Zynq Ethernet Performance 2015.4

XAPP1082 v4.0 2015.4
This wiki page summarizes the performance of PS-EMIO (MACB diver) and PL Ethernet with CSO support for 1000BaseX and SGMII.
Build:
Vivado 2015.4
Kernel version 4.0 (2015.4)

These measurements are obtained against u-buntu high performance peer machine. The NIC on motherboard has been used with default offload options
(GSO, TSO) enabled. Performance is expected to differ when a different peer OS is used and peer NIC offload options are disabled.
Socket size in netperf (-s) is configured to 65536 for inbound tests.
