What about the case AP + STA concurrency? are we going to overwrite
the PSD power and channel flags?
Hi Venkateswara,
This patch is not relation with AP + STA concurrency.
For example, it also has other power intersection in
handle_channel_adjacent_rules().
chan->max_reg_power =
min_t(int, MBM_TO_DBM(power_rule1->max_eirp),
MBM_TO_DBM(power_rule2->max_eirp));
For AP + STA concurrency, it should to maintain 2 group of reg rules,
one is for AP, another is for STA.
Can we maintain two power rules in the same channel one for AP and one
for STA. In this way, we can update the power rules in the same channel
for both AP and STA from the reg rules.
Otherwise, we need to maintain multiple channel lists in sband for all
supported power mode combinations to apply the respective power rules
and build channel flags from the multiple reg rules.
right?
This patch is to handle PSD info in the same reg rules.
It is to process only one reg rule in the reg rules.
AP + STA concurrency is a higher level things than this patch.
