The driver's adaptive moderation and DIM are mutually-exclusive options,
and DIM is used by default. Since it is hard to verify all cases that
DIM can get a better result, so keep the adaptive moderation as an
option now, which can be swicthed by the ethtool priv-flag. If DIM is ok
for a long time, then we will send a separate patch to  remove the
adaptive moderation from the driver.

Thanks.
