    bnxt_en: Fix firmware message delay loop regression. · cc559c1a
    Michael Chan authored
    A recent change to reduce delay granularity waiting for firmware
    reponse has caused a regression.  With a tighter delay loop,
    the driver may see the beginning part of the response faster.
    The original 5 usec delay to wait for the rest of the message
    is not long enough and some messages are detected as invalid.
    
    Increase the maximum wait time from 5 usec to 20 usec.  Also, fix
    the debug message that shows the total delay time for the response
    when the message times out.  With the new logic, the delay time
    is not fixed per iteration of the loop, so we define a macro to
    show the total delay time.
