Why do my non-posted TLPs not appear on the receive AVST interface?

Description

As described in the user guides for the Hard IP for PCI Express* Avalon-ST Interface, the rx_st_mask input will stall all non-posted TLPs when asserted.

Resolution

To work around this issue, ensure that the rx_st_mask input is deasserted when you wish to receive non-posted TLPs on the AVST Rx interface.
