[PATCH net-next v3 0/2] net: mana: Enforce TX SGE limit and fix error cleanup

Posted by Aditya Garg 2 months, 4 weeks 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.
