Subject: [PATCH net] net: rmnet: Fix checksum offload header v5 and aggregation packet formatting
Date: Wed, 15 Oct 2025 16:25:41 +0700 [thread overview]
Message-ID: <20251015092540.32282-2-bagasdotme@gmail.com> (raw)
Packet format for checksum offload header v5 and aggregation, and header
type table for the former, are shown in normal paragraphs instead.
Use appropriate markup.
Fixes: 710b797cf61b ("docs: networking: Add documentation for MAPv5")
Fixes: ceed73a2cf4a ("drivers: net: ethernet: qualcomm: rmnet: Initial implementation")
