A config option is added to disable caching of dynamic entries like SQEs and stack pages. Also locks down all HW contexts in NDC, preventing them from being evicted. This option is useful when the queue count is large and there are huge NDC cache misses. It's trade off between SQ context misses and dynamically changing entries like SQE and stack page pointers.

This config option disables caching of dynamic entries such as NIX SQEs
|
|
, NPA stack pages etc in NDC. Also locks down NIX SQ/CQ/RQ/RSS and
|
|
NPA Aura/Pool contexts.
