RFC: Ethtool patches to add multi queue support, LRO

All,

Recently new features have been written to add multiqueue support and LRO. However, none of the patches touch on a basic configuration scheme and most use module parameters.

I propose several patches to add support to change these features for LRO and multiqueue. Currently these patches are implemented in the most generic way possible (largely copy/paste from current ethtool code) - and add 'ethtool -k lro on|off' support that toggles the NETIF_F_LRO generic device flag, and a new ethtool_queueparam struct to get/pass rx and tx queue count.

I'm contenplating adding a "usecs-irq" non-rx non-tx parameter for the intel (1/10) gigabit adapters since our adapters share an interrupt moderation counters for both rx and tx, but that will come later.

Cheers,

Auke
