@hamzazafar fyi: you san simply convert any string to a Protocol type and use it in struct. See an example in terraform provider: https://github.com/terraform-providers/terraform-provider-openstack/blob/152286f9ae3d016cb38d53ae2c0d1920d967d368/openstack/lb_v2_shared.go#L74

Probably it does make sense to add all supported protocols, or simply convert the type to a string.
