Before extracting the tid out of the packet, check if it was qos-data.
Only accept tid values 0-7
Also, avoid accepting the hardware queue as skb queue mapping, it could
lead to an overrun. Instead, derive the hardware queue from the tid number,
in order to avoid issues with packets being filtered multiple times.
This also fixes a mismatch between hardware and software queue indexes.

This is preparation for supporting multiple wiphys per device to support the
concurrent dual-band feature of MT7615D
On the first wiphy, hw->priv will point to struct mt76_dev, which contains a
struct mt76_phy at the start. For the secondary wiphy, hw->priv will point
to a mt76_phy encapsulated in a driver specific struct
To simplify access to struct mt76_phy members from drivers, the driver specific
device struct is changed to add a union of struct mt76_dev and struct mt76_phy
as the first element

This is caused by failing check-cc-enum build check due to the following
compile error:
./include/linux/dynamic_debug.h:77:14: error: 'KBUILD_MODNAME' undeclared (first use in this function); did you mean 'KERN_NODENAME'?
.modname = KBUILD_MODNAME, \
So this patch adds missing KBUILD_MODNAME variable to
CHECK_CC_ENUM_FLAGS in order to make check-cc-enum build check compile
again.
