From b5df9b7a2f965b7903850d8f89846ffe0080b84b Mon Sep 17 00:00:00 2001 From: Wenpeng Liang Date: Sat, 30 Jan 2021 16:58:01 +0800 Subject: [PATCH] RDMA/hns: Force srq_limit to 0 when creating SRQ According to the IB Specification, srq_limit shouldn't be configured during SRQ creation. If a user set srq_limit at this time, the driver should forced it to zero, or the result of creating SRQ will conflict with the result of querying SRQ.
