We're rolling it into the PCBSD rolling update as well. I'm thinking it makes sense to roll this into the 9.2 release to give us more scalability. -Alfred On 7/7/13 1:34 AM, Andre Oppermann wrote: > On 07.07.2013 08:32, Alfred Perlstein wrote: >> Andre, >> >> Are you going to have time to MFC things from -current for >> auto-tuning -stable before 9.2? > > I simply ran out of time on Friday and MFCing such a big change requires > more testing. > >> I fear (maybe unnecessarily?) that we are about to ship yet another >> release that can't do basic >> 10gigE when sufficient memory exists. > > There was some debate with myself whether such a behavior changing MFC > would be appropriate for a mid-stream stable release.
