madwifi: add patch for building all modules (except for the HAL) into a single module. saves space and gets rid of unnecessary exports removes support for onoe and amrr - I don't think anybody needs these anymore

config MADWIFI_RCA_ONOE
bool "Use the Onoe rate control algorithm"
help
Onoe is a credit based RCA where the value of the credit is determined
by the frequency of successful, erroneous and retransmissions
accumulated during a fixed invocation period of 1000 ms. If less than
10% of the packets need to be retransmitted at a particular rate, Onoe
keeps increasing its credit point till the threshold value of 10 is
reached. At this point, the current transmission rate is increased to
the next available higher rate and the process repeated with credit
score of zero. Similar logic holds for deducting the credit score and
moving to a lower bit-rate for failed packet
transmission/retransmission attempts. However, once a bit-rate has
been marked as failure in the previous attempt, Onoe will not attempt
to select that bit-rate until 10 seconds have elapsed since the last
attempt. Due to the manner in which it operates, Onoe is conservative
in rate selection and is less sensitive to individual packet failure.
config MADWIFI_RCA_AMRR
bool "Use the AMRR rate control algorithm"
help
AMRR uses Binary Exponential Backoff (BEB) technique to adapt the
length (threshold) of the sampling period used to change the values of
bit-rate and transmission count parameters. It uses probe packets and
depending on their transmission status adaptively changes the threshold
value. The adaptation mechanism ensures fewer failed
transmission/retransmission and higher throughput by not switching to a
higher rate as specified by the backoff mechanism. In addition to this,
the AMRR employs heuristics to capture the short-term variations of the
channel by judiciously setting the rate and transmission count
parameters.
