Merge branch 'new_eth' of http://gnuradio.org/git/matt into new_eth
* 'new_eth' of http://gnuradio.org/git/matt:
properly set the address filter
stop sending short ethernet command packets.
Fix problem with commands timing out (specifically stop_rx_streaming)
Fix race condition that caused commands such as stop_rx_streaming to fail.
Fixing a line in the clock recovery algorithm. This works with a bit larger error than there proably should be.
Better fix for broken AC_PROG_F77 macro
Fix Python header check failure due to invalid cached state
waterfall and fft use a common autoscale function
Fix so that the waterfall texture is initialized with a buffer of the same size.
Modifications to usrp2 source and sink so that set center freq is called afer set lo offset.
Modifications to the usrp blocks and wrapper so that the lo offset is set with the lo frequency.
Removed subversion related configuration info.
Expand frequency ranges to match hardware capability.
Modified log power fft block so ref scale is peak to peak.
Adding clock sync algorithm using PFB. This works, but needs a bit more work.

After fixing the race, this change uses Tom's idea to stop enqueuing
data when trying to stop, and adds a new flush_rx_samples method
to drop any samples that may have already been accumulated.
I ran Tom's test case 500 times with 0 failures ;-)

Fix so that the waterfall texture is initialized with a buffer of the same size.
If the fft size was a non power of two, the buffer would be a different size.
This would cause a segfault. Particularly because fft_window was throwing out a bin.
Merge branch 'wxgui' from http://gnuradio.org/git/jblum.git into master
* Modified log power fft block so ref scale is peak to peak.
* Tweaked fft sink autoscale routine to come up with better numbers.
* Modified scope sink ac couple block to use constant tap. The previous
tap calculation would cause failure for very small sample rates.

Merge utils from http://gnuradio.org/git/trondeau.git
Added files to Makefile.am for distribution.
Added colorbar to spectrogram for magnitude measurement.
Fixed spectrogram plotting axis.
Adding a spectrogram plot. The axis need work.
GR plotter tool handles end of file and files shorter than the block length.
Manages window/filter types better. Disables filter types if the designing algorithm doesn't support it (no RRC or Gaussian for equiripple filters).
User messages if PyQt and PyQwt are not installed (or found).
Setting validators for all edit boxes.
Fixing tab order.
Adding display for the number of taps in the filter.
Adding equiripple band reject filter to filter design app.
Adding P-M version of band reject filter.
Fixed documentation for optfir band pass filters.
Added routine for optfir equiripple filter design code to create complex bandpass filters. Also adds this ability to the filter designer.
Added design for Guassian filters.
Added design for RRC filters.
Added Band Notch filter
Adding complex bandpass filter design (for windowed filters only).
Adding plotting of group delay.
Adding labels to the plots.

Add blobs and shorthand pmt pseudo-constructors.
blobs == Binary Large Object. Very handy for passing around
uninterpreted data. The shorthand constructors were implemented by
overloading the pmt_t mp(foo) function in the pmt namespace.
I originally called "mp" "pmt", but that caused a conflict with the
pmt namespace.

Added reset method to gr_head and gr_vector_sink. This allows graphs
containing these blocks to be run more than once with user control
over when the reset of the counter and sink occurs.
