80 per line and removed
one unnecessary statement.
