Hello all,
I am new to DPDK. I want to try out on a laptop with an unsupported NIC.
(linux ubuntu 16.04)
What are the best ways of doing this ? Are there any existing examples that
address this use case?
If possible I would like to be doing my development on a laptop entirely
and move my work to a desktop with a supported NIC at a later date when I
am able to purchase a proper system.
I am hoping migrating my application from laptop environment to final
target will not involve a lot of changes other than new NIC configuration.
Thank you,
DPDK new user !!

VMWare or VirtualBox VM w/ Intel E1000 emulation.
I use it for development all the time.
It's not incredibly amazing but it works fine.

E1000 emulation is often problematic for DPDK. VMWare's emulation of PCI bus
does not handle interrupts correctly.
Use virtual NIC's (vmxnet3 and virtio) if at all possible.

vmxnet3 and virtio-net support in DPDK are both broken in VirtualBox. I
usually use VirtualBox instead of VMWare because it doesn't require license
fees. Since none of this is covered in the documentation or on the roadmap to
get fixed in the DPDK virtio-net PMD, it would be difficult for us users to
know about it. But thanks for pointing it out.
Matthew.

In the beginning was the lambda, and the lambda was with Emacs, and Emacs

Sometimes your development system is a MacBook Pro.
