All-multicast mode test
=======================

Check correct work of all-multicast mode

Checking the correct work of all-multicast mode by sending several packets with different MAC addresses.

#. Initialize EAL, preparing of **ethdev_state** Ethernet device state

#. Make sure that promiscuous mode is disabled

#. If the **is_all_mcast_mode** is ``TRUE`` then enable all-multicast mode, otherwise disable it

#. Start the Ethernet device

#. Check that a new mode was saved after start of device

#. Ensure that interface is UP on Tester side

#. Transmit three packets from **tst_if:** the first is broadcast, the second is multicast and the third is unicast, with MAC adrress is different from MAC address of the **iut_port**

#. Receive packets on port **iut_port**. Check that the first received packet matches the first sent, the second received packet matches the first sent, if **is_all_mcast_mode** is ``TRUE``, otherwise it was dropped and the third packet was dropped.
