Code Issues Releases Wiki Activity

This time we have:

Browse source 
* some AP-side infrastructure for FILS discovery and
    unsolicited probe resonses
  * a major rework of the encapsulation/header conversion
    offload from Felix, to fit better with e.g. AP_VLAN
    interfaces
  * performance fix for VHT A-MPDU size, don't limit to HT
  * some initial patches for S1G (sub 1 GHz) support, more
    will come in this area
  * minor cleanups
