Up until now we used the hardware's defaults for multipath hash computation. This patch aligns the hardware's multipath parameters with the kernel's. For IPv4 packets, the parameters are determined according to the 'fib_multipath_hash_policy' sysctl during module initialization. In case L3-mode is requested, only the source and destination IP addresses are used. There is no special handling of ICMP error packets. In case L4-mode is requested, a 5-tuple is used: source and destination IP addresses, source and destination ports and IP protocol. Note that the layer 4 fields are not considered for fragmented packets. For IPv6 packets, the source and destination IP addresses are used, as well as the flow label and the next header fields.

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.
