= Newport Ethernet [[PageOutline]] Newport supports 1GbE.

The GW6404 has 2x SFP sockets shared with eth2/eth3 [=#a10gbe] == 10GbE == The OcteonTX SERDES lane can support up to 10GbE total but that would mean only having 1 enet (SFP) port. We chose to route 1GbE to multiple ports and selected PHYs to match. Routing 10GbE would be a custom board design with a minimum order quantity and NRE design fees. The SERDES lane off the CPU can support 10GbE TOTAL this could be the following configurations: * 1x 10GbE * 2x 5GbE * 4x 2.5GbE [=#sfp] == SFP (Small form-factor pluggable transceiver) support The GW6404 has 2x SFP sockets that are shared with J22 ETH3/4 connectors (vnic2/vnic3 in U-Boot eth2/eth3 in Linux). The SFP sockets support up to 1Gbps !SerDes however some software support is required. Please contact sales@gateworks.com if you wish to use SFP and provide us details of the SFP module you wish to use. Any SFP module that advertises 1000Base-SX, 1000Base-LX, 1000Base-T capability should be supported. Validated with: * Addon MGBSX1-AO (1000BASE-SX Duplex 850NM / 550M LC) * Addon EX-SFP-1GE-T-AO (1000BaseT Copper) === Software A software driver is required on the host to detect insertion and removal of SFP modules, query the capabilities of the SFP via its MSA, verify compatibility and configure the PHY for compatibility. Additional Software support required: * BDK boot time configuration: - add SFP detection and VSC8574 QSGMII PHY configuration in BDK to detect modules on bootup * Linux Kernel run-time hot-plug configuration: - add I2C controller support to mscc phy driver - add DTS configuration (Documentation/devicetree/bindings/net/sff,sfp.txt) References: * [https://en.wikipedia.org/wiki/Small_form-factor_pluggable_transceiver Small form-factor pluggable transceiver]
