errors (especially when jumbo frames are enabled or in low memory systems)
because the RX chain was corrupted when an mbuf was mapped to an unexpected
number of buffers.
- Fixed a problem that would cause kernel panics when an excessively
fragmented TX mbuf couldn't be defragmented and was released by
bce_tx_encap().

MFC after: 7 days
- Updated firmware to latest release (v3.4.8) to fix TSO + jumbo frame lockup
- Added MSI (hw.bce.msi_enable) and TSO (hw.bce.tso_enable) sysctls
- Fixed kernel panic when MSI is used and module is unloaded
- Added several new debug routines
- Removed slack space for RX/TX chains since it only covers sloppy coding
- Fixed a potential problem when programming jumbo MTU size in hardware
- Various other comment changes

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.
