Oleksij Rempel 2ccb1ac2d0 net: dsa: microchip: dcb: rename IPV to IPM 
IPV is added and used term in 802.1Qci PSFP and merged into 802.1Q (from
802.1Q-2018) for another functions.

Even it does similar operation holding temporal priority value
internally (as it is named), because KSZ datasheet doesn't use the term
of IPV (Internal Priority Value) and avoiding any confusion later when
PSFP is in the Linux world, it is better to rename IPV to IPM (Internal
Priority Mapping).

In addition, LAN937x documentation already use IPV for 802.1Qci PSFP
related functionality.

* 2. 12 mA or 16 mA is often used for MII, RMII, and SPI interface with
* using 1.8V VDDIO.
* 3. 20 mA or 24 mA is often used for GMII/RGMII interface with using 2.5V
* or 3.3V VDDIO.
* 4. 28 mA is often used for GMII/RGMII interface with using 1.8V VDDIO.
* 5. In same interface, the heavy loading should use higher one of the
* drive current strength.
* - for low speed signals
* 1. 3.3V VDDIO, use either 4 mA or 8 mA.
* 2. 2.5V VDDIO, use either 8 mA or 12 mA.
* 3. 1.8V VDDIO, use either 12 mA or 16 mA.
* 4. If it is heavy loading, can use higher drive current strength.

* ksz_update_port_member - Adjust port forwarding rules based on STP state and

* @dev: A pointer to the struct ksz_device representing the device.
* @port: The port number to adjust.
*
* This function dynamically adjusts the port membership configuration for a
* specified port and other device ports, based on Spanning Tree Protocol (STP)
* states and port isolation settings. Each port, including the CPU port, has a
* membership register, represented as a bitfield, where each bit corresponds
* to a port number. A set bit indicates permission to forward frames to that
* port. This function iterates over all ports, updating the membership register
* to reflect current forwarding permissions:
*
* 1. Forwards frames only to ports that are part of the same bridge group and
* in the BR_STATE_FORWARDING state.
* 2. Takes into account the isolation status of ports; ports in the
* BR_STATE_FORWARDING state with BR_ISOLATED configuration will not forward
* frames to each other, even if they are in the same bridge group.
* 3. Ensures that the CPU port is included in the membership based on its
* upstream port configuration, allowing for management and control traffic
* to flow as required.
