Seems though that the qdisc drop count does not flow into the tx_dropped counter for the interface.And it should not. The qdisc drops the packet due to flow control, not the hardware device. Device drops are for things like transmission errors on the wire. If you start incrementing tx_dropped here, people won't be able to tell they have a deteriorating cable or bad switch or similar.
?? The patch does not do that. That was extra stuff not covered by the patch.
