Re: [PATCH v3 03/10] NTB: Introduce helper functions to calculate logical port number

This patch introduces the "Logical Port Number" which is similar to the "Port Number" in that it enumerates the ports in the system.

The original (or Physical) "Port Number" can be any number used by the hardware to uniquley identify a port in the system. The "Logical Port

Number" enumerates all ports in the system from 0 to the number of ports minus one.

For example a system with 5 ports might have the following port numbers which would be enumareted thusly:

• • ntb_logical_port_number() - get the logical port number of the local port
• • @ntb: NTB device context.
• • The Logical Port Number is defined to be a unique number for each
• • port starting from zero through to the number of ports minus one.
• • This is in contrast to the Port Number where each port can be assigned
• • any unqique physical number by the hardware.

• • ntb_peer_logical_port_number() - get the logical peer port by given index
• • @ntb: NTB device context.
• • @pidx: Peer port index.
