OpenNIC MAC address varies on each insmod of onic driver

[attdone]

Hi Team,
I am currently using OpenNIC in Alveo u200, as I could see the MAC address are changing everytime.
At first, insmod onic.ko
The MAC value of interfaces enp8s0f0, enp8s0f1 were 00:0a:35:e9:e5:68 and 00:0a:35:87:5b:ee respectively.
I removed the driver using rmmod onic and restarted the driver after some seconds, insmod onic.ko. At this moment the MAC address is different i.e., 00:0a:35:fb:a7:0c and 00:0a:35:6a:0c:32 for enp8s0f0 and enp8s0f1.

When I run TestPMD DPDK command (after dpdk-devbind.py -b vfio-pci enp8s0f0) I could see the MAC address is 15:16:17:18:19:1A. Why the MAC didnot get updated?

Please let me know why the MAC keeps changing and let me how to fix this issue. Any suggestions would be highly appreciated.
Thanks in advance.

There's a section within onic_main.c, where it assigns a random value for the source MAC address (search for "random"). You can edit this to be some other value:

	memset(&saddr, 0, sizeof(struct sockaddr));
	memcpy(saddr.sa_data, onic_default_dev_addr, 6);
	get_random_bytes(saddr.sa_data + 3, 3);
	onic_set_mac_address(netdev, (void *)&saddr);
