| |
From: Julia Lawall <Julia.Lawall@lip6.fr>
Ether_addr_equal_64bits is more efficient than ether_addr_equal, and can be used when each argument is an array within a structure that contains at least two bytes of data beyond the array.
The structures involved are: ieee80211_hdr defined in include/linux/ieee80211.h and p54_common defined in drivers/net/wireless/p54/p54.h
This was done using Coccinelle (http://coccinelle.lip6.fr/).
