"This can happen if you filled up your socket buffer, but it is highly
operating system dependent. Since UDP does not provide any guarantee
your operating system can decide to do whatever it wants when your
socket buffer is full: block or drop. You can try to increase SO_SNDBUF
for temporary relief. This can even depend on the fine tuning of your
system, for instance it can also depend on the size of the TX ring in
the driver of your network interface."

so it is mac80211/ath9k here, hmmm...bye, bastian
