The current device bind model uses /sys/bus/pci/driver/new_id scheme to bind devices to the driver. This scheme has following operations to bind a device to the driver. 1) Write device ID and vendor ID to /sys/bus/pci/driver/new_id 2) Write PCI BDF number to /sys/bus/pci/driver/bind 3) On step (1), _All_ the devices that match the device ID and vendor ID get bound to the driver 4) Except for requested devices, Unbind the remaining devices In kernels >= 3.15, An alternative scheme driver_override can be used to bind a device to driver.This scheme has following operations to bind a device to driver. 1) Write driver to /sys/bus/pci/device/driver_override 2) Write PCI BDF number to /sys/bus/pci/driver/bind This script detects the presence of /sys/bus/pci/device/driver_override, if available use optimized bind scheme to bind it Signed-off-by: Guduri Prathyusha <gprathyusha@caviumnetworks.com> Signed-off-by: Jerin Jacob <jerin.jacob@caviumnetworks.com>
