From 3b644cf6cef0324c595b86181220901b5bed0b99 Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Fri, 27 Jun 2008 10:59:48 -0700 Subject: [PATCH] igb: Remove adapter struct from these function call parameters Simplify a bunch of calls to these functions by moving the adapter struct out of the function arguments since that is not needed.
