Currently the driver uses advanced descriptors for its main functionality,
but then uses legacy when testing. This patch changes this so that
advanced descriptors are used throughout and all mentions of legacy
descriptors are removed.

IP Checksum enable doesn't need packet split in order to function. It only
requires the use of advanced descriptors which the current igb driver does.
So we can enable it always without any issues.

This patch:
- increases the precision of the receive/transmit interrupt
coalescing register value computations by using 64bit temporaries;
- adds functions to read the current hardware coalescing register
values and convert them back to usecs;
- exports the {get,set} {rx,tx} coal methods via the standard
ethtool coalescing interface.

which are willing to take the risk, it is optional and can be disabled by
