Hello folks, I'm using the code below to retrieve configuration data for my vDPA file via ioctl. I get as output: Configuration data (24 bytes): 5a c3 5f 68 48 a9 01 00 08 00 dc 05 00 00 00 00 00 00 00 00 00 00 00 00 ASCII representation: Z._hH................... Could a good Samaritan point me in the right direction for the docs I need to understand these values and convert them to a human-readable format? hank you in advance!
