RE : [lwip-users] link down and netconn problem

[Frédéric BERNON]

I will try to find the IRC log about this discussion to know the reasons (it 
should be in my home computer). I know it was in "[task #6969] Review usage of 
conn->err in netconn layer" if it can help...

That was after a discussion with Frédéric, who did not agree that no errors are 
fatal. I think before that, we did not have non-fatal errors at all (meaning 
there were checkes for conn->err == ERR_OK at some places) and as I did not 
convince him, we added the 'fatal' check as a consensus. However, I'm still not 
totally satisfied with this solution...
