• Two new drivers (
cnic
and
bnx2i
) have been added to the kernel to introduce iSCSI support for
Broadcom®
BNX2
and
BNX2x
Network Interface Cards (NICs). (
BZ#441979
966
)
• A new device driver
igbvf
) for
SR/IOV
enabled Intel® NICs has been added to this kernel release.
This driver provides a significant performance improvement for virtualization using
SR/IOV
cards.
(
BZ#480524
967
)
• Generic Receive Offload (GRO) support has been implemented in this update, both. The GRO
system increases the performance of inbound network connections by reducing the amount of
processing done by the Central Processing Unit (CPU). GRO implements the same technique as
the Large Receive Offload (LRO) system, but can be applied to a wider range of transport layer
protocols. GRO support has also been added to a several network device drivers, including the
igb
driver for Intel® Gigabit Ethernet Adapters and the
ixgbe
driver for Intel® 10 Gigabit PCI Express
network devices. (
BZ#499347
968
)
• The
cxgb3
driver, which supports the Chelsio® 10Gb RNIC adapter, has been updated in order to
enable iSCSI TOE support. (
BZ#439518
969
)
• This kernel updates the
enic
Cisco® 10Gi Ethernet driver to version 1.0.0.933. (
BZ#484824
970
)
• This kernel updates the Atheros®
ath5k
driver. This upgrade resolves a problem encountered
by Atheros® users wherein the kernel reported an inability to wake up the MAC chip. Setting the
call to
ath5k_set_pcie()
to execute earlier in the initialization process corrects this issue.
(
BZ#479049
971
)
• Support for the Crystal Beach 3 I/O AT (Acceleration Technology) device has been included in this
kernel update. (
BZ#436039
972
,
BZ#436048
973
)
• This update upgrades the
bnx2
driver for Broadcom® network devices. The update fixes multiple
performance issues, including a kernel panic occurrence (when attempting to unload the driver while
in use) and a non-responsiveness issue (caused by call-traces initiated by network certification
processes). (
BZ#475567
974
,
BZ#476897
975
,
BZ#489519
976
)
• This release updates the Broadcom®
bnx2x
driver to version 1.48.105. (
BZ#475481
977
)
• The
igb
driver has been updated to correct a stability issue (when encountered when setting
the
mtu
parameter to less than 1K) and improve support for Intel® 82576 based devices.
(
BZ#484102
978
,
BZ#474881
979
)
• In this update the bonding driver has been updated to the latest upstream version. This update,
however has introduced
symbol/ipv6
module dependency capabilities. Therefore, if bonding
has been previously disabled (by inserting the
install ipv6 /bin/false
line in the
/etc/
modprobe.conf
file) this upgrade to the bonding driver will result in the bonding kernel module
failing to load. The
install ipv6 /bin/false
line needs to be replaced with
install ipv6
disable=1
for the module to load properly. (
BZ#462632
980
)
• The
ixgbe
driver has been updated to version 2.0.8-k2 and support the 82599 (Niantic) device has
been added. (
BZ#472547
981
)
• System freezes encountered when performing multiple remote copy programs to a system using
the Nvidia® nForce chipset has been corrected by updating the
forcedeth
driver to version 0.62.
(
BZ#479740
982
)
• The
sky2
Ethernet driver has been updated to support the Marvell® 88E8070 NIC. (
BZ#484712
