Today I checked the page for openvswitch project. It has been updated recently such that the supported arch is now limited to only arm_cortex-a9_vfpv3.
If you have the experience of using the openvswtich on openwrt, could you tell me which router model you are using?
Today I tried to refresh the package list and openvswitch is now available for both the edgerouter and asus. The package was not listed at all last week.
I guess someone has been adding this to the package list.
