Max Frame Size value is shown as 34816 in fdmishow from Switch.

The driver uses bbRcvSize in common service param which is obtained
from the READ_SPARM mailbox command. The bbRcvSize field which is
displayed is a three nibble field but the driver is printing a full
four nibbles.

Fix by masking off the upper nibble.
