Details:

The new functions for using static messages from interrupt handlers has a
problem with the message type.  When calling tcpip_callbackmsg_new() the
function sets the message type to TCPIP_MSG_CALLBACK which would cause the
tcpip_thread() function to free the message after the callback.  This is not
the intended behaviour, the message structure should not be deleted.

Line 419 in tcpip.c should be:

msg->type = TCPIP_MSG_CALLBACK_STATIC;
