# [PATCH 13/13] dsa: Convert compare_ether_addr to ether_addr_equal

From: Joe Perches
Date: Wed May 09 2012 - 00:59:33 EST

Use the new bool function ether_addr_equal to add
some clarity and reduce the likelihood for misuse
of compare_ether_addr for sorting.

Done via cocci script:

\$ cat compare_ether_addr.cocci
@@
expression a,b;
@@
- !compare_ether_addr(a, b)
+ ether_addr_equal(a, b)

@@
