tg3: Work around HW/FW limitations with vlan encapsulated frames
[ Upstream commit 476c18850c6cbaa3f2bb661ae9710645081563b9 ]
TG3 appears to have an issue performing TSO and checksum offloading
correclty when the frame has been vlan encapsulated (non-accelrated).
In these cases, tcp checksum is not correctly updated.
This patch attempts to work around this issue. After the patch,
802.1ad vlans start working correctly over tg3 devices.
