Thanks for that pointer, Aaron, but it looks like swconfig won't be of use to me, because it's for configuring specific switches (my usage is not a switch - it's the Intel ethernet port directly from the Rangeley SoC).
Anyway, for now, I'm planning to write a small helper script that is invoked from from an early startup script, to invoke ethtool directly on the switch ports at startup. If I want to change the negotiation parameters, I'll have to re-invoke that script once for each change. Can't add a hotplug script for this, because those are invoked only after a successful negotiation and link sense. :-/. -----Original Message----- From: Aaron Z <aczlan+open...@gmail.com> To: Shankar Unni <shankaru...@netscape.net> Cc: OpenWrt Development List <openwrt-devel@lists.openwrt.org> Sent: Tue, Nov 11, 2014 8:21 pm Subject: Re: [OpenWrt-Devel] Configuring ethernet auto-negotiation off, setting speeds explicitly On Tue, Nov 11, 2014 at 9:09 PM, Shankar Unni <shankaru...@netscape.net> wrote: > Is there any way to disable auto-negotiation on an ethernet interface and manually set the speed and duplex parameters for it via netifd? (some equivalent of "option autonegotiate 0", etc.?) I couldn't find anything in netifd that would allow us to specify this directly. Failing this, are there any clever tricks that can allow us to do this? Have you looked into swconfig [1]? that looks like it should let you set link speeds on a per port basis.
