Since the basic rate flag is the same as the MCS flag, we can only use one. * Introduce some accessor inlines that do PLCP and rate table lookup/access and enforce that it doesn't set the basic rate bit. They're not designed for MCS rates, so it will panic. * Start converting drivers that use the rate table stuff to use the accessor inlines and strip the basic flag. * Teach AMRR about basic 11n - it's still as crap for MCS as it is being used by iwn, so it's not a step _backwardS_. * Convert iwn over to accept 11n MCS rates rather than 'translate' legacy to MCS rates. It doesn't use a lookup table any longer; instead it's a function which takes the current node (for HT parameters) and the rate code, and returns the hardware PLCP code to use. Tested: * ath - it's a no-op, and it works that way * iwn - both 11n and non-11n Mechanically substitute flags from historic mbuf allocator with 2012-12-04T09:32:43Z Gleb Smirnoff glebius@FreeBSD.org 2012-12-04T09:32:43Z urn:sha1:c6499eccad497913a5025fbde8ae76da70e08043 malloc(9) flags in sys/dev.

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.

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. MFC after: 1 month
