svn commit: r190872 - head/sys/dev/e1000

[Mike Silbersack]

Jack, either this or some other recent change to the em driver caused it 
to stop working correctly on the e1000 virtual device inside VMware ESX. 
Unfortunately, I have not updated my 8.x VMs recently, so I don't know 
when this broke.

I got the message about an invalid MAC address.  I modified 
em_is_valid_ether_addr to always return True, but it looks like the effect 
of that was to cause the driver to load, but give the NIC a MAC of 
00:00:00:00:00:00.  However, if I manually set a MAC after that, the 
virtual NIC IS functional.  So I think the sole problem may just be that 
the code which reads the MAC is incompatible with the ESX emulation.

Do you want me to try a kernel from immediately before this change to 
confirm that this was the cause of the problem?
