From 642aaab5a63c043c593ba9e9a86aadd388313e56 Mon Sep 17 00:00:00 2001 From: Kaike Wan Date: Mon, 21 Aug 2017 18:27:41 -0700 Subject: [PATCH] IB/hfi1: Add received request info to qp_stats The rvt_ack_entry pointed to by s_tail_ack_queue provides important info about the request that has just been processed or is being processed on the responder side of a RC connection. This patch adds this info to the qp_stats to assist debugging.
