GetRSSCPUCore() now works correctly for N cores (where N is not 2 ^ n) with i40e (e.g., XL710)
-> the functions from the RSS hash value to the Rx queue number are different between NICs
1) ixgbe (e.g., X520): (Rx queue number) = (7 LS bits of RSS hash value) mod N
* See Section 7.1.2.8 of https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/82599-10-gbe-controller-datasheet.pdf
2) i40e (e.g., XL710): (Rx queue number) = (9 LS bits of RSS hash value) mod N
* See Section 7.1.8 of https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/xl710-10-40-controller-datasheet.pdf
-> fixed the GetRSSCPUCore() to handle each case correctly

- Reducing scope of events
--> Ack goes to YoungGyoun
- Stats bug that does not appear in kernel version <= 4.1.. but appears in linux-4.4.
--> Always, always do copy_from_user() for user-space buffers before accessing
them in kernel module. This one was hard to catch!
--> Ack to Jaehyong for initially reporting the problem.
