Kalahari cards (dual and quad port PCI-e Gigabit) copper and fiber
The driver was actually tested on Oasis and Kalahari cards.

-TODO:
- - move firmware loading to request_firmware()
- - remove direct memory access of structures
- - any remaining sparse and checkpatch.pl warnings
-
- - use net_device_ops
- - use dev->stats rather than adapter->stats
- - don't cast netdev_priv it is already void
- - use compare_ether_addr
- - GET RID OF MACROS
- - work on all architectures
- - without CONFIG_X86_64 confusion
- - do 64 bit correctly
- - don't depend on order of union
- - get rid of ASSERT(), use BUG() instead but only where necessary
- looks like most aren't really useful
- - no new SIOCDEVPRIVATE ioctl allowed
- - don't use module_param for configuring interrupt mitigation
- use ethtool instead
- - reorder code to elminate use of forward declarations
- - don't keep private linked list of drivers.
- - remove all the gratiutous debug infrastructure
- - use PCI_DEVICE()
- - do ethtool correctly using ethtool_ops
- - NAPI?
- - wasted overhead of extra stats
- - state variables for things that are
- easily available and shouldn't be kept in card structure, cardnum, ...
- slotnumber, events, ...
- - get rid of slic_spinlock wrapper
- - volatile == bad design => bad code
- - locking too fine grained, not designed just throw more locks
- at problem
