NAME
       libnvmf_kernel_option_supported - Check if the kernel supports an
       option

SYNOPSIS
       int libnvmf_kernel_option_supported (struct libnvme_global_ctx *ctx ,
       const char *name , bool *supported );

ARGUMENTS
       ctx         libnvme global context

       name        Option name as the kernel lists it in /dev/nvme-fabrics,
                   e.g. "discovery", "tls", "ctrl_loss_tmo"

       supported   Set to true if the kernel supports name

DESCRIPTION
       The options are read from /dev/nvme-fabrics once per ctx. The read
       blocks while another process connects a controller.

RETURN
       0 on success, -EINVAL if an argument is NULL, -EOPNOTSUPP if the kernel
       does not list its options (Linux < 5.17), or another negative error
       code.
