Subject: [NET-NEXT PATCH 02/18] igb: Remove adapter struct from these function call parameters
Date: Fri, 27 Jun 2008 10:59:48 -0700 [thread overview]
Message-ID: <20080627175941.22428.13019.stgit@localhost.localdomain> (raw)
In-Reply-To: <20080627175921.22428.52767.stgit@localhost.localdomain>
From: Mitch Williams <mitch.a.williams@intel.com>
Simplify a bunch of calls to these functions by moving the adapter
struct out of the function arguments since that is not needed.
