Hi Ben:
I have read your patch about "not delete datapath flow when daemon exit". I
think this patch is really important, It can be used during upgrading without
effecting existing traffic. I have test in my env, and found it works! Thanks a
lot !
But I have a question about tunnel traffic: I have found if there're vxlan
traffic across compute nodes, when daemon exit, the traffic would breakdown.
The reason is during "close_dpif_backer" we would delete tunnel port in
datapath, so even if the flows are not delete , but as the tunnel port is
deleted , flow action turns to be "drop". So i write this mail to ask if we can
add a flag to control this behavior ?
Thanks
Timo
