Hi,
I have gotten a new warning while using driver rtl8192se with the mainline
kernel. The splat is as follows:
[42982.577623] ------------[ cut here ]------------

The warning comes from the following fragment in net/mac80211/agg-tx.c:
if (WARN_ON(!tid_tx)) {
ht_dbg(sdata, "addBA was not requested!\n");
goto unlock;
}
Is there something that should be fixed in rtl8192se?
Thanks,
Larry
