PATCH 1/1 igb: output register's information related to RX/TX queue[4-15]

Current igb outputs registers related to TX/RX queues(ex. RDT, RDH, TDT, TDH). But it thinks the number of RX/TX queues is 4. But 82576 has 16 RX/TX queues. This patch modifies igb to output the rest of the registers if the device is 82576.
