Thanks.

For this problem, I'd prefer to check for a NULL src_addr in resolve_lid and 
resolve_gid.  The ibacm service could then select a SLID/SGID based on the 
specified DLID/DGID.  This makes things easier for the user.

But until ibacm handles a 0 SLID/SGID, have ib_acme provide a more usable 
failure message.

I can make this patch if this sounds workable to you.
