Hi Dave,

I've been looking into your request number 2 above (as a reminder, it had to do with a patch I submitted that added a module parameter to e1000e in order to enable/disable Energy Efficient Ethernet for a particular type of adapter).

For this new ethtool feature bit/flag for EEE, would you prefer it be set via:
1) the generic parameter setting option (e.g. -s ethX [eee on|off]),
2) yet another new show/change option pair, or
3) a new option that can set this new feature and be expandable to future features that are likewise not related to existing ethtool options (e.g. -F [eee on|off] [whizbang on|off])?

For #2 or #3, it makes sense to use ethtool_op_[g|s]et_flags with new ETH_FLAG_<feature> and NETIF_F_<feature> defines, but #1 can be implemented that way or by using remaining reserved elements of struct ethtool_cmd - if your preference is for #1, would you prefer it be implemented with the former or latter?

Thanks,
Bruce.
