Subject: [dpdk-dev] [PATCH DPDK_KMODS v7 1/2] linux/igb_uio: remove DPDK
dependency for building igb_uio

Errors-To: dev-bounces@dpdk.org
Sender: "dev" <dev-bounces@dpdk.org>
The igb_uio source code requires interrupt modes defined as
MACROS and enums in the header file rte_pci_dev_features.h.
Now, the definitions are moved to the igb_uio.c file so that
this module can be built without building DPDK
