> 65535 bytes with ETHERNET_MAX_PACKET_BYTES I take it as a query on how easy it is for VPP to support super jumbo frames [0].
> most networks use approximately 9000 In theory, VPP could allow higher values to be set on demand, while making sure the default MTU values remain small enough. Even if networking hardware lacks the support, users can see benefits in memif and similar "virtual" devices. The real question is whether VPP will work when recompiled with the higher limit, or whether some pieces of VPP code will blow up (because they assume frame size is never much larger than ~9000 bytes).

VPP has standart burned in value. ________________________________ От: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> от имени Алексей <[email protected]<mailto:[email protected]>> Отправлено: 21 марта 2020 г. 1:44:37 Кому: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> Тема: [vpp-dev] Increase MTU from ethernet packets Hello, VPP support maximum mtu 9216 bytes. Else increase mtu from 65535 bytes with ETHERNET_MAX_PACKET_BYTES environment and recompile VPP?
