The Logical Channel Address Range determines the range of addresses
relative to the Logical Channel Base Address that corresponds to the logical
channels of the serial link. The default maps 32 logical channels to a serial
link, but 8, 16 or 24 channels may be mapped to each link to provide a more
compact address space and hence allowing support of more channels.

The address space is contiguous starting at the associated Logical Channel
Base Address. The offset from the base address corresponds to the logical
channel index (PHYID[4:0] value encoded in the serialized cell).
LCBA[11]:
This is the most significant bit of the Logical Channel Base Address for the
link.
