From 6ad4edfcd7b6321da34e7cd0c88dd97adddd7f57 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Fri, 26 Aug 2011 07:45:26 +0000 Subject: igb: avoid unnecessary conversions from u16 to int There are a number of places where we have values that are stored as u16 but are being converted to int unnecessarily. In order to avoid that we should convert all variables that deal with the next_to_clean, next_to_use, and count to u16 values.
