This patch fixes the following checkpatch.pl warning: Prefer ether_addr_copy() over memcpy() if the Ethernet addresses are __aligned(2) The changes were applied using the following coccinelle rule: @@ expression e1, e2; @@ - memcpy(e1, e2, ETH_ALEN); + ether_addr_copy(e1, e2); All variables defined in vnt_mac_set_key start at even offsets making the variables aligned to the u16 datatype.
