    ENGR00235090 FEC: Workaround for FEC RX hang with stress test · b3ce4ba4
    Fugang Duan authored
    When do Ethernet UDP stress overnight test with abundance of
    data transmission, RX path may hang-on.
    Dump the RX BD, found all BD "Empty" bit is cleared, which means
    CPU read BD status is not right and waiting here.
    
    Change BD memroy attribute from Normal to strongly ordered:
    changes the memory attribute of C=0, B=0 instead of C=0, B=1.
    Apply the change, the issue cannot be reproduced.
