The congestion control happens at two levels. You are right that the
socket buffer acts as one limit. However, other applications may also
rely on the TX queue being full as the throttle (by setting a
sufficiently large socket buffer size).
Do you happen to have an example of an application that does this that
could be used for testing? :)

ip: Report qdisc packet drops
You should be able to do a UDP flood while setting IP_RECVERR to
detect the packet drop due to a full queue which AFAICS will never
happen with the current mac80211 setup.
Yup, got that part. Was just wondering if you know of any applications
that already do this, that I could test without having to write my
own... :)
Hi Bob,
Is this something that could be easily implemented in iperf?
