Merge branch 'new_eth' of http://gnuradio.org/git/matt into master
* 'new_eth' of http://gnuradio.org/git/matt: (42 commits) Fix warnings, mostly from implicitly defined wires or unspecified widths fullchip sim now compiles again, after moving eth and models over to new simple_gemac remove unused opencores remove debugging code no idea where this came from, it shouldn't be here Copied wb_1master back from quad radio Remove old mac. Good riddance. remove unused port More xilinx fifos, more clean up of our fifos might as well use a cascade fifo to help timing and give a little more capacity fix a typo which caused tx glitches Untested fixes for getting serdes onto the new fifo system. Compiles, at least Implement Eth flow control using pause frames parameterized fifo sizes, some reformatting remove unused old style fifo allow control of whether or not to honor flow control, adds some debug lines debug the rx side no longer used, replaced by newfifo version remove special last_line adjustment from ethernet port Firmware now inserts mac source address value in each frame. ...
