NAME         top

       ionic_dv_pd_get_udma_mask - Get UDMA pipeline mask of a protection
       domain

SYNOPSIS         top

              #include <infiniband/ionic_dv.h>

              uint8_t ionic_dv_pd_get_udma_mask(struct ibv_pd *ibpd);

DESCRIPTION         top

       ionic_dv_pd_get_udma_mask() returns the current UDMA pipeline mask
       associated with the protection domain or parent domain ibpd.

       The returned mask indicates which UDMA pipelines are enabled for
       queues created under this protection domain.  It may have been set
       by a prior call to ionic_dv_pd_set_udma_mask(3), or it may be the
       default mask inherited from the device context.

ARGUMENTS         top

       ibpd   The protection domain or parent domain to query.  Must be
              an ionic protection domain.

RETURN VALUE         top

       Returns the UDMA pipeline mask of the protection domain.  Returns
       0 if ibpd is not an ionic protection domain.
