Description Peter Robinson 2016-04-12 09:05:28 UTC 
On aarch64/Power64 it seems tcp fastopen isn't properly detected. All the builders for these arches are running Fedora 23 with a 4.4.x kernel. This kernel feature was enabled by default from 3.13 [1]. Seems a regression/change in 2.9.3 as it built OK in older versions.

This bug appears to have been reported against 'rawhide' during the Fedora 25 development cycle.
Changing version to '25'.
