--------------------------------------------------------------------------
SRU Justification:
[Impact]
* Without Kernel support for the Dummy net driver, it is not possible
to successfully run selftests that use it. This includes as per this
bug net/fib_nexthop_nongw.sh, but also could potentially include other
such as rtnetlink.sh, fib_rule_tests.sh, forwarding/* etc.
[Fix]
* Custom patch to enable CONFIG_DUMMY=m
[Test Plan]
* Before the fix, the net/fib_nexthop_nongw.sh script will fail in the
specific line which does
$ ip -n h1 link add name eth0 type dummy
Error: Unknown device type.
After the fix it does not fail.
[Where problems could occur]
* The regression can be considered as low, since we are adding
functionality not previously present.
[Other Info]
* There does not seem to be a historical reason for removing it from
linux-kvm.
