VLAN on Virtual Functions (SPARC LDOM)

This example comes from a SuperCluster M7 which runs an SVA version not able to apply VLANs using the GUI: 

root@primary:~# ldm stop ssccn1-io-io-dom
root@primary:~# ldm set-io vid=1620,1621,1680,1690 alt-mac-addrs=auto,auto,auto,auto,auto /SYS/CMIOU3/PCIE2/IOVNET.PF0.VF0
root@primary:~# ldm set-io vid=1620,1621,1680,1690 alt-mac-addrs=auto,auto,auto,auto,auto /SYS/CMIOU3/PCIE2/IOVNET.PF1.VF0
root@primary:~# ldm start ssccn1-io-io-dom

I/O Domain (Guest-Domain): 

 
root@io-dom:~# ipadm show-addr
root@io-dom:~# ipadm delete-ipmp -f sc_ipmp0
root@io-dom:~# ipadm delete-ip net0
root@io-dom:~# ipadm delete-ip net1
root@io-dom:~# dladm create-vlan -l net0 -v 1680 net0_1680
root@io-dom:~# dladm create-vlan -l net1 -v 1680 net1_1680
root@io-dom:~# ipadm create-ip net0_1680
root@io-dom:~# ipadm create-ip net1_1680
root@io-dom:~# ipadm create-ipmp -i net0_1680 -i net1_1680 sc_ipmp0   
root@io-dom:~# ipadm set-ifprop -p standby=off -m ip net0_1680
root@io-dom:~# ipadm set-ifprop -p standby=on -m ip net1_1680
root@io-dom:~# ipadm create-addr -T static -a 192.168.180.101/24 sc_ipmp0/v4

@SPECTRE

Like already mentioned and updated in my previous post Meltdown and Spectre on SPARC we got some patches from Oracle for Solaris:
Oracle Support Document 2349278.1 (Oracle Solaris on SPARC — Spectre (CVE-2017-5753, CVE-2017-5715) and Meltdown (CVE-2017-5754) Vulnerabilities)

Will update some performance impacts if I see them… please share your experiences about performance issues with those patches….

[Update]
Oracle published a new MOS article about the impact:
Oracle Support Document 2386271.1 (Performance impact of technical mitigation measure against vulnerability CVE-2017-5715 (Spectre v2) on SPARC Servers)

Like on other architectures 2-10% … heard some very bad news from customers using older Intel boxes with up to 70% IO loss… real world examples will be interesting…
