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 https://github.com/openucx/ucx/commit/ed28845b88633e65d64fce8ec880060aa61bd59c 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. Singed-off-by: Juan Zhou <zhoujuan51@h-partners.com> |
