Bug Description
SRU Justification
[Impact]
* Microsoft requested patch to improve RX buffer handling in MANA driver. Previously reverted as part of LP: #2131828, this patch looks to reintroduce the proper functionality with added fix.
[Fix]
* Jammy: backports of the following patches:
- 1705341485ff: "net: mana: Improve mana_set_channels() in low mem conditions" upstream
- 730ff06d3f5c: "net: mana: Use page pool fragments for RX buffers instead of full pages to improve memory efficiency." from linux-next
[Test Plan]
* Compile tested
* Microsoft tested
[Regression potential]
* Changes are localized to MANA. Possible regressions could result in unexpected behavior of MANA driver.
