Neither is gives option to configure nor it prints the packet with FCS in 
Ethernet Header.

Typically network adapters don't allow a FCS value to be provided for tx 
packets - it is calculated by the network adapter itself. In the Rx direction, 
network adapters verify the FCS, then strip it off before handing the packet to 
the driver.

It is not possible to provide this feature with the existing libpcap/winpcap 
libraries that Ostinato uses. However, when Ostinato exports plugin support for 
adapters, this feature may be supported if the adapter plugin supports it.
