From d8f1fa1e382050139006e0f03000275e639d09fe Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Thu, 3 Jan 2013 01:58:01 +0000 Subject: [PATCH] switch: ROBO Switch Gigabit MII Support I wrote this patch some time ago because I had a need for one of the Gigabit ports (Linksys E3000) to be forced to 100FD. This is based on the robocfg sources included w/ the RT-N16 sources from ASUS. Since work is progressing on a BGMAC driver that could be included in OpenWRT, this may be useful to someone else. In testing, forcing the speed to 10/100 or 1000 worked fine; however, when trying to force full-duplex mode, the result was always half-duplex. I was not able to isolate the source of the problem (this patch, driver or H/W limitation). The only way I could get it to work was to set the port to Auto, but then only advertise 100FD (not included in this patch). I have a modified version of the robocfg package as well, I'd have to clean it up a little first (remove the full-duplex hack) before submitting it if there is interest.
