---help---
Say Y here if you intend to attach an Atheros Cardbus or PCI
wireless Ethernet networking card to your computer. This
driver support the standard Linux Wireless Extensions.
You will also very likely also need the Wireless Tools in order to
configure your card and that /etc/pcmcia/wireless.opts works:
<http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
To compile this driver as a module, choose M here: the module will be
called ath_pci. If unsure, say N.

SampleRate chooses the bitrate it predicts will provide the
most throughput based on estimates of the expected per-packet
transmission time for each bitrate. SampleRate periodically
sends packets at bitrates other than the current one to
estimate when another bitrate will provide better performance.
SampleRate switches to another bitrate when its estimated
per-packet transmission time becomes smaller than the current
bitrate's. SampleRate reduces the number of bitrates it must
sample by eliminating those that could not perform better than
the one currently being used. SampleRate also stops probing at
a bitrate if it experiences several successive losses.

Similar to the SampleRate code base, except that it is
a)more carefully written
b)shown to give a throughput similar to what can be obtained by
manually fixing either end to fixed rates
c)verified by monitoring the network traffic with an ieee80211
enabled ethereal
d)responds to network changes and does modify the rate accordingly.
Thus, on moving the two nodes together/apart, the ideal rate will
be changed as appropriate.
