Identify and remediate systems affected by this advisory.
Topic
An enhanced ethtool package that adds support for GRO options is now
available.
Description
Ethtool allows querying and changing of ethernet card settings, such as
speed, port, autonegotiation, and PCI locations.
This updated package adds the following enhancement:
- generic receive offload (GRO) has been added to some network drivers in
Red Hat Enterprise Linux 5.4. GRO aggregates packets before they're
processed by the rest of the stack. This allows TCP performance to be
greatly enhanced at high speeds. In particular, it's crucial for good 10GbE
performance. With GRO enabled, you should observe higher throughput, lower
CPU utilization of network traffic, or both; especially with smaller
message sizes.
The kernel in Red Hat Enterprise Linux 5.4 allows users to manually control
whether GRO is enabled for supported ethernet adapters. This updated
ethtool provides a command-line interface -- "ethtool -k" -- for setting
and querying that flag. (BZ#509398)
All ethtool users should upgrade to this updated package which adds this
capability.
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
