In-between the MAC & PHY there can be a mode converter, which converts one
mode to another (e.g. GMII-to-RGMII).

The converter, can be passive (i.e. no driver or OS/SW information
required), so the MAC & PHY need to be configured differently.

For the `stmmac` driver, this is implemented via a `mac-mode` property in
the device-tree, which configures the MAC into a certain mode, and for the
PHY a `phy_interface` field will hold the mode of the PHY. The mode of the
PHY will be passed to the PHY and from there-on it work in a different
mode. If unspecified, the default `phy-mode` will be used for both.

The firmware reset and loading policies can be controlled with the
combination of three hwinfo keys, 'abi_drv_reset', 'abi_drv_load_ifc'
and 'app_fw_from_flash'.

'app_fw_from_flash' defines which firmware should take precedence,
'Disk', 'Flash' or the 'Preferred' firmware. When 'Preferred'
is selected, the management firmware makes the decision on which
firmware will be loaded by comparing versions of the flash firmware
and the host supplied firmware.

'abi_drv_reset' defines when the driver should reset the firmware when
the driver is probed, either 'Disk' if firmware was found on disk,
'Always' reset or 'Never' reset. Note that the device is always reset
on driver unload if firmware was loaded when the driver was probed.

'abi_drv_load_ifc' defines a list of PF devices allowed to load FW on
the device.

Furthermore, we limit the cases to where the driver will unload firmware
again when the driver is removed to only when firmware was loaded by the
driver and only if this particular device was the only one that could
have loaded firmware. This is needed to avoid firmware being removed
while in use on multi-host platforms.

There are cases where we want to read a hwinfo entry from the NFP, and
if it doesn't exist, use a default value instead.

To support this, we must silence warning/error messages when the hwinfo
entry doesn't exist since this is a valid use case. The NSP command
structure provides the ability to silence command errors, in which case
the caller should log any command errors appropriately. Protocol errors
are unaffected by this.
