Is there a way to have the test verify element size. I'm not that familiar with YNL.
I suspect the reaction may be because drivers often use a smaller type. But at the uAPI level the indirection table has always been represented as an array of u32 (I mean the ioctl). And in the core we also always deal with u32s. The Netlink type is not allowed to change either (it's a "C array" not individual attributes so members must be known size).
LMK if you want me to add an assert or rework this. We could technically keep the rsp struct around and use it directly?
Not fully convinced it's worth a respin, but LMK.. :)
Not at all. Thanks for that uAPI context.
