Hi all,
I've just gone and bridged tap0 to hme0 on my Ultra 10 and I stopped  
getting packets in and out of hme0. I switched off hme0 hardware  
checksums on a hunch and I started to get packets. Is this supposed  
to happen? I'm guessing not.

I'm running NetBSD/sparc64 4.0_BETA2 from a couple of days ago.

I brought up the tap and bridge with
	ifconfig tap0 create
	ifconfig bridge0 create
	brconfig bridge0 add tap0 add hme0 up

tcpdump showed no packets and ping couldn't look up host names in the  
DNS. I put tcpdump in the background then disabled hardware checksums  
and started a ping. Right away tcpdump started reporting network  

If nobody can tell me that it's supposed to work that way, I'll raise  
a PR.
