SRU Justification

[Impact]

* Microsoft requested patches to implement variable-sized MANA indirection tables on Noble and Jammy releases

[Fix]

* 1 backport from upstream, 7fc45cb68696: "net: mana: Allow variable size indirection table"

[Test Plan]

* Compile tested
* Will be further tested by Microsoft

[Regression potential]

* Changes are largely localized to MANA.
* If indirection table is not properly managed, it could lead to memory management issues (null pointer, double free, etc...)

[Other info]

* SF#00407396
