This patch updates the tc-bpf.8 example application for changes to the
struct bpf_elf_map definition. In it's current form, things compile, but
the resulting object file is rejected by the verifier when attempting to
load it through tc.

This patch adds support for binding FOU ports using iproute2.
Kernel-support was added in 1713cb37bf67 ("fou: Support binding FoU
socket").
The parse function now handles new arguments for setting the
binding-related attributes, while the print function writes the new
attributes if they are set. Also, the man page has been updated.
v2->v3:
* Remove redundant ll_init_map()-calls (thanks David Ahern).
v1->v2 (all changes suggested by David Ahern):
* Fix reverse Christmas tree ordering.
* Remove redundant peer_port_set-variable, it is enough to check
peer_port.
* Add proper error handling of invalid local/peer addresses.
* Use interface name and not index.
* Remove updating fou-header file, it is already done.

DECnet belongs in the history museum of dead protocols along
with Appletalk and IPX.
Linux support has outlived its natural life and the time has

of bugs and exploits.

they can just keep to the old version of iproute2.

itself. Otherwise specifying for instance 'home -nodad' will effectively
clear the flags variable.
