Hi Pablo,
please consider these IPVS enhancements for v4.18.
* Whitepace cleanup
* Add Maglev hashing algorithm as a IPVS scheduler
Inju Song says "Implements the Google's Maglev hashing algorithm as a
IPVS scheduler. Basically it provides consistent hashing but offers some
special features about disruption and load balancing.
1) minimal disruption: when the set of destinations changes,
a connection will likely be sent to the same destination
as it was before.
2) load balancing: each destination will receive an almost
equal number of connections.

"
* Fix to correct implementation of Knuth's multiplicative hashing
which is used in sh/dh/lblc/lblcr algorithms. Instead the
implementation provided by the hash_32() macro is used.
