>Description:
dhclient-script is executed by dhclient for configuring interface.
After configuring the interface with ifconfig, dhclient-script checks the interface's sanity with ping command when $reason is TIMEOUT.
And back out preceding ifconfig operation, if ping command fails.

But dhclient-script uses ping command with '-w' option that isn't valid for FreeBSD's ping command.
So ping command always fails, and the interface remains unconfigured.
