Merge branch 'net-mana-enforce-tx-sge-limit-and-fix-error-cleanup'

Aditya Garg says:

====================
net: mana: Enforce TX SGE limit and fix error cleanup

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.
