Kernel now supports attaching XDP programs in the driver
and hardware at the same time. Print that information
correctly.
In case there are multiple programs attached kernel will
not provide IFLA_XDP_PROG_ID, so don't expect it to be
there (this also improves the printing for very old kernels
slightly, as it avoids unnecessary "prog/xdp" line).
In short mode preserve the current outputs but don't print
IDs if there are multiple.
6: netdevsim0: <BROADCAST,NOARP> mtu 1500 xdpoffload/id:11 qdisc [...]
and:
6: netdevsim0: <BROADCAST,NOARP> mtu 1500 xdpmulti qdisc [...]
ip link output will keep using prog/xdp prefix if only one program
is attached, but can also print multiple program lines:
prog/xdp id 8 tag fc7a51d1a693a99e jited
vs:
prog/xdpdrv id 8 tag fc7a51d1a693a99e jited
prog/xdpoffload id 9 tag fc7a51d1a693a99e
JSON output gains a new array called "attached" which will
contain the full list of attached programs along with their
attachment modes:
"xdp": {
"mode": 3,
"prog": {
"id": 11,
"tag": "fc7a51d1a693a99e",
"jited": 0
},
"attached": [ {
"mode": 3,
"prog": {
"id": 11,
"tag": "fc7a51d1a693a99e",
"jited": 0
}
} ]
},
In case there are multiple programs attached the general "xdp"
section will not contain program information:
"xdp": {
"mode": 4,
"attached": [ {
"mode": 1,
"prog": {
"id": 10,
"tag": "fc7a51d1a693a99e",
"jited": 1
}
},{
"mode": 3,
"prog": {
"id": 11,
"tag": "fc7a51d1a693a99e",
"jited": 0
}
} ]
},

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. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. 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.
