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 git-svn-id: svn://svn.openwrt.org/openwrt/trunk@17314 3c298f89-4303-0410-b956-a3cf2f4a3e73

-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.
