The firmwares and the following changelog are from the "Chelsio Unified
Wire v3.15.0.0 for Linux."

Date    : 09/24/2021
====================

FIXES
-----

BASE:
- Added support for SFP+ RJ45 (0x1C).
- Fixing backward compatibility issue with older drivers when multiple
  speeds are passed to firmware.

OFLD:
- Do not touch tp_plen_max if driver is supplying tp_plen_max. This
  fixes a connection reset issue in iscsi.
