From: Rohitashv Kumar <[email protected]> show_netdevs() lists each conditionally-compiled netdev backend behind its CONFIG_* guard (CONFIG_SLIRP for "user", CONFIG_L2TPV3 for "l2tpv3", CONFIG_NET_BRIDGE for "bridge", ...). The "passt" entry was added unconditionally, so "-netdev help" advertises passt even in builds configured with --disable-passt. Trying to use it then fails with "Parameter 'type' does not accept value 'passt'", since the QAPI NetClientDriver enum member "passt" is gated by 'if': 'CONFIG_PASST'.
Guard the help entry with CONFIG_PASST so the advertised backends match those actually compiled into the binary.
