From 7235ea227e19100ca748ccd6279322a166a90953 Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Fri, 1 Feb 2019 12:44:37 -0800 Subject: iw_cxgb4: use listening ep tos when accepting new connections If the parent listening endpoint has a service type set, then use that when setting up the connection. This allows server-side applications to mandate the tos for passive side connections via rdma_set_service_type() on the listening endpoints.
