An updated iproute package that fixes various bugs is now available for Red Hat Enterprise Linux 6.
The iproute package contains networking utilities (ip and rtmon, for example) which are designed to use the advanced networking capabilities of the Linux kernel.
Prior to this update, the "ip" utility lacked the "mode" parameter support for macvtap devices. As a consequence affected users could not create macvtap devices in "bridge" or "private" modes. With this update the "ip" utility now fully supports macvtap devices along with the "mode" parameter and its options, "bridge", "private", and "vepa" (default). As a result users can now utilize macvtap functionality via the iproute package.
Prior to this update, the "ip" tool lacked the "passthru" mode parameter support for macvtap and macvlan devices. Consequently users could not create macvtap and macvlan devices in "passthru" mode. The "ip" tool now fully supports macvtap and macvlan devices along with the "mode" parameter and its options, "bridge", "private", "passthru", and "vepa" (default). As a result users can now utilize "passthru" mode as part of macvtap and macvlan functionality via the iproute package.
Prior to this update, the "tc" utility ignored GRED (Generalized RED) queue options. Consequently "tc" users could not configure certain GRED queue related parameters. With this update the "tc" utility no longer accidentally overwrites the user specified options. As a result "tc" users can now reliably define all GRED parameters.
All users of iproute are advised to upgrade to this updated package, which fixes these bugs.
