I'm trying to add ability to ath10k to set an arbitrary tx-rate mask.

I know firmware will need to be modified...that is not the issue currently.
My problem is that I seem not be mis-understanding how the code to set
rates work.
Ahhh, I think I see. For HW rate-ctrl, the driver is going to need to keep
the config values from the 'set_bitrate_mask' logic in the driver
and deal with it accordingly....
Thanks,

I have this code:
static void ath10k_peer_assoc_h_rate_overrides(struct ath10k *ar,
struct ieee80211_vif *vif,
struct ieee80211_sta *sta,
struct wmi_peer_assoc_complete_arg *arg)
{
struct ath10k_vif *arvif = ath10k_vif_to_arvif(vif);
const struct ieee80211_supported_band *sband;
const struct ieee80211_rate *rates;
u32 ratemask;
int i, j;
int band = ar->hw->conf.chandef.chan->band;
if (! test_bit(ATH10K_FW_FEATURE_WMI_10X_CT, ar->fw_features))
return;
lockdep_assert_held(&ar->conf_mutex);
sband = ar->hw->wiphy->bands[band];
ratemask = sta->supp_rates[band];
rates = sband->bitrates;
ath10k_warn(ar, "band: %d ratemask: 0x%x\n", band, ratemask);
It is called when I run the command below:
iw wlan0 set bitrates legacy-5 6 12
But, rate-mask has all bits set...I would expect only bits corresponding
to rate 6 and 12 to be set.
[ 7487.627841] ath10k_pci 0000:05:00.0: band: 1 ratemask: 0xff
I'll go dig through the stack next..but if anyone has pointers, they would be welcome.
Thanks,
Ben
