Subject: [PATCH 17/27] IB/hfi1, rdmavt: Update copy_sge to use boolean arguments
Date: Wed, 08 Feb 2017 05:27:31 -0800	[thread overview]
Message-ID: <20170208132730.16442.70413.stgit@scvm10.sc.intel.com> (raw)
In-Reply-To: <20170208132142.16442.69329.stgit-9QXIwq+3FY+1XWohqUldA0EOCMrvLtNR@public.gmane.org>

From: Brian Welty <brian.welty-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

Convert copy_sge and related SGE state functions to use boolean.
For determining if QP is in user mode, add helper function in rdmavt_qp.h.
This is used to determine if QP needs the last byte ordering.
While here, change rvt_pd.user to a boolean.
