Why does the Intel® Arria 10® PCI Express* Hard IP lane error status register fail to clear?

Description

Due to a problem with the write address decoding for the Intel® Arria® 10 PCI Express* Hard IP, you may fail to clear the lane error status register after writing ‘1’ to this register.

Workaround/Fix

To work around this problem, write a ‘1’ to link control 3 register (Offset 04h) located in the Secondary PCI Express* Extended Capability. This register will be set and the lane error status register will be cleared.
