/**
* The STA is affiliated with an MLD. From Sec. 35.3.7.1.4 of 802.11be D3.0:
* When a link becomes enabled for a non-AP STA that is affiliated with a non-AP MLD
* after successful association with an AP MLD with (Re)Association Request/Response
* frames transmitted on another link [...], the power management mode of the non-AP
* STA, immediately after the acknowledgement of the (Re)Association Response frame
* [...], is power save mode, and its power state is doze.
*
* Thus, STAs operating on all the links but the link used to establish association
* transition to power save mode.
