Subject: [PATCH 24/28] IB/hfi1: Rename struct ahg_ib_header to struct hfi1_ahg_info
Date: Mon, 25 Jul 2016 13:40:16 -0700	[thread overview]
Message-ID: <20160725204015.4800.86943.stgit@scvm10.sc.intel.com> (raw)
In-Reply-To: <20160725203554.4800.37248.stgit-9QXIwq+3FY+1XWohqUldA0EOCMrvLtNR@public.gmane.org>

From: Dasaratharaman Chandramouli <dasaratharaman.chandramouli-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

struct ahg_ib_header has no header specific information.
Rename it to struct hfi1_ahg_info
