Here am posting my doubts regarding MAC ID, am expecting clear explanation
1.For UDP communication custom Tiva TM4C1294ncpdt why MAC id is really required? if not there if flash some random MAC id FLASH how UDP will effect further?
2.If we want to get MAC id plz tell clear explanation in step wise.
3.if we flash FF:FF:FF:FF:FF:FF and we can work right?
4. To give Static IP any ethernet example what is the role of MAC ID?

You are asking a fundamental Ethernet question, not a MCU question. Ethernet protocol requires MAC address. I will suggest you go through the usage of MAC address from https://en.wikipedia.org/wiki/MAC_address. You can go Google search and there are tons of information about it. If you look at a Ethernet frame (see below), it consists of a six bytes of MAC destination and another six bytes of MAC source. This is like sending a mail where you specify the address that you want to send to and from who is sending.
2.If we want to get MAC id plz tell clear explanation in step wise.
Refer to https://en.wikipedia.org/wiki/MAC_address. The upper 3 nibbles of the MAC address contains the OUI that is assigned to the manufacture. Therefore, TI has a pool of MAC addresses. You need to acquire your own OUI for your company.
3.if we flash FF:FF:FF:FF:FF:FF and we can work right?
No, it will not work. You must have a valid MAC address.
4. To give Static IP any ethernet example what is the role of MAC ID?
IP address is different from MAC address. Read this article. https://www.geeksforgeeks.org/difference-between-mac-address-and-ip-address/
