From: Moshe Shemesh <[email protected]>
On dcbnl callback getpgtccfgtx, the driver should check the ets
capability before ets query command is sent to firmware.
It is valid to return from this void function without changing in/out
parameters, as these parameters are initialized to
DCB_ATTR_VALUE_UNDEFINED.
Fixes: 3a6a931dfb8e ("net/mlx5e: Support DCBX CEE API")
