This way, we have a unified solution, where option bounds checking, compatibility, warnings, etc happened in one place for all three modes of input: sysfs, netlink, and module params.

Yes, I agree with you, and I will wait for you to finish the bond_option_xxx_set() and then make the bond_check_params() use them, I think the code will be more simplify.
Thanks
