    3636== SFP (Small form-factor pluggable transceiver) support
    37 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.
     37The 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:
     38 * The BDK can be augmented to detect an SFP module and configure the OcteonTX BGX network device accordingly. This would not allow any hot-plug or hot-swap SFP support. Gateworks has a patch available with limited support for this.
     39 * Support could be added to the Linux kernel to expose the Microsemi VSC8574 I2C controller channels and register them with the kernel allowing the native kernel SFP support that has been added since the 4.14 kernel. This could allow more standardized SFP detection and hotplug support. Gateworks has not pursued this path.
