Replace memcmp() with ether_addr_equal(). In every location where the
replacement was done, the addresses accessed are
__aligned(2). Structures accessed either stack or heap allocated, no
direct memory casts to possibly unaligned structs are used.
Involved structures:
typedef struct hfa384x_authenticateStation_data {
u8 address[ETH_ALEN]; /* 0 offset */
...
} __packed hfa384x_authenticateStation_data_t;
struct prism2sta_authlist {
unsigned int cnt;
u8 addr[WLAN_AUTH_MAX][ETH_ALEN]; /* 4 bytes offset,
addresses start
at u16 boundary */
u8 assoc[WLAN_AUTH_MAX];
};
struct prism2sta_accesslist {
unsigned int modify;
unsigned int cnt;
u8 addr[WLAN_ACCESS_MAX][ETH_ALEN]; /* 8 bytes offset,
multiple of u16 */
...
u8 addr1[WLAN_ACCESS_MAX][ETH_ALEN]; /* starts at u32 boundary,
struct not packed */
};
typedef struct hfa384x_AssocStatus {
u16 assocstatus;
u8 sta_addr[ETH_ALEN]; /* 2 bytes offset,
struct is packed */
u8 old_ap_addr[ETH_ALEN]; /* 8 bytes offset */
...
} __packed hfa384x_AssocStatus_t;
The patch resolves the following checkpatch warnings:
WARNING: Prefer ether_addr_equal() or ether_addr_equal_unaligned()
over memcmp()

TODO: - checkpatch.pl cleanups - sparse warnings - move to use the in-kernel wireless stack Please send any patches or complaints about this driver to Greg Kroah-Hartman <greg@kroah.com> and don't bother the upstream wireless kernel developers about it, they want nothing to do with it.
