From 2da36d44a9d54a2c6e1f8da1f7ccc26b0bc6cfec Mon Sep 17 00:00:00 2001 From: Jianchao Wang Date: Thu, 26 Apr 2018 11:52:39 +0800 Subject: IB/rxe: add RXE_START_MASK for rxe_opcode IB_OPCODE_RC_SEND_ONLY_INV w/o RXE_START_MASK, the last_psn of IB_OPCODE_RC_SEND_ONLY_INV will not be updated in update_wqe_psn, and the corresponding wqe will not be acked in rxe_completer due to its last_psn is zero. Finally, the other wqe will also not be able to be acked, because the wqe of IB_OPCODE_RC_SEND_ONLY_INV with last_psn 0 is still there. This causes large amount of io timeout when nvmeof is over rxe. Add RXE_START_MASK for IB_OPCODE_RC_SEND_ONLY_INV to fix this.
