HW/FW support two types of latency enhancement features. Until now user-space implemented only edpm (enhanced dpm). We add kernel capability flags to differentiate between current FW in kernel that supports both ldpm and edpm. Since edpm is not yet supported for iWARP we add different flags for iWARP + RoCE. We also fix bad practice of defining sizes in rdma-core and pass initialization to kernel, for forward compatibility. The capability flags are added for backward-forward compatibility between kernel and rdma-core for qedr. Before this change there was a field called dpm_enabled which could hold either 0 or 1 value, this indicated whether RoCE edpm was enabled or not. We modified this field to be dpm_flags, and bit 1 still holds the same meaning of RoCE edpm being enabled or not.
