18.4 Incorrect reading of Type 2 Screener registers on GMAC0 and GMAC1
On GMAC0 and GMAC1, Type 2 Screener register reading may be corrupted. This may impact QoS applications based on source/destination IP, source/destination TCP/UDP, Ethertype or VLAN.
Affected registers are GMAC0_ST2RPQx, GMAC0_ST2ERx, GMAC0_ST2CWxRy, GMAC1_ST2RPQx, GMAC1_ST2ERx, GMAC1_ST2CWxRy.
Work Around
Use a shadow copy of the registers and fake the read operation using the shadow
copy.
Warning: With
the debugger, a value read in a register may be corrupted.
