Subject: [net-next PATCH 03/12] net: Add NETIF_F_FCOE_MTU to indicate support for a different MTU for FCoE
Date: Fri, 14 Aug 2009 15:41:57 -0700 [thread overview]
Message-ID: <20090814224156.1640.59034.stgit@localhost.localdomain> (raw)
In-Reply-To: <20090814223857.1640.26881.stgit@localhost.localdomain>
From: Yi Zou <yi.zou@intel.com>
Add NETIF_F_FCOE_MTU to indicate that the NIC can support a secondary MTU for
converged traffic of LAN and Fiber Channel over Ethernet (FCoE). The MTU for
FCoE is 2158 = 14 (FCoE header) + 24 (FC header) + 2112 (FC max payload) +
4 (FC CRC) + 4 (FCoE trailer).
