Problem with building openwrt .bin

[peterrz]

Hi,
I have problem with size of openwrt .bin
Your requirement are too big even i remove many default packages. My question is why we need openvswitch-ipsec (options) ?! Openvswitch isn't enough?! You earlier mention it 'install openvswitch modules and requirements:

Network   /   openvswitchswitch
          /   openvswitch-ipsec'

Cuase openvswitch-ipsec need many requirements library.
I see start.sh just building openvswitch bridge to connect controller and click ap and also data link.
Can it be done with openvswitch only?
