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(23.4.9.4.1 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?
