From: Julia Lawall <julia.law...@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, ieee80211_bar defined in include/linux/ieee80211.h and ath_common defined in drivers/net/wireless/ath/ath.h This was done using Coccinelle (http://coccinelle.lip6.fr/).
