📝 Walkthrough

Walkthrough

This pull request updates the ODROID XU4 kernel patch from version 6.6.137 to 6.6.138. The patch refines socket buffer fragment handling in both IPv4 and IPv6 network stacks: receive paths now require both absent frag lists and absent shared frags before using fallback counting, while allocation paths mark newly created buffers with the shared-fragment flag unless explicitly exempted.

Poem

A socket hops through networks free,
Its fragments marked with symmetry,
From six-three-seven up to eight,
The kernel guards each frame's true state,
On ODROID's path, so smooth and bright! 🐰✨
