Thanks,

I'm not sure why use 2048 for some NICs. Anybody known about this?
Scatter feature is used when received packets over the size of mbuf.
I think 1024 and 2048 should be the same to measure this feature.

I am not sure why too,but test_plan_scatter may give us some inofmation:
Configuring the size of mbuf data buffers
=========================================
The default size of the mbuf data buffer is 2048 so that a full 1518-byte
(CRC included) Ethernet frame can be stored in a mono-segment packet.
