According to Annex17_RoCEv2 (A17.4.5.2), for RoCEv2 UD, a CQE should
carry a flag that indicates if the received frame is an IPv4, IPv6 or
RoCE packet. But currently, the values of the flag corresponding to
these packet types haven't been defined yet in WC.
In UCX, 'sl' in ibv_wc for UD is used as the packet type flag, and the
packet type values have already been defined in the UCX patch of
ed28845b88
Therefore, to adapt UCX, add a create flag to hnsdv_create_qp() to allow
users to choose whether they use 'sl' in ibv_wc as service level or
packet type for UD. For the latter, obtain and translate the packet type
from CQE and fill it to 'sl' in ibv_wc.
