struct rtl_stats is rather huge (152 bytes), and since
rtl8812ae_rx_command_packet_handler() does not modify it, it might as
well be passed by const reference.

It causes an interesting warning for me:

and gcc is entirely correct: that loop iterates from 0 to 3, and does this:
rtldm->bb_swing_idx_ofdm[p] = rtldm->default_ofdm_index;
but the bb_swing_idx_ofdm[] array only has two members. So the last
two iterations will overwrite bb_swing_idx_ofdm_current and the first
entry in bb_swing_idx_ofdm_base[].
Now, the bug does seem to be benign: bb_swing_idx_ofdm_current isn't
actually ever *used* as far as I can tell, and the first entry of
bb_swing_idx_ofdm_base[] will have been written with that same
"rtldm->default_ofdm_index" value.
But gcc is absolutely correct, and that driver needs fixing.
I've pulled it and will let it be because it doesn't seem to be an
issue in practice, but please fix it. The obvious fix would seem to
change the size of "2" to be "MAX_RF_PATH", but I'll abstain from
doing those kinds of changes in the merge when it doesn't seem to
affect the build or functionality).

This comes directly from the Realtek tarball, filename:
wifi_driver_8821ae_0018.1129.2013.tar.gz
I mushed the three modules (btcoexist, rtlwifi and rtl8821ae) together
into one, in order to make it all build as one stand-alone module.
After the btcoexist driver gets merged upstream, I'll pull it out of
here, and will continue to work on removing this version of rtlwifi in
order to use the in-kernel one.
