tg3: Fix IPv6 TCP problems for 5719

Commit 9b45c018b4af2d32e2ffa2c26d327630688b4cb1, entitled
"tg3: Fix 5719 A0 tx completion bug" turned off TSO to fix a hardware
bug.  In doing so, it accidentally turned off all IPv6 TCP checksum
offloading too.  This patch fixes the problem by reenabling the hardware
bit that control both features.  The TSO capability is still not exposed
to the kernel.
