Go to System Preferences...Network.
Select the 10GbE port and click "Advanced..."
Select the Hardware tab.
If Jumbo packets are on, turn them off, click OK and click Apply.
If that fixes the problem, then stay at Standard (1500), or check the Jumbo packet setting of every switch and device in the path.

If that doesn't fix the problem, check Flow Control.
If Flow Control is off, turn it on; or if it is on, turn it off. Not all devices support flow control, or the absence of flow control.
