Hi, I am studying the implemtation of efa_rdm_protocol_v4 in efa provider. I have some question below:
When a requestor send a LONGCTS_RTR packet to a responder, the responder will try to allocate a rx_entry according to the LONGCTS_RTR packet, but the allocation of rx_entry may fail, the handling of the failure seems to log a error and report an eq error to this upper layer? see rxr_pkt_handle_longcts_rtw_recv(). And the requestor is not notified of the error, it seems the tx_entry for the LONGCTS_RTR in the requestor will be stuck untill the EP is freed?
Thanks.
Not sure where the discussion we had yesterday went.
You are right, in case rx_entry cannot be allocated. The requester will stuck
