      octeontx2-pf: TC flower offload support for ICMP type and code · a8d4879d
      Geetha sowjanya authored 
      Adds tc offload support for matching on ICMP type and code.

Example usage:
To enable adding tc ingress rules
        tc qdisc add dev eth0 ingress

TC rule drop the ICMP echo reply:
        tc filter add dev eth0 protocol ip parent ffff: \
        flower ip_proto icmp type 8 code 0 skip_sw action drop

TC rule to drop ICMPv6 echo reply:
        tc filter add dev eth0 protocol ipv6 parent ffff: flower \
        indev eth0 ip_proto icmpv6 type 128 code 0 action drop

      net: phy: correctly check soft_reset ret ONLY if defined for PHY · aadbd27f
      Christian Marangi authored 
      Introduced by commit 6e2d85ec ("net: phy: Stop with excessive soft
reset").

soft_reset call for phy_init_hw had multiple revision across the years
and the implementation goes back to 2014. Originally was a simple call
to write the generic PHY reset BIT, it was then moved to a dedicated
function. It was then added the option for PHY driver to define their
own special way to reset the PHY. Till this change, checking for ret was
correct as it was always filled by either the generic reset or the
custom implementation. This changed tho with commit 6e2d85ec ("net:
phy: Stop with excessive soft reset"), as the generic reset call to PHY
was dropped but the ret check was never made entirely optional and
dependent whether soft_reset was defined for the PHY driver or not.

Luckly nothing was ever added before the soft_reset call so the ret
check (in the case where a PHY didn't had soft_reset defined) although
wrong, never caused problems as ret was init 0 at the start of
phy_init_hw.

To prevent any kind of problem and to make the function cleaner and more
robust, correctly move the ret check if the soft_reset section making it
optional and needed only with the function defined.

      Documentation: Document each netlink family · f061c9f7
      Breno Leitao authored 
      This is a simple script that parses the Netlink YAML spec files
(Documentation/netlink/specs/), and generates RST files to be rendered
in the Network -> Netlink Specification documentation page.

Create a python script that is invoked during 'make htmldocs', reads the
YAML specs input file and generate the correspondent RST file.

Create a new Documentation/networking/netlink_spec index page, and
reference each Netlink RST file that was processed above in this main
index.rst file.

In case of any exception during the parsing, dump the error and skip
the file.

Do not regenerate the RST files if the input files (YAML) were not
changed in-between invocations.

----
Changelog:

V3:
	* Do not regenerate the RST files if the input files were not
	  changed. In order to do it, a few things changed:
	  - Rely on Makefile more to find what changed, and trigger
	    individual file processing
	  - The script parses file by file now (instead of batches)
	  - Create a new option to generate the index file

V2:
	* Moved the logic from a sphinx extension to a external script
	* Adjust some formatting as suggested by Donald Hunter and Jakub
	* Auto generating all the rsts instead of having stubs
	* Handling error gracefully
