The function rtl2830_init contains the code:

         buf[0] = tmp << 6;
         buf[0] = (if_ctl >> 16) & 0x3f;
         buf[1] = (if_ctl >>  8) & 0xff;
         buf[2] = (if_ctl >>  0) & 0xff;

Is there any purpose to initializing buf[0] twice?

Hmm. Since 0x3f is the lowest 6 bits, it looks like the second line should use |= instead of = . I don't know anything about the rt2830 though.

Andy is correct. If you look few lines just before that you could see that logic. Patch is welcome.

Done.  Thanks for the quick responses.
