Verifying RoCE v1 or v2 GID Index, and Address from sys and class Parameters

Use one of the following options to verify RoCE v1 or v2 GID Index and address

from the sys and class parameters below:

 Option 1

# cat /sys/class/infiniband/qedr0/ports/1/gid_attrs/types/0

IB/RoCE v1

# cat /sys/class/infiniband/qedr0/ports/1/gid_attrs/types/1

RoCE v2

# cat /sys/class/infiniband/qedr0/ports/1/gids/0

fe80:0000:0000:0000:020e:1eff:fec4:1b20

#cat /sys/class/infiniband/qedr0/ports/1/gids/1

fe80:0000:0000:0000:020e:1eff:fec4:1b20

 Option 2

Use the scripts from the fastlinq-minor source package.

NOTE

You must specify the GID index values for RoCE v1 or v2 based on

server or switch configuration (Pause/PFC). Use GID index for Link

local IPv6 address, or GID index for IPv4 address, or GID index for

IPv6 address. In order to use VLAN tagged frames for RoCE traffic,

you must specify GID index values that are derived from VLAN IPv4 or

IPv6 address.
