Chapter 1. Package Updates
132
the
cxgb3
,
iw_nes NES iWARP
,
mthca
and
qlgc_vnic
drivers, the
rdma
headers and SDP and
SRP protocols to the OpenFabrics Enterprise Distribution (OFED) 1.4.1 versions. (
BZ#476301
951
)
• Support has been added for Mellanox ConnectX based 10GigE Ethernet cards. This support
required updates of the
mlx4
,
mlx4_ib
and
mlx4_core
drivers as well as the inclusion of the
hybrid
mlx4_en
driver. (
BZ#477065
952
and
BZ#456525
953
)
• Problems with connectivity (using eHCA adapters) and various scripting issues have been rectified
with updates to
eHCA
and
IPoIB
drivers in this release. (
BZ#466086
954
)
• Infiniband driver updates, incorporated with the OFED 1.4.1 release upgrade, have rectified
kernel panic issues encountered when removing
ib_ipath
module while running HXT HCAs
(
BZ#230035
955
). This upgrade also resolved failed
RDMA latencytest
and
perftest
processes
run with QLogic IB. (
BZ#480696
956
)
• This update includes a patch that corrects a network port ordering problem encountered on systems
using HP
ProLiant
or
xw460c
blade processors. (
BZ#490068
957
)
• A comprehensive series of patches have been included in this update to add and/or improve
virtualization features. A complete list (including explanatory notes) can be found at
BZ#493152
958
.
• Several bugfixes and updates available for HP's Integrated Lights-Out (
hpilo
) product have been
ported into this kernel release. A complete list can be found here;
BZ#488964
959
.
• PCI device drivers enable devices using
pci_enable()
, which enables regions probed by the
device's Base Address Register (BAR). On larger servers I/O port resources may not be assigned
to all the PCI devices due to coded limitations and base register fragmentation. This update adds,
removes and refines multiple functions so as to improve resource allocation around free I/O ports.
(
BZ#442007
960
)
• Three new patches have been added to this kernel to improve the passing of PCI devices between
a virtual machine and its host. These patches first bind the device in question to a dummy
driver (
pcistub.ko
) to prevent the host machine using it. Then, once the guest is finished with
the device,
drivers_probe
prompts the kernel to re-load the true driver for that device and
remove_id
removes the relevant entry from the dynamic ID list. These new features operate
successfully in both KVM and Xen virtualization environments. (
BZ#491842
961
)
• An updated driver for the Davicom
DM9601
Ethernet Adaptor has been included in this release.
The new driver corrects previous unreliability using this device and other devices using the same
chipset. (
BZ#471800
962
)
• This kernel release includes a patch to improve Huawei
EC121
USB 3G modem support.
(
BZ#485182
963
)
• The driver for Apple Intel® hardware configurations (
efifb
) has been updated, providing various
performance improvements when running this release on these machines. (
BZ#488820
964
)
1.110.9.9. Network Driver Updates
Updates to Network-related drivers:
• This update adds a feature to support bonding over
IPoIB
interfaces. A new
ib-bond
package
has been added to the kernel to allow multiple link HA and improve load balancing and aggregation
performance. (
BZ#430758
