2024-12-12pg: misc improvements and fixesBenoît Ganne1-3/+27
1) pg can typically injects packets in ethernet-input, ip4-input or ip6-input. Make sure offload offsets are correctly set for ip4-input and ip6-input. 2) add hw-addr support for ethernet mode (only available through cli) 3) refactor pg creation code to improve the readability by using data structure pg_interface_args_t 4) fix the pg input and output traces to use headers according to pg interface mode 5) introduce pg interface flags i.e. checksum, gso, gro Type: improvement Change-Id: Iffed502e9c6357d7ef8e8a72217867e8297236aa Signed-off-by: Benoît Ganne <bganne@cisco.com> Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>

2024-07-18pg: fix pcap packet type when writing pcap fileDave Wallace1-0/+9

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-1/+4
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

2020-04-15pg: set vnet buffer flags in pg streamsDave Barach1-0/+3
See .../extras/pg/checksum_offload.pg for a nontrivial example, which deliberately sets bogus ip and udp checksums in the generated packets, then fixes the mess with (software emulated) hardware checksum offload. Validated via "pcap dispatch trace on max 1000 buffer-trace pg-input 100". Packets stuffed into loop1-output have the configured bogus ip and udp checksums. vnet_calc_checksums_inline(...) fixes the checksums, which are correct when packets visit loop1-tx. The packet generator is a dumb robot in this regard. If you ask for a ridiculous flag combination - example: ip4 and ip6 - your mileage may vary.

2019-10-03misc: add "maxframe" and "rate" to packet-generator cli.Christian E. Hopps1-0/+3
Allow for setting the maximum number of generated packets to be included in the frame passed to next nodes. This is very important for testing code which may be susceptible to multi-frame vs single-frame bugs (e.g., code that is doing re-ordering where packets may be buffered between frames). Update: - remove redundant packet "rate" option. - reduce n_max_frame to u32 as that's what pulled from the CLI. Type: feature Signed-off-by: Christian E.
