Subject: [PATCH] ath9k: Fix address management
|
|
|
|
Since both the arguments need to satisfy
|
|
the alignment requirements of ether_addr_copy(),
|
|
use memcpy() in cases where there will be no
|
|
big performance benefit and make sure that
|
|
ether_addr_copy() calls use properly aligned
|
|
arguments.
