* Now the encapsulation is not supported for mlx5 VFs. When we try to
offload that action, the -EINVAL is returned, but not -EOPNOTSUPP.
This patch changes the returned value and ignore to confuse user.
The command is shown as below [1].
* When max modify header action is zero, we return -EOPNOTSUPP
directly. In this way, we can ignore wrong message info (e.g.
"mlx5: parsed 0 pedit actions, can't do more"). This happens when
offloading pedit actions on mlx(cx4) VFs. The command is shown as below [2].
For example: (p2p1_0 is VF net device)
[1]
$ tc filter add dev p2p1_0 protocol ip parent ffff: prio 1 flower skip_sw \
src_mac e4:11:22:33:44:01 \
action tunnel_key set \
src_ip 1.1.1.100 \
dst_ip 1.1.1.200 \
dst_port 4789 id 100 \
action mirred egress redirect dev vxlan0
[2]
$ tc filter add dev p2p1_0 parent ffff: protocol ip prio 1 \
flower skip_sw dst_mac 00:10:56:fb:64:e8 \
dst_ip 1.1.1.100 src_ip 1.1.1.200 \
action pedit ex munge eth src set 00:10:56:b4:5d:20

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.
