> I've seen PHY/switch/hub combinations that take longer than 30 seconds to fully negotiate the link. There is really no upper limit to the link speed/duplex/etc. negoatiation process. Even if the actual negoatiation protocol had an upper limit on negoatiation time, hardware implementations do things like try sampling the quality of the cable signal and may choose to down-rev the advertised features and restart the negoatiation. 

I do understand that some might need some longer values while some others like me really need a smaller one.

On my case, this 2mn wait breaks an hardware watchdog, so I did a small patch on my local build to get it reduced as I know  the selected value works fine for this hardware setup. And it works now perfectly.

So could it be valuable to export it as a CONFIG_something instead of patching this #define ?
