The HW link id is a unique identifier for all hardware links participating in the multi link group. Therefore, the current MAC id derivation is insufficient to process the partner rx buffer in the Multi-Link Operation. So derive the MAC id from the HW link id and implementing this change in rx processing will enable the scaling of partner buffer processing in Multi-Link Operation.

However, cfg80211 already provides a suitable data structure struct wiphy_radio_freq_range to store this information efficiently. Additionally, for multi radio per wiphy infrastructure, this frequency range information is essential. In future patches using struct wiphy_radio_freq_range makes the code simpler.

The driver needs to group multiple discrete hardware components, each acting as a link in MLO, under one wiphy. Consequently, the driver advertises multi-hardware device interface combination capabilities specific to the radio, including supported frequencies. The global interface combination represent the combined interface capabilities.
