| |
-stable review patch. If anyone has any objections, please let us know.
------------------ From: Stephen Hemminger <shemminger@osdl.org>
Receiving VLAN packets over a device (without VLAN assist) that is doing hardware checksumming (CHECKSUM_HW), causes errors because the VLAN code forgets to adjust the hardware checksum.
