Removed the line
tvb_ensure_bytes_exist(tvb, offset, 44);
from again.
This is not correct, because the frame might have been captured before the
os added the padding bytes. E.g. in Windows the frames are captured on the
protocol layer. When another protocol driver sends a frame this frame does
not include the padding bytes.
Also the dataLength variable in case of bMox==TRUE was not calculated
correctly.
