similarly to what has been done with commit 9d149045b3 ("geneve: change
from tx_error to tx_dropped on missing metadata"), avoid reporting errors
to userspace in case the kernel doesn't find any tunnel information for a
skb that is going to be transmitted: an increase of tx_dropped is enough.
tested with the following script:
# for t in ip6gre ip6gretap ip6erspan; do
> ip link add dev gre6-test0 type $t external
> ip address add dev gre6-test0 2001:db8::1/64
> ip link set dev gre6-test0 up
> sleep 30
> ip -s -j link show dev gre6-test0 | jq \
> '.[0].stats64.tx | {"errors": .errors, "dropped": .dropped}'
> ip link del dev gre6-test0
> done

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.
