> This patchset converts the sunvnet driver to use the NAPI framework.
> Changes since v4 to Patch1: 
>   vnet_event accumulates LDC_EVENT_* bits into rx_event. 
>   vnet_event_napi() unrolls send_events() logic to process all rx_event bits.
> Changes since v5: 
>   Patch 1: use net_device.h definition for NAPI_POLL_WEIGHT.
>   Drop sparclinux changes (patch3) per David Miller feedback 
> 
> Patch 1 in the series addresses the packet-receive path- all
> the vnet_event() processing is moved into NAPI context.
> This patch is dependant on the sparc-next commit:
>   "sparc64: Add vio_set_intr() to enable/disable Rx interrupts"
>   (sparc commit id ca605b7dd740c8909408d67911d8ddd272c2b320)
> 
> Patch 2 uses RCU to fix race conditions between vnet_port_remove and
> paths that access/modify port-related state, such as vnet_start_xmit.
> 
> Patch 3 leverages from the NAPIfied Rx path, 
> dropping superfluous usage of the irqsave/irqrestores on the vio.lock
> where possible.

Series applied, thanks.
