[lwip-devel] [bug #27445] PCB hangs in Fast Retransmit due to unchanging cwnd

[Bill Auerbach]

Follow-up Comment #8, bug #27445 (project lwip):

Then you want:

if ((u16_t)(pcb->cwnd + pcb->mss) < pcb->cwnd) { ... }

If you add something to cwnd and it became less than the original cwnd, then
it overflowed, right?

The initial point that I was trying to show is that the cast is meaningless
and doesn't add anything.

Bill
