[wireless-next,v5,0/3] wifi: MBSSID support in MLO

Message

Aloka Dixit April 8, 2025, 6:44 p.m. UTC

During non-transmitted (nontx) profile configuration, interface
index of the transmitted (tx) profile is used to retrieve the
wireless device (wdev) associated with it. With MLO, this 'wdev'
may be part of an MLD with more than one link, hence only
interface index is not sufficient anymore to retrieve the correct
tx profile. Add a new attribute to configure link id of tx profile.

Similarly, storing 'vif' of tx profile inside 'vif' for nontx
profiles is not sufficient for MLO, instead store tx link data
inside each nontx link data structure.

v5:
(1) Added a check for tx_link_id when the parameters are passed for
the transmitting interface itself.
(2) Added branch tags in all patches.
(3) Reduced lines to 80 characters wherever possible.

v4:
(1) Pre-requisite driver patches are merged in wireless-next
    hence this series should apply cleanly now.\
(2) Refactored possible driver changes into a separate patch.
(3) Found a change missed in HWSIM causing compilation errors,
    replaced mbssid_tx_bss by tx_bss_conf and confirmed
    successful compilation.
(4) Replaced vif->bss_conf->ema_ap by link_conf->ema_ap.
