Replying to myself, because I don't think this is a lwip problem.
Receive counter lwip_stats.link also suggests the packet is missing,
so the problem is very likely in driver.
Anyone has a nice lpc23xx emac source? ;-)
Thank you for getting me unstuck after a couple of days!
And sorry for the noise!
