There are two main differences between Spectrum-1 and newer ASICs in terms of IP-in-IP support: 1. In Spectrum-1, RIFs representing ip6gre tunnels require two entries in the RIF table. 2. In Spectrum-2 and newer ASICs, packets ingress the underlay (during encapsulation) and egress the underlay (during decapsulation) via a special generic loopback RIF. The first difference was handled in previous patches by adding the 'double_rif_entry' field to the Spectrum-1 operations structure of ip6gre RIFs. The second difference is handled during RIF creation, by only creating a generic loopback RIF in Spectrum-2 and newer ASICs. Therefore, the ip6gre operations can be shared between Spectrum-1 and newer ASIC in a similar fashion to how the ipgre operations are shared. Rename the operations to not be Spectrum-2 specific and move them earlier in the file so that they could later be used for Spectrum-1.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
