6a30d3e349 selftests: net: Use "grep -E" instead of "egrep"
The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:
	egrep: warning: egrep is obsolescent; using grep -E
fix this using "grep -E" instead.

  sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/testing/selftests/net`

Here are the steps to install the latest grep:

  wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz
  tar xf grep-3.8.tar.gz
  cd grep-3.8 && ./configure && make
  sudo make install
  export PATH=/usr/local/bin:$PATH

5ebfb4cc30 selftests/net: toeplitz test
To verify that this hash implements the Toeplitz hash function.

Additionally, provide a script toeplitz.sh to run the test in loopback mode
on a networking device of choice (see setup_loopback.sh). Since the
script modifies the NIC setup, it will not be run by selftests
automatically.

Tested:
./toeplitz.sh -i eth0 -irq_prefix <eth0_pattern> -t -6
