I'm not using ath9k rate control in this case, and at least most messages
get through fine.  We didn't actually see any obvious improvement when forcing
everything to 6Mbps, but since my user was asking, I wanted to run the
idea past the list.

Rate control is not perfect, and on initial bringup it doesn't have
many packets to work with so I thought it might still be useful to allow
users to specify a particular rate for EAPOL packets.  Maybe using
a socket ioctl so user-space (ie, supplicant/hostapd) can control it,
for example.
