Subject: [PATCH v3] staging: rtl8712: Use ether_addr_copy() instead of memcpy()

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.

No answer means that Greg hasn't gotten to it yet and no one else has
an issue with it. Wait for 2 weeks before asking or 4 weeks if a merge
window is open.

Ah. Not only are you ignorant, but you are also rude! The patch was not NACKed,
thus it will be picked up in good time.

What are these statements, sending a patch with valid proofs implies rudeness?
Does this patch still have changes..?

No, that patch (V3) is OK. Sending a ping after 2 days is most certainly rude.
That implies that no one has anything better to do than cater to your
submissions. As Greg told you, wait for a while.
