2021-11-27devices: fix af_packet GSO checkNathan Skrzypczak1-1/+6
Type: fix This fixes the GSO size calculation in af_packet which didn't include the ethernet size. This is not ideal, as we default to the host side mtu to check whether a packet is GSO or not and to set the GSO size. But there doesn't seem to be more info passed with the packets.

Type: fix https://gerrit.fd.io/r/c/vpp/+/34027 added support for l3 mode, but as the eth_mode constant was set to 1 we did default to l3 mode in the api. This reverts to the original logic.

2021-09-07devices: restore regular af-packet tx pathMohammed Hawari2-21/+28
This change restores the af_packet tx path prior in use prior to Change Idf0bdd88990254a614962c2f7bc3e0292ccfd61a but fixes the stalling issue by ensuring that the next tx frame pointer is only incremented when a new tx frame is used. This change also enables the af_packet PACKET_QDISC_BYPASS option, for better performance.

2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne1-1/+0
trajectory trace has been broken for a while because we used to save the buffer trajectory in a vector pointed to in opaque2. This does not work well when opaque2 is copied (eg. because of a clone) as 2 buffers end up sharing the same vector. This dedicates a full cacheline in the buffer metadata instead when trajectory is compiled in. No dynamic allocation, no sharing, no tears.

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-4/+9
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.

2021-02-05devices: af-packet gso mtuNathan Skrzypczak4-38/+126
Type: fix Set the GSO flag when buffer length exceeds the linux mtu. Don't listen for mtu changes on linux side for now. This also fixes a TX issue, as we only search for valid frames on tx to the extent of n_left, we might stay stuck.

2020-05-27ethernet: fix DMAC check and skip unnecessary ones (VPP-1868)John Lo1-1/+1
Fix and optimize DMAC check in ethernet-input node to utilize NIC or driver which support L3 DMAC-filtering mode so that DMAC check can be bypassed safely for interfaces/sub-interfaces in L3 mode. Checking of interface in L3-DMAC-filtering state to avoid DMAC check require the following: a) Fix interface driver init sequence for devices which supports L3 DMAC-filtering to indicate its capability and initialize interface to L3 DMAC-filtering state. b) Fix ethernet_set_flags() function and its associated callback flags_change() functions registered by various drivers in interface infra to provide proper L3 DMAC filtering status. Maintain interface/sub-interface L3 config count so DMAC checks can be bypassed if L3 forwarding is not setup on any main/sub-interfaces.
