Subject: [PATCH mlx5-next v6 2/4] net/mlx5: Add dynamic MSI-X capabilities bits
Date: Tue,  9 Feb 2021 15:34:43 +0200	[thread overview]
Message-ID: <20210209133445.700225-3-leon@kernel.org> (raw)
In-Reply-To: <20210209133445.700225-1-leon@kernel.org>

From: Leon Romanovsky <leonro@nvidia.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.
