Re: [lwip-users] HTTP client with raw tcp

Having done some more debugging it appears that somewhere between the
successful DHCP negotiation completing and calling tcp_connect() that
something is modifying the contents of the netif -> state entry.

At the point my low_level_output() function is being called the name[0],
name[1] and num fields are still correct but I use "state" to point to a
structure that contains information the hardware interface needs and when
tcp_connect() propagates down through the IP layer and into ARP and down it
is incorrect.

I can't see anything obvious in the lwIP code that would corrupt this.
Anyone any ideas?

Thanks,

Andy.
