Dear guys.
About this issue.
before the Kernel v5.1.6, We can call the NL80211_CMD_CH_SWITCH_NOTIFY to update
the "bss->freq".
but after the Kernel v5.1.6, station does not use the
NL80211_CMD_CH_SWITCH_NOTIFY before connect.
only can use the NL80211_CMD_CH_SWITCH_STATRED_NOTIFY.
but it does not update the "bss->freq".
Now, I can't send the auth again.
Does someone have any solution ?
Thank a lots
Ouden Lin
