[lwip-users] Correctly manage cable disconnection and reconnection

[CORRADIN Michele]

Hi,
I'm new to LWIP and I'm trying to use it on a a board with an STM32F407 under 
ucOS III. I have just ported LWIP on ucOS III based on a project I found 
online, I fixed a couple of bugs and I make it running with fix IP and DHCP. 
The MAC driver is based on the ST one with some modifications for my micrel PHY.
It seems to work fine but I have some problems to correctly manage cable 
disconnection and re-connection.
Up to now I created a slow task that checks the PHY register to verify the 
connection status and if I see a cable disconnection and re-connection I 
restart the phi init in order to correctly set speed, .. but it's not clear to 
me what I should do to "re-init" LWIP.
Un to now I'm doing nothnig and it seems it work 80% of the time .. but 
sometimes it seems it's not able to correctly restart.
I'm just trying with a ping to see what happens.
thanks for the support
michele
