DescriptionSR number
When a guest vNIC is created over the iether interface, the iether driver receives packets
from AVIO guest and handles reset request from the AVIO guest simultaneously. Due to a
QXCR1001089966
problem in the locking mechanism, interface pointers can be reset to null, which causes an
HPVM host panic.
When a guest vNIC is created over the iether interface, the iether driver holds lock too
long during AVIO packet processing. This causes an HPVM host panic.
QXCR1001090041
When a guest vNIC is created over the iether interface, HPVM guests with AVIO networking
receive duplicate multicast and broadcast packets from host.
QXCR1001085684
When heavy traffic is run on a NIC with the Intel 82546 chipset with TSO enabled, an MCA
occurs. The problem is due to known errata with NICs with this chipset. This problem occurs
QXCR1001122266
with IEther-00 version B.11.23.0909. Affected products are AB352A, AB290A, AB545A,
A7011A, A7012A.
When a guest VNIC is created over the iether interface, there is a synchronization issue
between the host freeing used buffers and the guest shutting down. This causes theHPVM host
to panic.
QXCR1001145517
When the iether module is loaded and unloaded continuously, some iether cards might
be left in unclaimed state with an error log message.
