Michal Maka 0c044c6b02 beaglebone ethernet improvements 
. added enable interrupts routine at the HW init stage
	. remove workaround, obsoleted by libnetdriver change
	. change netconf.sh to allow configuring this driver,
	  changed README.txt to reflect this

*                           INFORMATION:                                       *

README file for the LAN8710A ethernet board driver for BeagleBone Rev. A6a

created July 2013, JPEmbedded (info@jpembedded.eu)

--------------------------------------------------------------------------------
*                           INSTALLATION:                                      *
--------------------------------------------------------------------------------
To install LAN8710A for BeagleBone under MINIX you execute 'netconf' as
usual.  Select the LAN8710A driver from the list.  Restart the system
and the driver should work.

--------------------------------------------------------------------------------
*                                 TESTS:                                       *
--------------------------------------------------------------------------------
Driver was tested using various tools, i. e.
* fetch - downloading file from the Internet and also local server. Every file
	  downloaded well, but speed was about 50-200 kB/s.
* ftp - downloading and uploading 20 MB file completed.
* ping - checking connection between BeagleBone and computer passed using stan -
	 dard  settings,  when we set ping  requests interval  to 200 ms it also
	 passed. But  with 20 ms  and 2 ms  driver dropped some packets (20 ms -
	 about 20% loss, 2 ms - 50% loss).
* udpstat, hostaddr, dhcpd, ifconfig, arp gave proper results.
Tests passed, so driver meets the requirements of ethernet driver.

*                                LIMITATION:                                   *

Download speed:  50-200 kB/s
Low bandwidth is probably caused by memory copy functions. Standard Linux driver 
copies packets data directly to destination buffer using DMA. Minix driver needs
to do a safe copy (sys_safecopyfrom and sys_safecopyto) from local buffer to the 
system buffer. This operation slows down the whole driver.
