Fixes Warning encounter this by applying checkpatch.pl against this file:
Prefer ether_addr_copy() over memcpy() if the Ethernet addresses
are __aligned(2)
pahole output for respective structures:
- addr->sa_data
struct sockaddr {
sa_family_t sa_family; /* 0 2 */
char sa_data[14]; /* 2 14 */
/* size: 16, cachelines: 1, members: 2 */
/* last cacheline: 16 bytes */
};
- pnetdev->dev_addr
dev_addr is interface address infor from generic net_device structure
which is properly aligned and have some patches with this change as well.
