The function "next_fn()" seems to provide the next valid function. Therefore, if the current function is 0 (fn = 0), then the next valid function will be 1 which is returned by next_fn(). It extends similarly until the case where current function is 6 (fn = 6) which shall return the next valid function as 7. So all 8 PFs are still treated as valid and there doesn't seem to be any limitation. Only in the case where the EP doesn't support ARI (there is no function 8 (fn = 8)), the call to next_fn() with the fn parameter set to 7, will return -ENODEV which seems to be the expected behavior.
Regards, Siddharth.
yes, you are right, the fn 7 has no next_fn, hence should return - ENODEV.
ignore this patch!
