MPLS over UDP is supported by adding a rule on a representor net device
which does tunnel_key set, push mpls and forward to a baredup device. At
the hardware level we use a packet_reformat_context object to do the
encapsulation of the packet.
The resulting packet looks as follows (left side transmitted first):
outer L2 | outer IP | UDP | MPLS | inner L3 and data |
Example usage:
tc filter add dev $rep0 protocol ip prio 1 root flower skip_sw \
action tunnel_key set src_ip 8.8.8.21 dst_ip 8.8.8.24 id 555 \
dst_port 6635 tos 4 ttl 6 csum action mpls push protocol 0x8847 \
label 555 tc 3 action mirred egress redirect dev bareudp0
This is how the filter is shown with tc filter show:
tc filter show dev enp59s0f0_0 ingress
filter protocol ip pref 1 flower chain 0
filter protocol ip pref 1 flower chain 0 handle 0x1
eth_type ipv4
skip_sw
in_hw in_hw_count 1
action order 1: tunnel_key set
src_ip 8.8.8.21
dst_ip 8.8.8.24
key_id 555
dst_port 6635
csum
tos 0x4
ttl 6 pipe
index 1 ref 1 bind 1
action order 2: mpls push protocol mpls_uc label 555 tc 3 ttl 255 pipe
index 1 ref 1 bind 1
action order 3: mirred (Egress Redirect to device bareudp0) stolen
index 1 ref 1 bind 1

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.
