Subject: [dpdk-dev] [PATCH v2 23/23] doc: update mlx4 documentation following MOFED 3.0 changes
Date: Tue, 30 Jun 2015 11:28:09 +0200 [thread overview]
Message-ID: <1435656489-27986-24-git-send-email-adrien.mazarguil@6wind.com> (raw)
In-Reply-To: <1435656489-27986-1-git-send-email-adrien.mazarguil@6wind.com>
- Add RX/TX L3/L4 checksum offloading and validation.
- Update kernel module parameters section.
- Update prerequisites for MOFED and firmware versions.
- Remove optimized external libraries section. MOFED now provides enhanced
support directly without having to install modified libraries.
