Subject: [PATCH 0/9] staging: octeon: multi rx group (queue) support

Hi,

This series implements multiple RX group support that should improve
the networking performance on multi-core OCTEONs. Basically we register
IRQ and NAPI for each group, and ask the HW to select the group for
the incoming packets based on hash.

Tested on EdgeRouter Lite with a simple forwarding test using two flows
and 16 RX groups distributed between two cores - the routing throughput
is roughly doubled.

A.

Aaro Koskinen (9):
  staging: octeon: disable rx interrupts in oct_rx_shutdown
  staging: octeon: use passed interrupt number in the handler
  staging: octeon: pass the NAPI instance reference to irq handler
  staging: octeon: move common poll code into a separate function
  staging: octeon: create a struct for rx group specific data
  staging: octeon: move irq into rx group specific data
  staging: octeon: move group number into rx group data
  staging: octeon: support enabling multiple rx groups
  staging: octeon: enable taking multiple rx groups into use
