[dpdk-dev] [PATCH] bus/pci: fix driver name string manipulation

[Jerin Jacob]

sizeof(dri_name) is 8B on 64Bit systems.The intended operation is coping
the string after '/' from the string `name`.

This bug is not letting to probe any device string >8B hence results in
the testpmd error("No ethernet devices found) on some PMDs.
