Increase interframe delay for FEC tx

Hi, We've got a product running 3.0.35 kernel on iMX6 Solo. This product transmits quite a lot of UDP data in bursts to a multicast address. We also got a switch used with this product (which we can't replace). The problem is that the switch starts dropping frames when we put this product and its previous version on the same switch. It seems that the switch can't handle these bursts of UDP traffic. If I use different switch it helps. When I put little delay in fec driver, the problem goes away. But putting delays in the driver doesn't seem like a good idea. I tried to find if it's possible to somehow maybe configure this but failed. So what do you think would be the proper solution?

Thanks

Is it a Gigabit switch? If so then you could try forcing the link speed down to 100mbps, either at the iMX6 interface or at the switch end if it is a managed switch with configuration interface.

No, unfortunately it's not - it's based on Micrel KSZ8995XA chip 10/100.
