I am trying multi-segment mbuf, but it seems not working. On my target host, the mbuf size is set to 2048 and I am trying to send large packet to it (say 2500 bytes without fragmentation) from another host. I enabled both jumbo_frame and enable_scatter for the port. But I saw on the target only one mbuf is received with data_len equal to 2500 (it's supposed to be a two-mbuf chain). Although mbuf itself is not working as expected, ping between two hosts succeeded (large ping size; no fragmentation).
1. my mbuf size is only 2048. how can it support receiving such large packet in one mbuf? 2.how to make it work as expected (enable multi-segment mbuf and receive using mbuf chain when needed)? Appreciate your help.
