2.5.6. Incorrect TLP length decoding for 4 KB memory read request

Description

In the Agilex™ 5 PCIe Hard IP, memory read request of 4 KB cannot be transmitted correctly due to the TLP length decoding error. Sending a 4 KB memory read request can cause a malformed TLP and fatal error in the system.

Workaround

Limit the Maximum Read Request Size to 2 KB option instead of 4 KB to avoid potential fatal error.
