From 6e862ec7b63e177b9b0103612848b3377271729b Mon Sep 17 00:00:00 2001 From: Vratko Polak Date: Mon, 22 May 2023 10:14:09 +0200 Subject: feat(interface): apply MTU for dpdk plugin ifaces When changing MTU on a running VPP, the interface has to be down. - Other plugins (rdma, avf, af_xdp) need vastly different logic, so support for them will be added later. + Mlx5-core does not need to set MTU on Linux interface. + MTU setting now does not happen at final setting path up, it happens in driver initialization layer instead E.g. AVF tests will not attempt to change MTU. + MTU edit removed from some non-hardware interfaces (including memif) e.g. bond interfaces. MTU on parent hw interface seems to be enough. + The non-jumbo MTU value used is 1800, so 1518B tests with additional encapsulation can still work. + When VPP MTU setting fails, the failure is now propagated. Previously, the failure was just logged and ignored, but now there is no reason to hide it.
