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 Sponsored by: Norse Corp, Inc.
