A preparation step for enabling zero copy in NVMEoF TCP initiator. Since nvme_tcp_qpair_process_completions doesn't process poll group, we can't get asycn notification from kernel. 1. Add a qpair to poll group before we send icreq in order to be able to process buffer reclaim notification. 2. Check if qpair is connected to a poll group and call nvme_tcp_poll_group_process_completions instead of nvme_tcp_qpair_process_completions when waiting for icresp 3. Add processing of poll group to nvme_wait_for_completion_timeout and nvme_wait_for_completion_robust_lock since they are used to process FABRIC_CONNECT command Change-Id: I38d2d9496bca8d0cd72e44883df2df802e31a87d Signed-off-by: Alexey Marchuk <alexeymar@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/4208 Tested-by: SPDK CI Jenkins <sys_sgci@intel.com> Reviewed-by: Jim Harris <james.r.harris@intel.com> Reviewed-by: Ben Walker <benjamin.walker@intel.com> |
