From: Henrik Austad <henrik at austad.us>
The current list of E1000_TXDCTL-registers is incomplete. This adds the
missing parts for the Transmit Descriptor Control (TXDCTL) register.
The rest of these values (threshold for descriptor read/write) for
TXDCTL seems to be defined in igb/igb.h, not sure why this is split
though.
It seems that this was left out in the commit that added support for
82575 Gigabit Ethernet driver 9d5c8243 (igb: PCI-Express 82575 Gigabit
Ethernet driver).
