Subject: [PATCH 1/2] net: macb: Remove unnecessary alignment check for TSO
Date: Fri, 31 Jan 2020 15:57:34 +0530 [thread overview]
Message-ID: <1580466455-27288-2-git-send-email-harini.katakam@xilinx.com> (raw)
In-Reply-To: <1580466455-27288-1-git-send-email-harini.katakam@xilinx.com>
The IP TSO implementation does NOT require the length to be a
multiple of 8. That is only a requirement for UFO as per IP
documentation.
