[ECOS] ethernet driver without link...

[Stefan Sommerfeld]

Hi,

I currently working on a correct 'link' detection for the lan91cxx driver, 
but how is the best way to implement this feature? Currently the only good 
solution is to check for the link in init() and return false if there's no 
valid link, but this means there's no network at all. I think the best way 
would be to simply report an error and all accesses return quick until a 
valid link is detected. The RedBoot tries to get it's network address 
(dhcp) over and over again with multiple timeout even if i always return 
false in the can_send() function.

Bye....
