[dpdk-users] Using l2fwd-crypto sample app

[Doherty, Declan]

Hey Surajit,

It's difficult to tell from the log output but have you actually 
installed the required libraries for the IPsec MB PMD on your system. If 
you're not sure look at the installation guide in the documentation:
http://doc.dpdk.org/guides/cryptodevs/aesni_mb.html#installation


If your interested in IPsec, you could also have a look at our IPsec 
Security Gateway sample application, which implements most of the data 
path of an IPsec security gateway, see the docs here 
http://doc.dpdk.org/guides/sample_app_ug/ipsec_secgw.html for details
