Most processors with integrated 100Mbit MAC supports scatter-gather.
Not really a noteworthy feature unless it supports some more advanced

Well, I do think simple scatter/gather is a worthy feature for TX since lwIP can create pbuf queues that then don't have to be memcpy'd before sending. I'd say automatic length detection is 'nice-to-have' as a speedup, but 2-byte alignmen instertion after the MAC header often also does the trick
