In MCMP mode, a digital-sharing group may also be formed by assigning the same channel to each port
wanted in the group. The host protocol must enforce the order of transmissions to avoid collisions.
If contention is desired and the digital-sharing group consists of adjacent ports, the digital-sharing group
can be recreated via configuration options Share Dev, Lowest Port#, and # of Ports in Gp. The
digital-sharing group can then be configured for contention via Port Cntrl.
