Subject: [RFC PATCH iproute2-next 0/2] Add pcp-prio and new APPTRUST subcommand
This patch series implements the interfaces of the kernel side patch series:
https://lore.kernel.org/netdev/20220908120442.3069771-1-daniel.machon@microchip.com/#t
This is posted RFC as the kernel side is not ready to be merged yet.
- New pcp-prio parameter has been added to existing app subcommand.
- New apptrust subcommand with parameter trust-order has been added.
Patch #1 Introduces a new pcp-prio parameter to the app subcommand. This new
parameter uses the array parameter to map a pcp and dei value to priority.
The key is the PCP and DEI value in numerical and symbolic form, respectively.
Also dcb-app.8 man page has been extended to describe the new parameter.
Example:
Map PCP 1 and DEI 0 to priority 1
$ dcb app add dev eth0 pcp-prio 1:1
Map PCP 1 and DEI 1 to priority 1
$ dcb app add dev eth0 pcp-prio 1de:1
Patch #2 Introduces a new apptrust subcommand. This new subcommand has currently
one parameter: trust-order. It lets you specify a list of trusted selectors, in
order of precendence. Also a new dcb-apptrust.8 man page has been added, to
describe the ned subcommand and its parameter.
Example:
Trust selectors dscp and pcp, in that order:
$ dcb apptrust set dev eth0 dscp pcp
Trust selectors ethertype, stream and pcp, in that order
$ dcb apptrust set dev eth0 eth stream pcp
Show the trust order
$ dcb apptrust show dev eth0
trust-order: eth stream pcp
Both patches makes changes to the uapi dcbnl.h kernel header. Changes to kernel
headers is probably not dealt with this way?
Daniel Machon (2):
dcb: add new pcp-prio parameter to dcb app
dcb: add new subcommand for apptrust object
