====================
Currently, bpftool net only supports dumping progs attached on the
interface. To attach XDP prog on interface, user must use other tool
(eg. iproute2). By this patch, with `bpftool net attach/detach`, user
can attach/detach XDP prog on interface.
# bpftool prog
16: xdp name xdp_prog1 tag 539ec6ce11b52f98 gpl

20: xdp name xdp_fwd_prog tag b9cb69f121e4a274 gpl

# bpftool net attach xdpdrv id 16 dev enp6s0np0
# bpftool net
xdp:
enp6s0np0(4) driver id 16
# bpftool net attach xdpdrv id 20 dev enp6s0np0 overwrite
# bpftool net
xdp:
enp6s0np0(4) driver id 20
# bpftool net detach xdpdrv dev enp6s0np0
# bpftool net
xdp:
While this patch only contains support for XDP, through `net
attach/detach`, bpftool can further support other prog attach types.
XDP attach/detach tested on Mellanox ConnectX-4 and Netronome Agilio.
---
Changes in v5:
- fix wrong error message, from errno to err with do_attach/detach
Changes in v4:
- rename variable, attach/detach error message enhancement
- bash-completion cleanup, doc update with brief description (attach
types)
Changes in v3:
- added 'overwrite' option for replacing previously attached XDP prog
- command argument order has been changed ('ATTACH_TYPE' comes first)
- add 'dev' keyword in front of <devname>
- added bash-completion and documentation
Changes in v2:
- command 'load/unload' changed to 'attach/detach' for the consistency

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
