VF BARs shall only support 32-bit and 64-bit memory space. PCI I/O Space is not supported in VFs. Bit 0 of any implemented VF BARx must be RO 0b except for a VF BARx used to map the upper 32 bits of a 64-bit memory VF BAR pair. The alignment requirement and size read is ...

When the message packet is large, the encapsulation of the message body should be considered. Simple JSON encapsulation is not efficient in message parsing, so we should consider using Avro, protobuf and other encoding formats for Payload format encapsulation. ...
