Ok, sta_addr is used from following structs.

struct ieee_param {
u32 cmd;
u8 sta_addr[ETH_ALEN];
union {
...
...
}; u
};

struct ieee_param_ex {
u32 cmd;
u8 sta_addr[ETH_ALEN];
u8 data[0];
};

Well, looking at it now, I'm not sure about the alignment anymore
in the struct that contains the union. Is sta_addr in the first
struct __aligned(2)?

Should I include the snippets in the commit message, or is just
writing that sta_addr is __aligned(2) enough? (if it is in the
first case...)

Regards,
Michael
