>Description:
	bridge(4) doesn't take care of checksum offloading.
>How-To-Repeat:
	
>Fix:
	- bridge_forward() should clear out csum_flags.
	- bridge_output() and bridge_broadcast() should do checksum
	  if the interface has no h/w checksum support.
	  (or don't delay checksumming for bridge member.)
