[ Upstream commit218d05ce32] In some case, we may use multiple pedit actions to modify packets. The command shown as below: the last pedit action is effective. $ tc filter add dev netdev_rep parent ffff: protocol ip prio 1 \ flower skip_sw ip_proto icmp dst_ip 3.3.3.3 \ action pedit ex munge ip dst set 192.168.1.100 pipe \ action pedit ex munge eth src set 00:00:00:00:00:01 pipe \ action pedit ex munge eth dst set 00:00:00:00:00:02 pipe \ action csum ip pipe \ 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 To fix it, we add max_mod_hdr_actions to mlx5e_tc_flow_parse_attr struction, max_mod_hdr_actions will store the max pedit action number we support and num_mod_hdr_actions indicates how many pedit action we used, and store all pedit action to mod_hdr_actions.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
