From 5a8a163ac394d9f4f7ff57f415d82bd673b0068c Mon Sep 17 00:00:00 2001 From: Andy Fleming Date: Sun, 31 Aug 2008 16:33:30 -0500 Subject: Add pixis_set_sgmii command The 8544DS and 8572DS platforms support an optional SGMII riser card to expose ethernet over an SGMII interface. Once the card is in, it is also necessary to configure the board such that it uses the card, rather than the on-board ethernet ports. This can either be done by flipping dip switches on the motherboard, or by modifying registers in the pixis. Either way requires a reboot. This adds a command to allow users to choose which ports are routed through the SGMII card, and which through the onboard ports. It also allows users to revert to the current switch settings. This code does not work on the 8572, as the PIXIS is different.
