Subject: libhns: Add the parsing of mac type in RoH mode

After parsing the mac type as RoH mode, the user driver
needs to set the dmac field of ud wqe to 0xFF, the hardware
will recognize this field, and increase the recognition of
the IP field in RoH mode, which is used for the CM link
building function in user mode.
