As this increases the performance by improving the linear search function, I was wondering if a similar ranking is implemented within the kernel datapath as well. I wasn't able to find the relevant source code for it, if possible can someone point me towards it (if the ranking is implemented at all in this case)?
Hi Vipul,
No, this feature is not implemented in kernel datapath.
