Daniel Machon says: ==================== This patch series makes use of the newly introduced [1] DCB_APP_SEL_PCP selector, for PCP/DEI prioritization, and DCB_ATTR_IEEE_APP_TRUST attribute for configuring per-selector trust and trust-order. ======================================================================== New parameter "pcp-prio" to existing "app" subcommand: ======================================================================== A new pcp-prio parameter has been added to the app subcommand, which can be used to classify traffic based on PCP and DEI from the VLAN header. PCP and DEI is specified in a combination of numerical and symbolic form, where 'de' (drop-eligible) means DEI=1 and 'nd' (not-drop-eligible) means DEI=0. Map PCP 1 and DEI 0 to priority 1 $ dcb app add dev eth0 pcp-prio 1nd:1 Map PCP 1 and DEI 1 to priority 1 $ dcb app add dev eth0 pcp-prio 1de:1 ======================================================================== New apptrust subcommand for configuring per-selector trust and trust order: ======================================================================== This new command currently has a single parameter, which lets you specify an ordered list of trusted selectors. The microchip sparx5 driver is already enabled to offload said list of trusted selectors. The new command has been given the name apptrust, to indicate that the trust covers APP table selectors only. I found that 'apptrust' was better than plain 'trust' as the latter does not indicate the scope of what is to be trusted. Example: Trust selectors dscp and pcp, in that order: $ dcb apptrust set dev eth0 order dscp pcp Trust selectors ethtype, stream-port and pcp, in that order $ dcb apptrust set dev eth0 order ethtype stream-port pcp Show the trust order $ dcb apptrust show dev eth0 order order: ethtype stream-port pcp A concern was raised here [2], that 'apptrust' would not work well with matches(), so instead strcmp() has been used to match for the new subcommand, as suggested here [3]. Same goes with pcp-prio parameter for dcb app. The man page for dcb_app has been extended to cover the new pcp-prio parameter, and a new man page for dcb_apptrust has been created.

How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. include/uapi
This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
