From 72e85c45b9541e1f3d233e775da1dc6f68b85867 Mon Sep 17 00:00:00 2001 From: Jesse Gross Date: Thu, 23 Jun 2011 13:04:39 +0000 Subject: vmxnet3: Convert to new vlan model. This converts the vmxnet3 driver to use the new vlan model. In doing so it fixes missing tags in tcpdump and failure to do checksum offload when tx vlan offload is disabled.
