====================
sunvnet: NAPIfy sunvnet
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.
