We developed the board using imx6 solo and Linkstreet (Ethernet switch) of Marvell.

However, the board has a problem which an ENET_EIR [GRA] interrupt occurs and transmitting stops, when traffic increases.


The occurrence of cause of GRA interrupt is mention to the reference manual( Graceful transmit stop (GTS)),

but that doesn't apply to any of them.


I think that the Marvell tag added to the header caused problem.

Then, please let me know about following,


- When it stops by GRA interrup, is there any method of resume transmission?

The method of clearing ENET_TCR [GTS] was not effective.


-I think that the Marvell tag is misrecognition to be pause frame.

Is there any method of disable pause frame?
