 conversion can be done in user space, for example by ethtool.
 
+When set, the optional ``ETHTOOL_A_C33_PSE_PRIO_MODE`` attributes is used to
+control the C33 PSE priority mode. The available mode are:
+
+1. Static Method:
+
+   This method involves distributing power based on PD classification. It’s
+   straightforward and stable, with the PSE core keeping track of the budget
+   and subtracting the power requested by each PD’s class.
+
+   Advantages: Every PD gets its promised power at any time, which guarantees
+   reliability.
+
+   Disadvantages: PD classification steps are large, meaning devices request
+   much more power than they actually need. As a result, the power supply may
+   only operate at, say, 50% capacity, which is inefficient and wastes money.
+
+2. Dynamic Method:
+
+   This method monitors the current consumption per port and subtracts it from
+   the available power budget. When the budget is exceeded, lower-priority
+   ports are shut down. This method is managed by the PSE controller itself.
+
+   Advantages: This method optimizes resource utilization, saving costs.
+
+   Disadvantages: Low-priority devices may experience instability.
+
+When set, the optional ``ETHTOOL_A_C33_PSE_PRIO`` attributes is used to
+control the C33 PSE priority. Allowed priority value are between zero
+and the value of ``ETHTOOL_A_C33_PSE_PRIO_MAX`` attribute.
+
+A lower value indicates a higher priority, meaning that a priority value
+of 0 corresponds to the highest port priority.
+Port priority serves two functions:
+
+ - Power-up Order: After a reset, ports are powered up in order of their
+   priority from highest to lowest. Ports with higher priority
+   (lower values) power up first.
+ - Shutdown Order: When the power budget is exceeded, ports with lower
+   priority (higher values) are turned off first.
+
+When set, the optional ``ETHTOOL_A_C33_PSE_DISCON_POL`` attributes is used
+to control the disconnection policy. When port are on the same priority
+the disconnection policy is used to specify the shutdown order.
