From fc89afce349a70f73d9c0b6d91a15c4913f071a0 Mon Sep 17 00:00:00 2001 From: Dotan Barak Date: Tue, 9 Jan 2007 11:53:07 +0200 Subject: IB/mthca: Allow the QP state transition RESET->RESET RESET->RESET is an allowed QP state transition, so mthca should handle it correctly, by just returning success without involving the firmware.
