[dpdk-dev] [PATCH] bus/pci: fix error in parsing vfio driver

[Wei Dai]

In pci_get_kernel_driver_by_path(), the available memory size of
dri_name should be strlen(name + 1) + 1, not the size of the
pointer (8 bytes), so "vfio-pci" is truncated to "vfio-pc"
ended with number 0.
This patch fixes it.
