The drivers need to implement all of those hooks. It wouldn't be that hard to reimplement. The drivers would have to reimplement it anyway - they'd have to implement the generic set of standard statistics, then export driver-specific things. You know, the stuff our drivers already expose via sysctl. adrian On 26 June 2013 17:02, Jack Vogel wrote: > ethtool is GPL so I wouldn't expect it to show up around here :) > > Implementing something like it for FreeBSD would be cool however, sometimes > sysctl just > seems clunky although its usually how i cope with driver things that might > be changed via > ethtool in Linux.
