This is true of ANY manufacturer's 16-bit PCMCIA card (Xircom, 3Com, Intel, etc.)  Since there is no such thing as a "15mbps hub", or a "20mbps hub", it wouldn't make sense to call it a 20mbps PC Card.  These kind of cards do connect to 100mbps networks, although they don't fully realize the entire bandwidth.
