[dpdk-dev] [prefix=DPDK_KMODS v6 1/2] linux/igb_uio: remove DPDK dependency for building igb_uio

[Thomas Monjalon]

> 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

Useless comment, creating a barrier between previous comment
and definitions. Please remove.

I would remove the above blank lines to make clear what is from rte_pci_dev_features.h.
