NAT under performing direct connection by 10x

[Malcolm Matalka]

I have done some more experiments and determined the NAT issue is a
complete red herring.

It looks like the problem is the USB WiFi Dongle.  It can receive at ~1
MB/s, but only push out at ~80 KB/s.  I am in hostap mode so scping data
into it works as expected but scp'ing data out of it does not.

The primary two options are that I have configured the interface wrong
or the driver has something going on in it.

I plan on perusing freebsd-wireless and the Bugzilla for any
indication.  Perhaps, though, somewhere here has experienced a similar
situation.

The driver I am using:

module by hand for now.
