To show the LAN performance of on-board SFP ports (X553).
FWA-2112 has 4C/8C/16C SKUs with different CPU of C3558/C3758/C3958.
C3558 supports 2 *1G SFP and 2*10G SFP+ ports from integrated X553 controller; while C3758 and C3958 supports 4 *10G SFP+ ports from integrated X553 controller.
But because the limitation of CPU (20GBs full duplex bandwidth total across all X553 ports), the throughput can't reach 100% if 4 SFP+ ports are running simultaneously on C3758/C3958 SKUs.
Here are the test results for C3758 and C3958.
