* tunnels: Enable UDP checksum computation for Geneve and VXLAN.Jesse Gross2015-03-241-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | The kernel module can already support outer UDP checksums for Geneve and VXLAN using the standard checksum flag in tunnel metadata. This makes userspace aware of the capability so that users can enable it on tunnel ports. There is a complication in that there is no way for userspace to probe or detect if the kernel does not support this capability in order to warn the user. In this case, connectivity will appear to function normally but packets will not be checksum protected. This is mainly an issue for VXLAN which has existed in the kernel for a some time without checksum support - while there are also a few kernel versions that support Geneve only without checksums, they are much less common. There isn't a particularly good solution to the compatibility issue without introducing a larger capabilities structure. However, UDP checksums are likely to be used only rarely at this point in time and the VXLAN spec (where the main problem lies) recommends against them. Therefore, this is considered to be an advanced user feature and we settle for just documenting the issue.

* doc: Convert docs to Markdown languageThomas Graf2014-10-281-0/+1645
Converts the majority of docs over to use the Markdown language for pretty printing on GitHub. It's a rough first convertion without exploiting the full potential of Markdown at this point. Section titles and indentation are fixed as needed. Minimal docs interlinking is added. Signed-off-by: Thomas Graf <tgraf@noironetworks.com> Signed-off-by: Ben Pfaff <blp@nicira.com>
