bd56e71b4b 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.

a7c6aabdc3 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.

6dcc706bc5 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.

f5101b5382 - 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.

e50d35e6c6 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.

b6108616ac net80211 rate control framework (net80211 ratectl).
This framework allows drivers to abstract the rate control algorithm and
just feed the framework with the usable parameters. The rate control
framework will now deal with passing the parameters to the selected
algorithm. Right now we have AMRR (the default) and RSSADAPT but there's
no way to select one with ifconfig, yet.
The objective is to have more rate control algorithms in the net80211
stack so all drivers[0] can use it. Ideally, we'll have the well-known
sample rate control algorithm in the net80211 at some point so all
drivers can use it (not just ath).

[0] all drivers that do rate control in software, that is.

  o supports B/G and LP(low power) PHYs.
  o supports 32 / 64 bits DMA operations.

It'd not connected to the build until the firmware port is committed.
