If no mcast_rate is set for the wifi-iface then there is no rate_idx (0)
set for the bss. This can break for example 5GHz meshpoint interfaces
because 0 maps to a CCK rate (11Mbit/s).
It must also be avoided that the ath10k-ct internal state for the rates is
not synced with the mac80211 rates state. Otherwise, the user specified
rate (e.g. a wifi-iface mcast_rate for a meshpoint interface) will only be
set on startup. And a short while after that, ath10k-ct specific code in
ath10k_check_apply_special_rates is missing a valid rate in its own
structures and is then recalculating a new default rate. This default rate
is in most situations not the requested rate.

Subject: ath10k-ct: apply mac80211 rates to ath10k-ct rate state
|
|
|
|
The rates from mac80211 have to be copied to the state of ath10k-ct or
|
|
otherwise the ath10k_check_apply_special_rates function overwrites
|
|
them again with some default values. This breaks for example the
|
|
mcast_rate set for a wifi-iface.
