+Usage:
+------
+
+ %(argv0)s [options] DEVICE1 DEVICE2 ....
+
+where DEVICE1, DEVICE2 etc, are specified via PCI "domain:bus:slot.func" syntax
+or "bus:slot.func" syntax. For devices bound to Linux kernel drivers, they may
+also be referred to by Linux interface name e.g. eth0, eth1, em0, em1, etc.
+
+Options:
+ --help, --usage:
+ Display usage information and quit
+
+ -s, --status:
+ Print the current status of all known network, crypto, event
+ and mempool devices.
+ For each device, it displays the PCI domain, bus, slot and function,
+ along with a text description of the device. Depending upon whether the
+ device is being used by a kernel driver, the igb_uio driver, or no
+ driver, other relevant information will be displayed:
+ * the Linux interface name e.g. if=eth0
+ * the driver being used e.g. drv=igb_uio
+ * any suitable drivers not currently using that device
+ e.g. unused=igb_uio
+ NOTE: if this flag is passed along with a bind/unbind option, the
+ status display will always occur after the other operations have taken
+ place.
+
+ --status-dev:
+ Print the status of given device group. Supported device groups are:
+ "net", "baseband", "crypto", "event", "mempool" and "compress"
+
+ -b driver, --bind=driver:
+ Select the driver to use or \"none\" to unbind the device
+
+ -u, --unbind:
+ Unbind a device (Equivalent to \"-b none\")
+
+ --force:
+ By default, network devices which are used by Linux - as indicated by
+ having routes in the routing table - cannot be modified. Using the
+ --force flag overrides this behavior, allowing active links to be
+ forcibly unbound.
+ WARNING: This can lead to loss of network connection and should be used
+ with caution.
+
+Examples:
+---------
+
+To display current device status:
+ %(argv0)s --status
+
+To display current network device status:
+ %(argv0)s --status-dev net
+
+To bind eth1 from the current driver and move to use igb_uio
+ %(argv0)s --bind=igb_uio eth1
+
+To unbind 0000:01:00.0 from using any driver
+ %(argv0)s -u 0000:01:00.0
