Since there is no connection between the MAC/VLAN and the GID
when using IP-based addressing, the proxy QP1 (running on the
slave) must pass the source-mac, destination-mac, and vlan_id
information separately from the GID. Additionally, the Host
must pass the remote source-mac and vlan_id back to the slave,
This is achieved as follows:
Outgoing MADs:
1. Source MAC: obtained from the CQ completion structure
(struct ib_wc, smac field).
2. Destination MAC: obtained from the tunnel header
3. vlan_id: obtained from the tunnel header.
Incoming MADs
1. The source (i.e., remote) MAC and vlan_id are passed in
the tunnel header to the proxy QP1.
VST mode support:
For outgoing MADs, the vlan_id obtained from the header is
discarded, and the vlan_id specified by the Hypervisor is used
instead.
For incoming MADs, the incoming vlan_id (in the wc) is discarded, and the
"invalid" vlan (0xffff) is substituted when forwarding to the slave.
