Are those CPB / PRD structs endian-safe when using a big-endian CPU?
Cheers
They should be, I believe cpu_to_leXX is used whenever the multi-byte
elements are being written.
I was thinking more about the non wordsized fields,
such as the various u8 bytes that gcc will lay out differently
depending upon endianess.
