Handling the zero STag in receive work request requires some extra logic in the driver: - Only set the QP_PRIV bit for kernel mode QPs. - Add a zero STag build function for recv wrs. The uP needs a PBL allocated and passed down in the recv WR so it can construct a HW PBL for the zero STag S/G entries. Note: we need to place a few restrictions on zero STag usage because of this: 1) all SGEs in a recv WR must either be zero STag or not. No mixing. 2) an individual SGE length cannot exceed 128MB for a zero-stag SGE. This should be OK since it's not really practical to allocate such a large chunk of pinned contiguous DMA mapped memory. - Add an optimized non-zero-STag recv wr format for kernel users. This is needed to optimize both zero and non-zero STag cracking in the recv path for kernel users. - Remove the iwch_ prefix from the static build functions. - Bump required FW version.
