3.5 Networking

The following networking features, bug fixes, and enhancements are included in this update:

  • Control switch for offloading VXLAN and Geneve tunnels added to RHCK.  This change to the ethtool utility can only be used with drivers that support this functionality, such as the new Geneve driver in the latest RHCK. A new control switch in the utility can be used to enable or disable offloading of VXLAN and Geneve tunnels to network cards.

  • Geneve driver version updated to 4.14.  The updated version the Geneve driver includes a number of bug fixes and enhancements from the previous version.

  • Search capability for IPTABLES_SYSCTL_LOAD_LIST modifications expanded to /etc/sysctl.d The search capability for IPTABLES_SYSCTL_LOAD_LIST modifications has been expanded to include the systctl.d directory. Previously, only the /etc/sysctl.conf file was searched for changes. This enhancement ensures that any user-provided files in /etc/sysctl.d/ are correctly accounted for when the iptables service restarts.

  • VXLAN updated to version 4.14.  The updated version of the Virtual Extensible LAN (VXLAN) feature includes a number of bug fixes and enhancements from the previous version.
