Usually EAGAIN means the device is busy, but I have never seen it happen
on send.  Attached a small patch, could you test this?  It sets
SO_SNDBUF to the same value as SO_RCVBUF, perhaps the output buffer is full?

If it gives permission denied, change SO_SNDBUF into SO_SNDBUFFORCE

Otherwise, netstat -su?  does it report send buffer overruns (or can it
possibly do so?).

Does a symmetric rcvbuf-sndbuf setting make sense (apart from this
test)?  Or do you need to be able to configure the sndbuf?  (question
only applicable if attachment solves problem :-)  ).

Best regards,
   Wouter
