+This variable controls how to pad short frames for DP83815/DP83816
+controllers on the specified device.
+DP83815/DP83816 controllers are known to pad 0xFF for short frames
+which is violation of RFC 1042.
+Set this variable to a non-zero value to let driver manually pad
+each short frame with zeros at the cost of extra CPU cycles.
+The default value is 0 to let hardware perform automatic padding.
