Re: I want to control network card buffer
You can use pf to configure an ALTQ for default traffic with a bandwidth slightly less than the actual link. This means
that the packets will build up in the ALTQ buffer rather than in the network card Tx descriptors. You can then send your
traffic via a separate higher priority ALTQ.
Note that 250us is a very tight requirement, the default tick in QNX is 1ms.
