This patchset introduces actions infrastructure changes which allows the
user to choose between different action implementations based on CPU ISA
by using different commands. The infrastructure also provides a way to
check the correctness of the ISA optimized action version against the
scalar version.
This series also introduces optimized versions of the following actions:
- push_vlan
- pop_vlan
- set_masked eth
- set_masked ipv4
Below is a table indicating the relative performance benefits for these
actions.
+-----------------------------------------------+-------------------+-----------------+
| Actions | Salar with series | AVX with
series |
+-----------------------------------------------+-------------------+-----------------+
| mod_dl_dst | 1.04x | 1.15x
|
+-----------------------------------------------+-------------------+-----------------+
| push_vlan | 1.10x | 1.23x
|
+-----------------------------------------------+-------------------+-----------------+
| strip_vlan | 1.05x | 1.14x
|
+-----------------------------------------------+-------------------+-----------------+
| mod_ipv4 1 x field | 1.04x | 1.04x
|
+-----------------------------------------------+-------------------+-----------------+
| mod_ipv4 4 x fields | 1.04x | 1.23x
|
+-----------------------------------------------+-------------------+-----------------+
| strip_vlan + mod_dl_dst + mod_ipv4 4 x fields | 1.06x | 1.36x
|
+-----------------------------------------------+-------------------+-----------------+
