I just bought some consumer-grade McCheap PCI-E NICs (and this was a bad idea). They both have the same MAC address. When I google it, it seems like every card of that company has the same address: 00:50:43:00:45:3e.

Shouldn't they be unique?

According to lspci it's a Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 20). Is there a way to permanently flash a new address?
