Hi Gert,
thanks for your reply
>>as our way to do --daemon wasn't compatible with cryptodev...do you mean it 
>>is suggested in daemon mode when running openvpn with cryptodev?
also, i found some post said the Openvpn support cryptodev is not good, as 
Openvpn need do lot of job copy data to/from user space to kernel, "Hoewever 
the user-to-kernel and kernel-to-user copying of packets (context switches) is 
the bottleneck. The OpenVPN speed gets capped long before the crypto accel 
would make a difference. Its only useful for pure Kernel based VPNs like IPSec 
or L2TP." (source https://forum.openwrt.org/viewtopic.php?id=19586) 
Thank you.
