My question is that an Ethernet frame won't be bigger than 1500 bytes [correct?]
Incorrect. 10G and faster ethernet support jumbograms. We run our HPC 10G network with an MTU of 9000 (which is 2 pages and a bit more).
Ok. So in any case the driver won't poke past ethernet header to look for the size [Correct?]. So it means only when MTU is bigger than page size would there be a possibility of skb_frags [Correct?].
