svn commit: r283994 - head/sys/net80211

[Adrian Chadd]

Author: adrian
Date: Thu Jun  4 17:54:41 2015
New Revision: 283994
URL: https://svnweb.freebsd.org/changeset/base/283994

Log:
  Tag outbound raw 802.11 frames with both the node and an mbuf tag
  with the transmit params.
  
  This allows raw 802.11 frames to be queued in the driver if necessary,
  rather than requiring it to be direct-dispatched into the hardware.
  
  Tested:
  
  * ath(4), STA mode
  * iwn(4), STA mode
  
  MFC after:	2 weeks
