Hi Everyone:
For running ovs on Android phone, so far i have installed openvswitch_mod.ko
on Android kernel and cross compiled ovs-dpctl.
It seems they work on Android:
1. I can create a datapath dp0
2. i can add phone's wifi interface (tiwlan0) to the dp0
the following is the dp0 status:
# ./ovs-dpctl show
system@dp0:
flows: cur:0, soft-max:1024, hard-max:1048576
ports: cur:2, max:1024
groups: max:16
lookups: frags:0, hit:0, missed:4, lost:0
queues: max-miss:100, max-action:100
port 0: dp0 (internal)
port 1: tiwlan0

Jan 28 01:48:39|00005|dpif_linux|WARN|/dev/net/dp46388 is device 248:4 but
should be 248:5, fixing
But i don't know reason of the dpif_linux WARN message, and is it a
potential problem, how to fix it?
Does anyone has some ideas?
Thanks
