With the introduction of Multi Link Operation (MLO) support in
IEEE802.11be, each EHT AP/non AP interface is capable of
operating with multiple radio links.
cfg80211/mac80211 expects drivers to abstract the communication
between such Multi Link HW and mac80211/cfg80211 since it depends
on different driver/HW implementation. Hence the single wiphy
abstraction with changes in datastructures were introduced in
"wifi: ath12k: Introduce hw abstraction"
This patchset extends the implementation to allow combination
of multiple underlying radios into a single composite hw/wiphy
for registration. Since now multiple radios are represented by
a single wiphy, changes are required in various mac ops that the
driver supports since the driver now needs to learn on how to tunnel
various mac ops properly to a specific radio.
This patchset covers the basic mac80211 ops for an interface bring up
and operation.
Note:
Monitor and hw reconfig support for Single Wiphy will be done in future
patchsets.
thinking about this series in the context of some other patches I've been
reviewing recently, I don't think this series should be talking about
supporting multiple radios with a single wiphy, but instead about
supporting
multiple devices with a single wiphy. After all, the existing logic
already
supports a single device with multiple radios, so it isn't the
multitude of
radios that is the issue, it is the multitude of devices.
So far we are only combining radios of a device (ab) and registering it
as single HW(ah) to mac80211. Currently ah will only contain radios of
one device. Combining multiple devices into a single HW is different
series (where ag will be introduced).
Having said that, even if multiple devices are combined with ag, at hw
(ah) level there are only radios of multiple devices (ab) and hence
these patches stay generic and call them as radios.
this would have ramifications on many of the commit messages in this
series.
Hi Jeff,
Planning to re-spin v7 to address comments on PATCH 07/12, do you have
anymore comments on the commit text or other patches ?
