How is it that we only provide certain basic settings,
such as IPv4 address, IPv6 address, and so on? Then,
they are not the arbitrary binary data.

Could devlink param be used for more than 4 bytes settings?
At least the IPv6 address is longer.

Besides, we need the information of SMBIOS which could
be 4K ~ 8K bytes data. Is there any way we could transmit
it to firmware?
