Follow-up Comment #3, bug #40303 (project lwip):
I see now. You're right, as far as I read it. It looks like xid should be
changed only on a non-retransmission of a DHCPDISCOVER. You're right too in
that it is a session id.
DHCP also won't work with multiple interfaces because xid is a global (or
function static). xid should be stored in the netif waiting to be served an
IP address. 2 netifs could be wanting a DHCP-served address on startup.
