[dpdk-dev] [PATCH] usertools: enhance device bind script module detection

[pbhagavatula at marvell.com]

From: Pavan Nikhilesh <pbhagavatula at marvell.com>

Some kernel modules have '-' in their name when populated in
'/sys/bus/pci/drivers/' where as the kernel always populates
'/sys/modules/' with '_'.
Replace '-' in module name with '_' to avoid script complaining
that module not loaded.
