2019-10-03	vlib: add flag to explicitelly mark nodes which can init per-node packet trace	Damjan Marion	1	-0/+1
	Type: feature Change-Id: I913f08383ee1c24d610c3d2aac07cef402570e2c Signed-off-by: Damjan Marion <damarion@cisco.com> (cherry picked from commit 7ca5aaac10e95306f74ea4afd52110dd46aa0381)
2019-07-23	api: binary api cleanup	Dave Barach	1	-1/+1
	Multiple API message handlers call vnet_get_sup_hw_interface(...) without checking the inbound sw_if_index. This can cause a pool_elt_at_index ASSERT in a debug image, and major disorder in a production image. Given that a number of places are coded as follows, add an "api_visible_or_null" variant of vnet_get_sup_hw_interface, which returns NULL given an invalid sw_if_index, or a hidden sw interface: - hw = vnet_get_sup_hw_interface (vnm, sw_if_index); + hw = vnet_get_sup_hw_interface_api_visible_or_null (vnm, sw_if_index); if (hw == NULL || memif_device_class.index != hw->dev_class_index) return clib_error_return (0, "not a memif interface"); Rename two existing xxx_safe functions -> xxx_or_null to make it obvious what they return.

2018-11-13	vlib rename vlib_frame_args(...) to vlib_frame_scalar_args(..)	Damjan Marion	1	-3/+3
	Typically we have scalar_size == 0, so it doesn't matter but vlib_frame_args was providing pointer to scalar frame data, not vector data.

2018-07-26	pp2: change default queue size	Brian Brooks	1	-2/+2
	Reduce default queue size to twice the vlib frame size. This throttles the PP from transferring more packets than are necessary for the next round of graph execution on a core. When combined with DMA'ing into L3 cache, Mpps for 64B packets increases 35%. Change-Id: I0afe426d23560f262fdc56accb6302b099bd0076 Signed-off-by: Brian Brooks <brian.brooks@arm.com>
