Adds support for booting from remote volumes to ``irmc-virtual-media``
boot interface. It enables boot configuration for iSCSI or FibreChannel
via out-of-band network.
In addition to the same configuration as generic boot-from-volume, this
interface requires the following settings.
* It is necessary to set a physical port ID to network ports and volume
connectors. All cards including those not used for volume boot should be
registered.
* A physical ID format is: ``<Card Type><Slot No>-<Port No>``
``<Card Type>``
LAN, FC or CNA
``<Slot No>``
0 indicates onboard slot. Use 1 to 9 for addon slots.
``<Port No>``
A port number starting from 1.
* Set the IDs to ``node.driver_info.pci_physical_ids``. This parameter
is a list of pair of UUID of a resource (Port or Volume connector)
and a physical ID like:
pci_physical_ids = 1ecd14ee-c191-4007-8413-16bb5d5a73a2:LAN0-1,1ecd14ee-c191-4007-8413-16bb5d5a73a2:CNA1-1
* For iSCSI, volume connectors with both type ``iqn`` and ``ip`` are
required. The configuration with DHCP is not supported yet.
* For iSCSI, a subnet mask of the storage network is necessary. It should
be set to ``node.driver_info.storage_network_size`` as integer.
This feature requires specific FC cards or CNAs (Converged Network Adapter).
See the documentation of iRMC driver for details.
