Go bindings for DPDK

Install dpdk and dpdk-go

Setup RTE_TARGET, RTE_SDK and DPDK_VERSION in hack/dpdk.rc, then run

hack/dpdk-install.sh
source hack/dpdk-util.sh
init-dpdk`
go get -u github.com/feiskyer/dpdk-go

Notes: If dpdk is installed inside a virtual machine, (e.g. VMWARE), then patch hack/vmware.diff must be applied before compling the dpdk source.

Install dpdk-ovs

Install dpdk first, then run

hack/ovs-install.sh
source hack/dpdk-util.sh
init-dpdk
start-ovs

DPDK samples

Helloworld

go get -u github.com/feiskyer/dpdk-go/samples/helloworld

go get -u github.com/feiskyer/dpdk-go/samples/skeleton

Exception Path

Reads packets from dpdk port 0, and then write the data to tap_dpdk_00:

go get -u github.com/feiskyer/dpdk-go/samples/exception-path
exception-path

# in another terminal
tcpdump -nn -i tap_dpdk_00

Performance is not guaranteed because of less tests.
