From: Jeb Cramer <[EMAIL PROTECTED]>
This introduces the new internal API for hardware-specific code. The
code is split up per chipset and allows future chipset support to be
added without touching the run-time codepatch of old hardware, greatly
reducing the risk of introducing regressions, and making debugging far
easier due to greater codepath separation.
The API code sets up function pointers for the main hardware specific
routines for each family and initializes the MAC type at load time. From
there on the driver initializes each subcomponent (PHY, NVM, etc.) through
it's function pointer call.

+ *
+ * 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;
