Why not simply make it unsigned so that it follows the native processor
register size for the given platform? Isn't a system really constrained on
memory more likely to have sizeof(unsigned) == sizeof(u16_t) anyway?

Is it really any more efficient to call tcp_write once with a large block of
data versus letting the stack call back to tcp_sent a couple or few times?
