+
+ Note that having too large a FSL_FM_MAX_FRAME_SIZE (much larger
+ than the actual MTU) may lead to buffer exhaustion, especially
+ in the case of badly fragmented datagrams on the Rx path.
+ Conversely, having a FSL_FM_MAX_FRAME_SIZE smaller than the

+ to the private data area already reserved for driver internal
+ use. The provided value must be a multiple of 16.
