Alexander Sverdlin 0c34bb598c net: octeon: mgmt: Repair filling of RX ring ... The removal of mips_swiotlb_ops exposed a problem in octeon_mgmt Ethernet driver. mips_swiotlb_ops had an mb() after most of the operations and the removal of the ops had broken the receive functionality of the driver. My code inspection has shown no other places except octeon_mgmt_rx_fill_ring() where an explicit barrier would be obviously missing. The latter function however has to make sure that "ringing the bell" doesn't happen before RX ring entry is really written. The patch has been successfully tested on Octeon II.
