Author: ivadasz

New Revision: 308185
URL: https://svnweb.freebsd.org/changeset/base/308185

Log:
  [iwm] Set full-offload scan flag. Fixes fw panic when already associated.
  
  * Starting a scan from wpa_supplicant or via ifconfig while associated,
    should no longer cause firmware panics or abort early.
  
  Tested:
  
  * AC7260, STA mode
