Hi, Trying to find out why 82598 is dropping packets (rx_missed_errors) while the cpus are only 30% utilized (using 8-queues), I realized that DCA is disabled; that is (adapter->flags & IXGBE_FLAG_DCA_ENABLED) is false while the kernel has been compiled with IXGBE_DCA and INTEL_IOATDMA marked as builtins.
Inspecting the code showed that dca_add_requester() in ixgbe_probe() fails with -ENODEV and in dca_add_requester(), dca_find_domain() returns NULL. I tried the card on HP DL380G6 and BL460cG6 with the same result. Is there something I'm missing? Also could it be related to packet drops?
