From a18b0ee409d3382aa556b8f06a6cd6bfbef3f5c8 Mon Sep 17 00:00:00 2001 From: Wenpeng Liang Date: Tue, 11 May 2021 19:06:38 +0800 Subject: libhns: Set srqlimit to 0 when creating SRQ According to the IB specification, the srq_limt parameter should not be configured when creating srq. But the libhns does not set attr.srq_limit to 0 currently. As a result, when attr.srq_limit provided by the user is not 0, the value of attr.srq_limit returned to the user will be different from that obtained by ibv_query_srq(). Therefore, the driver should set attr.srq_limit to 0 when creating SRQ.
