Subject: [PATCH net-next V1 8/9] net/mlx5: Use flow steering infrastructure for mlx5_en
From: Maor Gottlieb <maorg@...lanox.com>
Expose the new flow steering API and remove the old
one.
Few changes are required:
1. The Ethernet flow steering follows the existing implementation, but uses
the new steering API. The old flow steering implementation is removed.
2. Move the E-switch FDB management to use the new API.
3. When driver is loaded call to mlx5_init_fs which initialize
the flow steering tree structure, open namespaces for NIC receive
and for E-switch FDB.
4. Call to mlx5_cleanup_fs when the driver is unloaded.
