8.52. ethtool 8.52.1. RHBA-2014:1421 - ethtool bug fix and enhancement update Updated ethtool packages that fix several bugs and add one enhancement are now available for Red Hat Enterprise Linux 6. Ethtool is a utility that enables querying and changing settings such as speed, port autonegotiation, PCI locations, and checksum offload on many network devices, especially on ethernet devices. Bug Fixes BZ# 1003891 Previously, the ethtool utility did not support the Backplane link type. As a consequence, ethtool did not return "supported link modes" and "advertised link modes" on be2net-based devices. With this update, the support for Backplane has been added, and ethtool now returns "supported link modes" and "advertised link modes" as expected. BZ# 1010843 Previously, the ethtool utility did not correctly communicate with the network device driver when attempting to set Large Receive Offload (LRO) options. Consequently, it was not possible to set the LRO options on devices supporting LRO. With this update, ethtool has been fixed to communicate correctly with the network device driver, and the LRO options can now be set on network devices. BZ# 1018367 Due to a change to the ixgbe driver, the "ethtool -d" command in non-raw mode stopped providing output. As a consequence, "ethtool -d" could not be used to examine the state of ixgbe devices. To fix this bug, ethool has been changed to work with the new ixgbe device driver, and the "ethtool -d" command in non-raw mode can now be used again on the ixgbe devices. In addition, this update provides the following Enhancement BZ# 1105589 With this update, the ethtool utility supports the Medium Dependent Interface Crossover (MDI-X) mode setting on the e1000, e1000e, and igb drivers. Users of ethtool are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.
