From: Eli Cohen Date: Wed, 15 Jul 2020 04:28:34 +0000 (-0700) Subject: net/mlx5: Add interface changes required for VDPA X-Git-Tag: v5.15~3122^2~19^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8a06a79b0aa811eee6d56b3cfc738c5d08b0dc74;p=platform%2Fkernel%2Flinux-starfive.git net/mlx5: Add interface changes required for VDPA Rename mlx5_ifc_device_virtio_emulation_cap_bits to mlx5_ifc_virtio_emulation_cap_bits to match names produced by the tools producing these auto generated files. In addition missing capabilities that will be required by VDPA implementation.
