From 66ced2eb2ab95f6ebe8033e2e0a2e61f2615377c Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Mon, 25 May 2020 10:22:11 -0700 Subject: RDMA/srpt: Reduce max_recv_sge to 1 Since srpt_post_recv() always sets num_sge to 1, reduce the max_recv_sge parameter that is used at queue pair allocation time to 1.
