- Add the RX refresh changes from igb to ixgbe
- Also a couple minor tweaks to the TX code from the same source.
- Add the INET ioctl code which has been missing from this driver,
and which caused IP aliases to reset the interface.
- Last, some minor logic changes that just reflect upcoming
hardware support, but have no other functional effect now.
