Currently all radiotap structures in ral(4) are packed, but are not aligned, which causes ral based devices to crash when one does 'ifconfig wlan0 up' for a wlan interface with a ral wlandev on arches that care about structure alignment (e.g., MIPS). Adding an aligned attribute helps fix this problem and ral devices can be properly brought up. Reviewed by: adrian Sponsored by: Smartcom - Bulgaria AD
