[PATCH 0/3] wifi: ath12k: Refactor monitor Rx handler

[Karthikeyan Periyasamy]

Currently, monitor support is not added. However, in the future, the
monitor will be enabled. Therefore, refactor the monitor handler, which
help to add monitor support in the future.

[PATCH 1/3] wifi: ath12k: Refactor the monitor Rx parser handler argument

[Karthikeyan Periyasamy]

Currently, the monitor Rx parser handlers
ath12k_dp_mon_rx_parse_status_tlv() and ath12k_dp_mon_parse_rx_dest()
take the device handle from the caller. However, these handlers
functionality is technically pdev specific. Additionally, the device handle
can be retrieved from the pdev handle. Therefore, for better code
understanding, change the monitor Rx parser handlers argument from the
device handle to the pdev handle.

[PATCH 2/3] wifi: ath12k: Refactor the monitor Tx/RX handler procedure arguments

[Karthikeyan Periyasamy]

Currently, the pdev handle is given along with the mac id to all the
monitor Tx/Rx handler procedure arguments. The mac id information is
derived from the pdev handle itself. Therefore, remove the unnecessary
mac id argument from the handler.

[PATCH 3/3] wifi: ath12k: Refactor Rx status TLV parsing procedure argument

[Karthikeyan Periyasamy]

Currently, ath12k_dp_mon_rx_parse_status_tlv() takes the TLV tag, TLV data
and TLV userid as separate arguments from the caller. These argument can
be fetched from the TLV header itself. Therefore, pass the TLV header and
retrieve the necessary fields from the header instead of passing them from
the caller.

BTW I find it confusing that in the commit message you talk about "pdev
handle" but in the code it's named "ar". It would be nice to have
terminology all over. No need to change anything for this patch, just a
small comment for the future.

The commit message doesn't reply to "why?". Is there a clear benefit in
the future or are you just doing random code cleanup?

It benefit in the future for supporting EHT monitor functionality.

How does it help exactly? Having even just one sentence explaining the
motivation in the commit message would help a lot. Otherwise these just
look random changes.

Currently, ath12k_dp_mon_rx_parse_status_tlv() takes the TLV tag, TLV 
data and TLV user ID as separate arguments from the caller. In the 
future, the TLV length will be needed for the EHT monitor TLV tags. 
These arguments can be fetched from the TLV header itself. Therefore, 
instead of increasing the arguments, pass the TLV header and retrieve 
the necessary fields from the TLV header instead of passing them from 
the caller.

Above commit is ok ?
