interface: support configuring RSS steering queues
This patch adds the RSS steering queues set interface, and it's implementation in DPDK device: /* Interface to set rss queues of the interface */ typedef clib_error_t *(vnet_interface_rss_queues_set_t) (struct vnet_main_t * vnm, struct vnet_hw_interface_t * hi, clib_bitmap_t *bitmap); This patch also introduces a command line to set the RSS queues: set interface rss queues <interface> <list <queue-list>> To display the rss queues, use "show hardware-interfaces" Below is the example to configure rss queues for interface Gig0: vpp# set interface rss queues Gig0 list 0,2,4-7 vpp# show hardware-interfaces brief Name Idx Link Hardware VirtualFunctionEthernet18/1/0 1 down VirtualFunctionEthernet18/1/0 Link speed: unknown RSS queues: 0 2 4 5 6 7 local0 0 down local0 Link speed: unknown vpp# Users can also configure the rss queues on a dpdk interface in startup.conf: dpdk { dev 0000:18:01.0 { rss-queues 0,2,5-7 } } Type: feature Signed-off-by: Chenmin Sun <chenmin.sun@intel.com> Change-Id: I1835595a1c54016a84eabee9fd62ce137935385d
