Add new pcp-prio parameter 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
Internally, PCP and DEI is encoded in the protocol field of the dcb_app
struct. Each combination of PCP and DEI maps to a priority, thus needing
a range of 0-15. A well formed dcb_app entry for PCP/DEI
prioritization, could look like:
struct dcb_app pcp = {
.selector = DCB_APP_SEL_PCP,
.priority = 7,
.protocol = 15
}
For mapping PCP=7 and DEI=1 to Prio=7.
Also, three helper functions for translating between std and non-std APP
selectors, have been added to dcb_app.c and exposed through dcb.h.

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.
