DPDK kernel config

[chris_boger]

I'm attempting to run the ipsec-secgw example on an LS1046afrwy with LSDK 2004, but having trouble understanding the kernel prerequisites.

Using default kernel config and fsl-ls1046a-frwy-sdk.dtb, I can see eth0-eth3 available to the kernel. When I switch to  fsl-ls1046a-frwy-usdpaa.dtb, I lose my kernel network devices and sadly I also have no network devices listed by dpdk-devbind.py --status. This makes me think my kernel config is wrong. 

Which configuration settings are relevant to enabling DPDK apps?

Please use the default kernel configuration and dts file fsl-ls1046a-frwy-usdpaa.dtb to run DPDK application.

Using fsl-ls1046a-frwy-usdpaa.dtb, all Ethernet interfaces will be assigned to DPDK, so you cannot see any Ethernet interface in Linux.
