This change introduces a split to the Intel E1000 driver, now rather than

Browse Source 
just em, there is an igb driver (this follows behavior with our Linux drivers).
All adapters up to the 82575 are supported in em, and new client/desktop support
will continue to be in that adapter.

The igb driver is for new server NICs like the 82575 and its followons.
Advanced features for virtualization and performance will be in this driver.

Also, both drivers now have shared code that is up to the latest we have
released. Some stylistic changes as well.

Enjoy :)

/*
* TBI_ACCEPT macro definition:
*
* This macro requires:
* adapter = a pointer to struct e1000_hw
* status = the 8 bit status field of the Rx descriptor with EOP set
* error = the 8 bit error field of the Rx descriptor with EOP set
* length = the sum of all the length fields of the Rx descriptors that
* make up the current frame
* last_byte = the last byte of the frame DMAed by the hardware
* max_frame_length = the maximum frame length we want to accept.
* min_frame_length = the minimum frame length we want to accept.
*
* This macro is a conditional that should be used in the interrupt
* handler's Rx processing routine when RxErrors have been detected.
*
* Typical use:
* ...
* if (TBI_ACCEPT) {
* accept_frame = TRUE;
* e1000_tbi_adjust_stats(adapter, MacAddress);
* frame_length--;
* } else {
* accept_frame = FALSE;
* }
* ...
