18.3 Incorrect reading of Type 1 Screener registers on GMAC0 and GMAC1
On GMAC0 and GMAC1, Type 1 Screener register reading may be corrupted. This may impact QoS-based applications using DS/TC fields or TCP/UDP ports.
Affected registers are GMAC0_ST1RPQx and GMAC1_ST1RPQx.
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.
