Konstantin,
Is there a possibility to read information about available space in NIC queue for TX.
It is quite easy to compute (or even available directly) and very useful especially for application sending multi-descriptor packets like TCP TSO.
Now there is no access to such information and the transmit packet function must be called to
be sure that there is available space.
