RDMA/mlx5: Add missed RST2INIT and INIT2INIT steps during ECE handshake
Missed steps during ECE handshake left userspace application with less options for the ECE handshake. Pass ECE options in the additional transitions. Fixes: 50aec2c3135e ("RDMA/mlx5: Return ECE data after modify QP") Link: https://lore.kernel.org/r/20200616104536.2426384-1-leon@kernel.org Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
