From 173bebbd3b1b23b3ca598b5031ceeb88fbd68f08 Mon Sep 17 00:00:00 2001 From: Carter Chen Date: Fri, 8 Aug 2025 08:39:32 +0000 Subject: meta-facebook: yosemite4: Removed the fixed MTU 64 setting from the MCTP config # Description Fixed MCTP configuration: Changed MTU (Maximum Transmission Unit) from a fixed 68 bytes to the default setting. According to the MCTP specification, if the MTU is not explicitly set, it defaults to the MTU of the network card. # Motivation According to the DFT specification, the WF CXL update time meets the requirement of completing within five minutes. This modification reduces the CXL firmware update duration to under five minutes.
