I've come across  some issue with ixgbe, loaded in VMWare(esxi).
I created number of VFs per interface and handed them to the VM via PCI 
passthrough mode(vSphere), but the problem is to configure L2 switch on 82599, 
to make it sorting packets upon VFs, according to the vlan or mac address, as 
result, I observe all packets end up in PF. I tried to set vlan filter from VM 
via the ixgbevf(via the Mailbox), but it seems to fail with error(8021q module 
is loaded in VM). I think if the communication between VF and PF works, when 
ixgbe is being loaded and MAC addresses are assigned to the VFs, it must inform 
82599 via PF(using Mailbox) about the mapping and as result L2 
Classifier/Switch knows about new assigned mac address and its VF, where the 
incoming packet would be directed. 
Any info about configuring L2 Switch on 82599 in Virtual Environment would be 
appreciated. 
Thanks,Maksim
