  MAC address bits in mask registers should be set to zero
when the is mac mask is 0xFF, otherwise if it is 0x0
these bits should be to 0x3F.

Fixes: 82fb702077f6 ("ixgbe: support new flow director modes for X550")

Signed-off-by: Wei Zhao <wei.zhao1@intel.com>

v2:
-change mask bits set method to support more mac mask.

v3:
-change mask and with 0x3F to macro definition.
