Stratix V Hard IP for PCI Express Issue If rx_st_mask Toggles when rx_st_ready Is 0

Description

The Stratix V Hard IP for PCI Express IP Core may send invalid data if rx_st_mask toggles while rx_st_ready is 0. The Hard IP may not recover once this event occurs.

Resolution

There is not a workaround. Altera recommends that you disable the rx_st_mask signal for Stratix V devices.
