Adding Nics on PFsense guest Esxi

[IiscsiI]

Hello,

I encountered a "bug" or i don't know how to qualify it.

When i add NIC virtual hardware to my Pfsense VM and associate it to a new LAN interface everything is OK.

Then when i reboot the Pfsense the networks cards "vmxX-Y" are mixed. LAN1 nic is on LAN4, LAN5 on LAN3 etc.

i figured out that when i add a new NIC Pfsense rearrange his internal cards based on MAC address.

if you add a mac address that is "inferior" to one or more existant, bingo you have to reallocate every card to every LAN/WAN.

exemple :
before adding a nic :
em0 : 0000000000
vmx1 : 0000000002
vmx2 : 00000000f1

after addind a nic
the new nic should be like vmx3 : 0000000010
but in reality after a reboot it looks like that :
em0 : 0000000000
vmx1 : 0000000002
vmx2 : 0000000010
vmx3 : 00000000f1

it inverted vmx2 and 3.

I tried different cases on my ESXi host and every time it occurs when you add a NIC with a mac that have a number less greater that the last one.

Tested on Pfsense 2.5 and 2.6 on ESXi 7

Many thanks
