When enabling DCB the rings belonging to a q_vector on CPU 0 were not reinitializing their DCA registers. Upon closer inspection the issue was that the q_vector CPU variable was left at 0 resulting in the driver not updating the DCA registers. In order to guarantee the DCA registers will be updated I am adding a couple line change so that we initialize the CPU variable to -1 which will force a DCA update the first time an interrupt fires on that q_vector. In addition we were setting the CPU affinity hint to all CPUs when we were not specifying a CPU. Instead we should leave it as all zeros to avoid any possible confusion about the fact that we shouldn't be giving a hint.
