From e1bb7843e4c25e6e331890a2ca512581e844bbaa Mon Sep 17 00:00:00 2001 From: Dotan Barak Date: Mon, 7 Jan 2008 09:01:25 +0200 Subject: IB/mlx4: Fix value of pkey_index in QP1 completions Fix the value of pkey_index in completions to get a valid value for GSI QPs. Without this fix, incoming GSI packets on port 2 get an invalid P_Key index in the completion, which prevents the MAD layer from sending back a response, which can make the second port of ConnectX HCAs completely useless.
