[dpdk-dev] [PATCH] usertools: Fix clearing any old data

[Timothy Redaelli]

Currently clear_data (dpdk-devbind.py) doesn't work as expected since
"global devices" is missing and so "devices" is considered a local variable.

This commit changes "clear_data" function in order to really clear
devices by adding "global devices".
