Hi Skyler,

Response from Intel team:

In the ethtool -m output pasted I see TX and RX optical power is fine.
Could you request fault status on both sides? Just want to check if link
is down because we are at local-fault or link partner is at local-fault.

rmmod ixgbe
modprobe ixgbe
ethtool -S eth0 | grep fault

Since it is 10G, if our side TX is ON (power level says it is) then we
should expect link partner RX to be locked so cannot be at Local Fault.

Skyler, please gather that ethtool -S data for us.
