The HW model implicitly decapsulates tunnels on chain 0 and sets reg_c1 with the mapped tunnel id. On miss, the packet does not have the outer header and the driver restores the tunnel information from the tunnel id. Getting reg_c1 value in software requires enabling reg_c1 loopback and copying reg_c1 to reg_b. reg_b comes up on CQE as cqe->imm_inval_pkey. Use the reg_c0 restoration rules to also copy reg_c1 to reg_B.

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.
