Paul and others,
I've forwarded this request to SSH's IPR lawyer.

FYI, I was told about the existece of IPR that looks like it could be
matching some of the proposed solution on handling ESP with multiple CPUs.

The invention may be utilised where anti-replay protection is
required for packet flows, such as those using the IPSec protocol.
A bit pattern from the flow identifier may be utilised to split
the received packets between various separate packet processing
entities. Each processing entity then examines a specific quantity
of the least significant bits of the sequence number to determine
whether a packet has arrived out of sequence. The flow identifier
may be derived as a function of the Security Parameters Index
(SPI) of an Encapsulating Security Payload (ESP) header and the
relevant sequence number within that header. The flow identifier
may then act as an effective SPI and may occupy the field normally
reserved for the SPI.

Perhaps someone can reach out to SSH Communications and see about
submitting any license terms that are acceptable for standards track
IETF documents? Or alternatively share some prior art to the list for
this patent (granted in 2018)
