The purpose of this changes was to fix a bug: when DPDK app crashes, those devices by igb_uio are not stopped either DPDK PMD driver or igb_uio driver. Then it has been pointed out by Stephen Hemminger that it has backward compatibility issue: cannot run old version DPDK on modified igb_uio. However, we still have not figure out a new way to fix this bug without this change. Let's postpone this deprecation announcement in case this change cannot be avoided.
