MEMBERS

kref

reference count for this port.

rad[8]

Relative Address to talk to this branch device.

lct

Link count total to talk to this branch device.

num_ports

number of ports on the branch.

msg_slots

one bit per transmitted msg slot.

ports

linked list of ports on this branch.

port_parent

pointer to the port parent, NULL if toplevel.

mgr

topology manager for this branch device.

tx_slots[2]

transmission slots for this device.

last_seqno

last sequence number used to talk to this.

link_address_sent

if a link address message has been sent to this device yet.

guid[16]

guid for DP 1.2 branch device. port under this branch can be identified by port #.

DESCRIPTION

This structure represents an MST branch device, there is one primary branch device at the root, along with any other branches connected to downstream port of parent branches.
