Remove dead code, "error" doesn't change between this check and the previous one.

Pull ieee80211_ratectl_node_init() calls from drivers into net80211. This fixes hostap mode for at least ral(4) and run(4), because there is no sufficient call into drivers which could be used initialize the node related ratectl variables.

Instead of using the AMRR ratectl algo as default for drivers which have the IEEE80211_C_RATECTL flag set, default to NONE for all drivers. Only if a driver calls ieee80211_ratectl_init() check if the NONE algo is still selected and try to use AMRR in that case. Drivers are still free to use any other algo by calling ieee80211_ratectl_set() prior to the ieee80211_ratectl_init() call. After this change it is now safe to assume that a ratectl algo is always available and selected, which renders the IEEE80211_C_RATECTL flag pretty much useless. Therefore revert r211314 and 211546.

Add new tunable 'net.link.ifqmaxlen' to set default send interface queue length. The default value for this parameter is 50, which is quite low for many of today's uses and the only way to modify this parameter right now is to edit if_var.h file. Also add read-only sysctl with the same name, so that it's possible to retrieve the current value.

Fixes a bug for LP PHY that some frames have 2 padding bytes at the start so we should adjust the mbuf if the driver is running in PIO mode. Now it should work well with WPA authentication and association for LP PHY devices. Tested by: Warren Block

Introduce IEEE80211_C_RATECTL, drivers which use the ratectl framework should set this capability. Initialize ni_txrate after txparams have been setup. Some drivers calculate various things prior to association based on ni_txrate and rely on it being nonzero. PR: kern/149185

- fixes a bug that it didn't initialize the ratectl after association; so ni_txrate returned 0 which is a invalid result. - The fourth argument of ieee80211_ratectl_tx_complete() could be not NULL. Reported by: Gustau P?rez Tested by: Gustau P?rez , Ian FREISLICH
