[PATCH net-next v6 0/2] net: mana: Enforce TX SGE limit and fix error cleanup

Posted by Aditya Garg 1 week, 6 days ago

Add pre-transmission checks to block SKBs that exceed the hardware's SGE
limit. Force software segmentation for GSO traffic and linearize non-GSO
packets as needed.

Update TX error handling to drop failed SKBs and unmap resources
immediately.

---
Changes in v6:
* Replace #if logic with constant expression in if().

Changes in v5:
* Drop skb_is_gso() check for disabling GSO in mana_features_check().
* Register .ndo_features_check conditionally to avoid unnecessary call.

Changes in v4:
* Fix warning during build reported by kernel test robot
