This abstracts away and centralizes some of the necessary logic for correctly polling the IBV CQ. This also encapsulates the polling state in the efa_ibv_cq struct, rather than using local variables during the polling procedures. Signed-off-by: Darryl Abbate <[email protected]>
This also adds a flag to efa_rdm_pke to indicate headerless packets, as well as a sentinel packet type value for headerless packets Signed-off-by: Darryl Abbate <[email protected]>

This leverages a specialized procedure for processing outstanding completions of an EP to be closed. Unless RM is enabled (FI_RM_ENABLED) and the packet types are RECEIPT or EOR, the packet entries are simply released. Otherwise, the packets are queued for reposting if RNR was encountered. This avoids a lot of overhead with the standard completion polling procedure. Signed-off-by: Darryl Abbate <[email protected]>
