Which I think has been proven to have been a mistake. Instead over overriding irq affinity though proc/irq under the covers of the driver and hoping for the best the driver itself should have the opportinuty to set the affinity for its objects directly. Lets us not repeat this mistake with steering tag. The driver should always be involved in this stuff, if you want it to work with DPDK then go through the kernel driver that DPDK is running on top of (VFIO or RDMA) Jason
