[SRU][F:linux-bluefield][PATCH] net/sched: act_ct: Offload only ASSURED connections

[Bodong Wang]

From: Chris Mi <cmi at nvidia.com>

BugLink: https://bugs.launchpad.net/bugs/1961819

Short-lived connections increase the insertion rate requirements,
fill the offload table and provide very limited offload value since
they process a very small amount of packets. The ct ASSURED flag is
designed to filter short-lived connections for early expiration.

Offload connections when they are ESTABLISHED and ASSURED.
