Hello,

I'm working with C6748, NDK 2.20.05.33, BIOS 5.41.11.38.

If the network scheduler is in interrupt mode, is the PRD function being executed? If yes, for which reason?

Anatoly,

Yes. The PRD is driving the stack for things like polling the driver to see if it has any actions to perform (that are not interrupt driven). It also drives timeouts in the protocols (e.g. TCP).
