[PATCH net-next 03/14] tg3: Create TG3_FLG3_5717_PLUS flag

From: Matt Carlson <hidden>
Date: 2010-08-02 21:26:42
Subsystem: networking drivers, the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

This patch creates a TG3_FLG3_5717_PLUS flag to collectively describe
the set of changes in the ASIC that will apply to all future chip
revisions.
