2021-03-19interface: add capabilities flagsMohsin Kazmi1-4/+9
Type: improvement This patch adds flags to represent the modern NICs capabilities. Change-Id: I96d38d9ab7eac55974d72795cd100d8337168e1e Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>
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.

In current implementation, with function af_packet_set_interface_next_node invoked next hop graph node index can be set to apif->per_interface_next_index, but it's not set to next0 properly for packet processing in af_packet_device_input_fn.

2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace2-1/+3
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included. This results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.

Enabled only if the macro is detected - apparently not present on archaic distributions.
