Re: [dpdk-dev] [PATCH 2/2] net/mlx5: avoid unbind step to enable switchdev mode

Hi, Jan 1. Let's suppose we have the one port NIC, PCI BDF 08:00.0, SR-IOV enabled, 0 VFs is configured, netdev name is ens1f0 (depends on distro and kernel version). 2. Then, we configure 3 VFs with SR-IOV, we get : - 08:00.0 - PF, ens1f0 - 08:00.1 - VF0, ens1f1 - 08:00.2 - VF1, ens1f2 - 08:00

[dpdk-dev] [PATCH 2/2] net/mlx5: avoid unbind step to enable switchdev mode

From: Jan Viktorin The step 4 is a contradiction. It advices to unbind the device from the mlx5_core which removes the associated system network interface (e.g. eth0). In the step 5, the same system network interface (e.g. eth0) is required to exist. Signed-off-by: Jan Viktorin --- doc/guides/

Re: [dpdk-dev] [PATCH 2/2] net/mlx5: avoid unbind step to enable switchdev mode

Hi, Jan Yes, bullet [4] explicitly requires to unbind VFs, and detach the netdevs from the mlx5_core driver. Otherwise, kernel driver refuses to be configured with switchdev mode in [5]. So, [4] can't be skipped. After setting swithdev mode, VFs can be bound back (if it is needed, and these one
