DescriptionSR number
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
with IEther-00 version B.11.31.0909. Affected products are AB352A, AB290A, AB545A,
A7011A, A7012A.

When traffic is run on a NIC with the Intel 82575 chipset with TSO enabled, a system panic
occurs with "iether_post_tdesc_tso" function on top of the stack trace. This problem occurs
with IEther-00 version B.11.31.1003. Affected products are AD221A, AD222A, AD393A.

Typo error in the nwmgr --st subsys -c <lanppa> output .QXCR1001062966
The command nwmgr -s -A all --sa --fr current -c lan<ppa> on a PCIe
interface controlled by the iether driver fails with the following error message: New
512byte transmit buffer size limit = ERROR: Unsupported attribute.
QXCR1001063280
Typo error in the nwmgr_iether(1M) man page.QXCR1001062969
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.
QXCR1001075909
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
problem in the locking mechanism, interface pointers can be reset to null, which causes an
HPVM host panic.
QXCR1001075915
When a guest vNIC is created over the iether interface, HPVM guests with AVIO networking
receive duplicate multicast and broadcast packets from host.
