It will be made possible again through nl80211. > Adding EXPORT_SYMBOL for ieee80211_init_rate_ctrl_alg would allow the > driver to request the algorithm known to work best with that hardware. A driver is not supposed to set rate control. Under no circumstances. If you know about a bug in default rate control algorithm, fix it and send a patch. Otherwise, fix your driver. > we can change ieee80211_register_hw() to take a 'name' parameter > specifying the rate control algorithm to use.
