I have tested this patch and the result seems positive. Please let me know if any more/different testing would help. My test was to examine /proc/interrupts after booting a Salvator-X board using NFS root. The test used net-next merged with v4.5-rc1 (for r8a7795/Salvator-X support). I then applied this patch. Without this patch: # grep eth /proc/interrupts 74: 13002 0 0 0 GIC-0 93 Level eth0 76: 3 0 0 0 GIC-0 95 Level eth0 With this patch: # grep eth /proc/interrupts 52: 8744 0 0 0 GIC-0 71 Level eth0:ch0:rx_be 53: 0 0 0 0 GIC-0 72 Level eth0:ch1:rx_nc 70: 4277 0 0 0 GIC-0 89 Level eth0:ch18:tx_be 71: 0 0 0 0 GIC-0 90 Level eth0:ch19:tx_nc 74: 0 0 0 0 GIC-0 93 Level eth0:ch22:multi 76: 3 0 0 0 GIC-0 95 Level eth0:ch24:emac Please feel free to add: Tested-by: Simon Horman <horms+rene...@verge.net.au>
