Subject[PATCH 04/13] bridge: netfilter: Convert compare_ether_addr to ether_addr_equal
Date
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)

@@
expression a,b;
@@
- compare_ether_addr(a, b)
+ !ether_addr_equal(a, b)

@@

- !ether_addr_equal(a, b) == 0
