The Virtual Channel Link Control changes the link control channel. There are
two options: 0 and 1.

Option 0 forces data receipt acknowledgments on Class 2 channels to be sent
back on the data channel. This traffic consumes a portion of the available data
channel bandwidth.

Option 1 allows data receipt acknowledgment packets to use the VC-1
(internal Switch traffic channel) which frees additional bandwidth in the data
channel, and transfers the data receipt traffic load to the Switch’s internal
traffic channel.
