Subject: [ethtool] ethtool: Correct register dump offsets for Intel 82575 chipsets.

From: Matthew Vick <matthew.vick@...el.com>

When support was added to dump the registers on 82575 chipset devices,
six register offsets (receive/transmit desc length, head, and tail)
were incorrectly mapped. This patch remaps the offsets to the correct
registers.
