I think I've lost the plot a bit here.
> The 3 bit user priority field is identical to the 3 bits of the SL.
I'm having a hard time figuring out what this sentence has to do with
this patch. I don't see anywhere in the patch where the sl field is
used except for copying the TOS into it, and I don't see what "user
priority field" might be referring to.
Also, how do VLANs work with multicast? As far as I can tell, there are
no spare bits in an IB MGID or IPv6 multicast address that can be stolen
to use for a VLAN ID. For example, how would I create an AH to use to
send to MGID ff02::1 on VLAN 25?
