Maybe we should increase the default parameter for the txqueuelen. I
know there is some science about to calculate bandwidth, payload, etc to
calculate a good value.
I know ethernet changed to 1000 because gigabit ethernet is common
nowadays, before it was 100.
Our default value is 300 (don't know why, Alan increased it one day), see
commit e937f583ec3a40cccd480b40d8c6d54751781587.
It was 10 before and 10 is really too small...
