[PATCH net] net: rmnet: Fix checksum offload header v5 and aggregation packet formatting

From: Bagas Sanjaya

Date: Wed Oct 15 2025 - 05:25:57 EST


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")
