Merge branch 'vhca-tunnel' into rdma.git for-next
Max Gurtovoy says:
====================
Those two patches introduce VHCA tunnel mechanism to DEVX interface
needed for Bluefield SOC. See extensive commit messages for more
information.
====================
Based on the mlx5-next branch from
git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux for
dependencies
* branch 'vcha-tunnel':
IB/mlx5: Implement VHCA tunnel mechanism in DEVX
net/mlx5: Introduce VHCA tunnel device capability
