I agree that having too fine grained setup for the buffers is bad and
should be avoided. The current setup of RX, TX and shared DATA buffers
has worked for UDP quite well.
We do however still need to figure out, for udp, how to prevent:
- rx path starving tx path to dead lock
- multiple tx paths deadlocking (by attempting to acquire buffers incrementally)
