Subject: [PATCH mlx5-next 2/4] net/mlx5: Add dynamic MSI-X capabilities bits
From: Leon Romanovsky <leonro@...dia.com>
These new fields declare the number of MSI-X vectors that is
possible to allocate on the VF through PF configuration.
Value must be in range defined by min_dynamic_vf_msix_table_size
and max_dynamic_vf_msix_table_size.
The driver should continue to query its MSI-X table through PCI
configuration header.
