Subject: [PATCH net-next v4 0/2] net: mana: Enforce TX SGE limit and fix error cleanup
Date: Wed, 12 Nov 2025 05:01:44 -0800 [thread overview]
Message-ID: <1762952506-23593-1-git-send-email-gargaditya@linux.microsoft.com> (raw)
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 v4:
* Fix warning during build reported by kernel test robot
