Ok.

Good to know. I was just a bit confused with the manpages that say
they're optional after I discovered looking at the driver that they're
hardwired in.

Sure:

(kgdb) p *rs
$1 = {rs_datalen = 244, rs_status = 0 '\0', rs_phyerr = 0 '\0',
rs_rssi = 0 '\0', rs_keyix = 127 '\177', rs_rate = 27 '\033', rs_more
= 0 '\0', rs_tstamp = 2097280, rs_antenna = 8399232, rs_rssi_ctl =
"0\200)", rs_rssi_ext = "\200\000\037", rs_isaggr = 1 '\001',
rs_moreaggr = 1 '\001', rs_num_delims = 0 '\0', rs_flags = 252 'ü',
rs_evm0 = 0, rs_evm1 = 0, rs_evm2 = 0, rs_evm3 = 0, rs_evm4 = 0}

Thanks!
