Sowmini Varadhan c1878f7a89 tools: psock_tpacket: block Rx until socket filter has been added and socket has been bound to loopback.
Packets from any/all interfaces may be queued up on the PF_PACKET socket
before it is bound to the loopback interface by psock_tpacket, and
when these are passed up by the kernel, they could interfere
with the Rx tests.

Avoid interference from spurious packet by blocking Rx until the
socket filter has been set up, and the packet has been bound to the
desired (lo) interface. The effective sequence is
	socket(PF_PACKET, SOCK_RAW, 0);
	set up ring
	Invoke SO_ATTACH_FILTER
	bind to sll_protocol set to ETH_P_ALL, sll_ifindex for lo
After this sequence, the only packets that will be passed up are
those received on loopback that pass the attached filter.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
