- In case of whitelist sub-device probed by EAL, fail-safe PMD will take the device
- as is, which means that EAL device options are taken in this case.
- When trying to use a PCI device automatically probed in blacklist mode,
- the syntax for the fail-safe must be with the full PCI id:
- Domain:Bus:Device.Function. See the usage example section.
+ In case where the sub-device is also used as an allowed device, using ``-a``
+ on the EAL command line, the fail-safe PMD will use the device with the
+ options provided to the EAL instead of its own parameters.
+
+ When trying to use a PCI device automatically probed by the command line,
+ the name for the fail-safe sub-device must be the full PCI id:
+ Domain:Bus:Device.Function, *i.e.* ``00:00:00.0`` instead of ``00:00.0``,
+ as the second form is historically accepted by the DPDK.
