It seems strange that interrupts would be somehow linked to a
ucontext? interrupts are highly limited, you can DOS the entire system
if someone abuses this.

Generally I expect a properly functioning driver to use one interrupt
per CPU core.

You should tie the CQ to a shared EQ belong to the core that the CQ
wants to have affinity to.
