[ewg] [Q] Does IPoIB bonding support VLAN??

[richard Croucher]

VLANS as such don't exist in InfiniBand so the  Linux VLAN support i.e.
vcontrol is not applicable.

Instead, you should use InfiniBand partitions.  Like VLANs these create
separated broadcast domains which you then typically use for different
IP subnets.

You are already using these,  your /dev/ib0  and /dev/ib1 just happen to
be in the default partition.

As you create additional partitions, then the server ports you then add
as members will have new /dev/ib0_part# instances created.  ie a server
with a dual port card, added to three partitions will have six /dev/ib
instances

Bear in mind if you want to bond these logical ports  that they need to
be  within the same broadcast domain
