Subject: [net-next 3/8] ixgbevf: Make use of NETIF_F_RXCSUM instead of keeping our own flag
Date: Tue, 17 Jul 2012 03:09:14 -0700 [thread overview]
Message-ID: <1342519759-25137-4-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1342519759-25137-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Alexander Duyck <alexander.h.duyck@intel.com>
The IXGBE_FLAG_RX_CSUM_ENABLED flag is redundant since NETIF_F_RXCSUM is
keeping the value we want to already have. As such we can drop the
redundant flag and just make use of NETIF_F_RXCSUM.
