Read through the comments in /etc/rc.d/netwait as that should do what
you're looking for (wait until the interface is active or wait until you
get a ping response from an IP before continuing with network
configuration).

is there a way to wait for the 'carrier up' of the interface before route reconfiguration?
My use case is a server with 2 Mellanox and a Lagg. The 2 mce interfaces are UP in milliseconds but
the lagg interface takes a few seconds to be UP, and the routing service says 'Network unreachable'.
The subnet is a /32 and the gateway need a static route like:
# /etc/rc.conf.d/netif
cloned_interfaces="lagg0"
ifconfig_mce0="up"
ifconfig_mce1="up"
ifconfig_lagg0="laggproto lacp laggport mce0 laggport mce1 198.51.100.1 netmask 255.255.255.255 mtu 1500"
# /etc/rc.conf.d/routing
route_defaultgw="-host 203.0.113.1 -link -interface lagg0"
defaultrouter="203.0.113.1"
static_routes="defaultgw"
If I run 'service netif restart && sleep 5 && service routing restart', everything is ok.
I didn't find any options for that, and was thinking about a patch in the routing script.
