mlx5 E-Switch mirroring is implemented as multiple destination array in
one steering table. The array currently supports only port ID as
destination actions.
This patch adds the jump action support to the array as one of
destination.
The packets can be mirrored to the port and jump to the next table in
the same destination array allowing to continue handling in the new
table.
For example:
set sample_actions 0 port_id id 1 / end
flow create 0 ingress transfer pattern eth / end actions
sample ratio 1 index 0 / jump group 1 / end
flow create 1 ingress transfer group 1 pattern eth / end actions
set_mac_dst mac_addr 00:aa:bb:cc:dd:ee / port_id id 2 / end
The flow results all the matched ingress packets are mirrored
to port id 1 and go to group 1. In the group 1, packets are modified
with the destination mac and sent to port id 2.

|
|
management schemes are supported initially:
|
|
|
|

any arbitrary header field (as well as mark, metadata or tag values):
|
|
``RTE_FLOW_ACTION_TYPE_MODIFY_FIELD``.
|
|
Supported operations are: overwriting a field with the content from
|
|
another field, addition and subtraction using an immediate value.

|
|
|
|
A new build option ``check_includes`` has been added, which, when enabled,
|
|
will perform build-time checking on DPDK public header files, to ensure none
|
|
are missing dependent header includes. This feature, disabled by default, is
|
|
intended for use by developers contributing to the DPDK SDK itself, and is
|
|
integrated into the build scripts and automated CI for patch contributions.
