Stephen Hemminger says: ==================== veth and GSO maximums This is the more general way to solving the issue of GSO limits not being set correctly for containers on Azure. If a GSO packet is sent to host that exceeds the limit (reported by NDIS), then the host is forced to do segmentation in software which has noticeable performance impact. The core rtnetlink infrastructure already has the messages and infrastructure to allow changing gso limits. With an updated iproute2 the following already works: # ip li set dev dummy0 gso_max_size 30000 These patches are about making it easier with veth. ==================== Signed-off-by: David S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
