Will this be compatible with all kernel versions that has 1 RSS table?

Is this related to the kernel version, kernel driver version or musdk version?

[L.H.] yes

Is this related to the kernel version, kernel driver version or musdk version?
[L.H.] it is related to the pp2 kernel driver version which bounds to a kernel version
