Some stats are fetched via slow firmware mailbox, which can cause
packet drops under heavy load. So, this series removes these stats
from ethtool -S and expose them via debugfs.

Patch 1 removes stats fetched via firmware from ethtool -S.
Patch 2 exposes stats removed in Patch 1 via debugfs.

Thanks,
Rahul
