I have a question about 10G SFP+ operation of lsdk 2004.
After 10G bring-up, i can see interface of 10G SFP+.
And tx count is up. but when i tried ping-test, there was no response. so 10G RX operation is not working.
so i check interface with ethtool. i found out that Transceiver is internal mode.
i think Transceiver would be external when fixed-link used.
may i have the reason about rx operation fail ?
i attach some information about status.
* ethtool info.
