[igb] Add igb driver

This commit adds an igb (Intel GigaBit) driver based on Intel source
code available at:

    http://sourceforge.net/projects/e1000/

which is upstream source for the Linux kernel e1000 drivers, and
should support some PCIe e1000 variants.

+ *      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);
