commit 91890af1caaa170e09a5051c0c51db1ddb493f34 Author: Antonio Quartulli antonio@meshcoding.com Date: Tue Dec 10 19:39:00 2013 +0100
batadv: Slight optimization of batadv_compare_eth
Use the newly added generic routine ether_addr_equal_unaligned to test if possibly unaligned to u16 Ethernet addresses are equal.
This slightly improves comparison time for systems with CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS.
