It becomes difficult to make out from the output of ibv_devinfo
if a particular gid index is RoCE v2 or not.
Adding a string to the output of ibv_devinfo -v to display the
gid type at the end of gid.
The output would look something like below:
$ ibv_devinfo -v -d bnxt_re2
hca_id: bnxt_re2
transport: InfiniBand (0)
fw_ver: 216.0.220.0
node_guid: b226:28ff:fed3:b0f0
sys_image_guid: b226:28ff:fed3:b0f0
.

phys_state: LINK_UP (5)
GID[ 0]: fe80:0000:0000:0000:b226:28ff:fed3:b0f0, IB/RoCE v1
GID[ 1]: fe80:0000:0000:0000:b226:28ff:fed3:b0f0, RoCE v2
GID[ 2]: 0000:0000:0000:0000:0000:ffff:c0aa:0165, IB/RoCE v1
GID[ 3]: 0000:0000:0000:0000:0000:ffff:c0aa:0165, RoCE v2
