Backport of #18826
Contribution description
This fixes the off-by-one error in SLIP the same way as it was fixed in ethos.
Previously I tried to make SLIP use the chunked ringbuffer to handle this with common code or clean up the driver while fixing the bug, but neither reached consensus.
So this minimal solution should fix the bug while not touching the driver otherwise.
