[OpenWrt-Devel] Openvswitch package not available in trunk

Wed Aug 19 08:38:46 EDT 2015

OVS seems to work fine if I compile it with uClibc instead of musl
On x86 (kernel 4.1 added manually) + uClibc + OVS 2.4 it works fine
On x86 (kernel 4.1 added manually) + musl + OVS 2.4 it seems to segfault

Will keep looking.
