Ksenija Stanojevic c63eee5460 Staging: rtl8192e: Use ether_addr_copy() instead of memcpy() 
This patch replaces memcpy with ether_addr_copy.
Also pathole was used to make sure that arguments passed to ether_addr_copy
are aligned to u16.
First argument is iwe.u.ap_addr.sa_data i output of pahole is:
struct iw_event {
	__u16                      len;                  /*     0     2 */
	__u16                      cmd;                  /*     2     2 */

	/* XXX 4 bytes hole, try to pack */

	union iwreq_data           u;                    /*     8    16 */

	/* size: 24, cachelines: 1, members: 3 */
	/* sum members: 20, holes: 1, sum holes: 4 */
	/* last cacheline: 24 bytes */
};
and inside union iwreq_data u is sa_data:
struct sockaddr {
/* typedef sa_family_t -> __kernel_sa_family_t */ short unsigned int sa_family; /*     8     2 */
char       sa_data[14];                                          /*    10    14 */
} ap_addr; /*          16 */

sa_data is a char array of size 14, and the number of bytes copied using
ether_addr_copy() is 6.

Second argument is network->bssid and output of pahole is:
struct rtllib_network {
	u8                         bssid[6];             /*     0     6 */

Sean MacLennan 3b148be0df staging/rtl8192e: Register against lib80211 
Convert rtllib from registering the crypt drivers against rtllib_crypt
and instead register the against lib80211. The crypto functions have
R- prepended (R-CCMP, R-TKIP, R-WEP) so they will not clash with the
lib80211 versions.

We cannot use the lib80211 crypt drivers since the rtl8192e has some
hardware support that is not handled by the lib80211 crypt drivers.
