Related to this is the question of what ports are even on for various ports.
I don't believe it's possible today to list what features are on for what ports. At least not without a lot of emailing... Before designing a finer-granularity on/off switch, it seems it might make sense to have a global view of who's using what (and ideally why?). -eric On Mon, Feb 13, 2012 at 3:13 PM, Adam Barth <[email protected]> wrote: > On Mon, Feb 13, 2012 at 1:02 PM, Maciej Stachowiak <[email protected]> wrote: >> >> On Feb 10, 2012, at 4:09 PM, Ryosuke Niwa wrote: >> >>> Hi all, >>> >>> In general, the decision of whether a given feature is enabled or not is >>> made by each port.
