Re: [dpdk-users] Crypto QAT device not found

["Trahe, Fiona" <fiona.trahe@intel.com>]

Hi Pravin,

Good that it's working now.
Be careful of the order on changing config, this works:
1. make T=x86_64-native-linuxapp-gcc config 
2. change build/.config (if you do make T=xx config after this it overwrites your changes and reverts to the default again)
3. make
