ixgbevf Driver Does Not Properly Report a Link State Change to the MAC Layer (21629053)

This issue was fixed in Oracle Solaris 11.3.2.4.

If you reboot the root domain with I/O Resiliency (IOR) enabled (that is, logical domains failure policy set to ignore) the I/O domain might fail to initiate an ixbgevf network interface.

For example, before rebooting non primary root domain (NPRD), type:

# ipmpstat -i
INTERFACE   ACTIVE  GROUP       FLAGS     LINK      PROBE     STATE
net1        yes     ipmp0       --mbM--   up        disabled  ok
net7        yes     ipmp0       -------   up        disabled  ok

# dladm show-phys
LINK              MEDIA                STATE      SPEED  DUPLEX    DEVICE

net0              Ethernet             up         0      unknown   vnet0
net7              Ethernet             up         10000  full      ixgbevf7
net1              Ethernet             up         10000  full      ixgbevf4

After rebooting the NPRD, type:

# ipmpstat -i
INTERFACE   ACTIVE  GROUP       FLAGS     LINK      PROBE     STATE
net1        no      ipmp0       -------   down      disabled  failed
net7        yes     ipmp0       --mbM--   up        disabled  ok
# dladm show-phys                          
LINK              MEDIA                STATE      SPEED  DUPLEX    DEVICE

net0              Ethernet             up         0      unknown   vnet0
net7              Ethernet             up         10000  full      ixgbevf7
net1              Ethernet             down       10000  full      ixgbevf4

Recovery: Perform these steps.

1. Unplumb and plumb the failed interface.

   # ipadm delete-ip net1
   # ipadm create-ip net1

2. Add the device into the ipmp group again.

   # ipadm add-ipmp -i net1 ipmp0
