Currenty the ext_param field only distinguishes between "config change" and "vring interrupt". We can do a lot more with it though, so let's enable a full byte of possible values and constants to #defines while at it.

An Intel MIC X100 device is a PCIe form factor add-in coprocessor card based on the Intel Many Integrated Core (MIC) architecture that runs a Linux OS. It is a PCIe endpoint in a platform and therefore implements the three required standard address spaces i.e. configuration, memory and I/O. The host OS loads a device driver as is typical for PCIe devices. The card itself runs a bootstrap after
