The mvneta Ethernet driver is used on a few different Marvell SoCs.
Some SoCs have per cpu interrupts for Ethernet events, the driver uses
a per CPU napi structure for this case. Some SoCs such as armada 3700
have a single interrupt for Ethernet events, the driver uses a global
napi structure for this case.
Current mvneta_config_rss() always operates the per cpu napi structure.
Fix it by operating a global napi for "single interrupt" case, and per
cpu napi structure for remaining cases.

Looks reasonable.
