 Hello Eugene,
 
 IMHO it's not easy to apply your patch to CURRENT directly without
 additional patches.  When I wrote urtw(4) it based on realtek's linux
 driver and at that moment it didn't support adhoc and hostap modes.  Not
 sure it's working on other chipsets though I don't know what you're
 using.
