Updated copyright date to 2007.

Tested with BCM5706 A3.

Added ID for BCM5708 B2.

Removed unused driver version string.

Modified BCE_PRINTF macro to automatically fill-in the sc pointer.

Fixed a kernel panic when the driver was loaded as a module from the
command-line because the MII bus pointer was null (i.e. the MII bus
hadn't been enumerated yet).

Added fix proposed by Vladimir Ivanov <wawa@yandex-team.ru> to prevent
driver state corruption when releasing the lock during the ISR in
bce_rx_intr() to send packets up the stack.

Added new TX chain and register read sysctl interfaces for debugging.

Cleaned up formatting for various other debug routines.

Added a new statistic maintained by firmware which tracks the number
of received packets dropped because no receive buffers are available.
