From 294e7d78f5b929536b81620ed33c6507f2921463 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Fri, 26 Aug 2011 07:45:57 +0000 Subject: [PATCH] igb: retire the RX_CSUM flag and use the netdev flag instead Since the netdev now has its' own checksum flag to indicate if Rx checksum is enabled we might as well use that instead of using the ring flag.
