* tg3: Create aliases for rx producer mailbox regsMatt Carlson2009-11-16
| | | | | | | | | | | The rx producer mailbox registers are used in several spots in the code. The addition of TG3_64BIT_REG_LOW makes register references uncomfortably long. This patch creates an alias for the standard and jumbo ring producer index registers to make the code cleaner.

* tg3: Fix phylib locking strategyMatt Carlson2009-10-07
| | | | | | | | | | Felix Radensky noted that chip resets were generating stack trace dumps.

* tg3: Add MDIO bus address assignmentsMatt Carlson2009-09-02
| | | | | | | | | | | | The 5717 is a dual port chip that has a shared MDIO bus design.
