IB/core: Add VLAN support for IBoE
Add 802.1q VLAN support to IBoE. The VLAN tag is encoded within the GID derived from a link local address in the following way: GID[11] GID[12] contain the VLAN ID when the GID contains a VLAN. The 3 bits user priority field of the packets are identical to the 3 bits of the SL. In case of rdma_cm apps, the TOS field is used to generate the SL field by doing a shift right of 5 bits effectively taking to 3 MS bits of the TOS field.
