Currently virtual router ID element is broken to two sub-elements - 'VIRT_ROUTER_LSB' and 'VIRT_ROUTER_MSB'. It was broken as this field is broken in 'ipv4_4' flex key which is used for IPv4 in Spectrum < 4. For Spectrum-4, we use 'ipv4_4b' flex key which contains one field for virtual router, this key is not supported in older ASICs. Add 'ipv4_5' flex key which is supported in all ASICs and contains one field for virtual router. Then there is no reason to use 'VIRT_ROUTER_LSB' and 'VIRT_ROUTER_MSB', remove them and add one element 'VIRT_ROUTER' for this field. The motivation is to get rid of 'ipv4_4' flex key, as it might be chosen for IPv6 multicast forwarding region. This will not allow the improvement in a following patch. See more details in the cover letter and in a following patch.

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.
