Important:
The DFI FS700 Series Qseven module provides Gigabit Ethernet with one Atheros
AR8033 Ethernet PHY. The maximum throughput that the Gigabit Ethernet performs is
limited to 470Mbps (total for Tx and Rx) due to internal bus limitations based on Fre-
escale’s Errata ERR004512. The actual measurement of the Gigabit Ethernet controller
used on the FS700 Series system board is up to 380Mbps. This difference might be
caused by the software configuration, network environment or equipment.
