PCIe Gen 3 tfc_nph_av hang

Hi all,

I'm designing high throughput PCIe application. To avoid Head Of Line ( as mention in pg 213), I added logic to control nonposted request. (tfc_nph_av[3:0]). When I run with as low bandwidth as 10G, everything is ok. When I get higher, the tfc_nph_av signal hangs with value 1., no more credit updated. Do you have any idea 'bout this?

Thank you so much
