From: Leon Romanovsky Date: Sun, 14 Mar 2021 12:42:54 +0000 (+0200) Subject: net/mlx5: Add dynamic MSI-X capabilities bits X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0b989c1e37053196676b2238f82195bd5a339d58;p=linux.git net/mlx5: Add dynamic MSI-X capabilities bits 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.
