PHY interrupt


I use fast IP for quick ethernet packet transfer on my DIGI EM, but I find it is still very slow. I found the BSP_USE_PHY_INTERRUPT and I think it could solve my problem. However the NETOS 6.0 documentation specifies that it is not compatible with NS7520. On the other hand, the NETOS 6.3 documentation don’t tell it anymore: is the NS7520 used on DIGI EM now compatible with PHY interrupt?
I don’t want to crash my DIGI…

Thanks for any information,
