Anirudha Sarangi 10bb0f7661 lwip: Fix issue on Rx path in hadling packets with Xilkernel
This patch fixes rx packet handling issue with Xilkernel. The issue
was processing a single packet from the input queue everytime the
semaphore is released in the ISR. Now, we iterate till the queue
is completely emptied. After the ISR releases the semaphore and before
the queue is read, there could be new packets in the queue and hence can
lead to situations where there could be considerable delay in processing
a particular packet.
This patch also ensures that the ISR releases the semaphore once for
an entry into Rx ISR instead of each received packet. This enhances
performance.

embeddedsw.git - repo for standalone software

All software is version less and divided into three directories
	- lib 
		contains bsp, zynq fsbl and software services like xilisf
	- license.txt
		contains information about the various licenses and copyrights
	- XilinxProcessorIPLib
		contains all drivers
	- ThirdParty
		software from third party like light weight IP stack
	- mcap
		software for using MCAP interface on Ultra Scale boards to
		program 2nd level bitstream

Every driver/lib/apps/services has these sub-directories

1. data		- contains tcl, mdd, testapp tcl or header files used in SDK
2. doc		- documentation of source code in form of pdf or html 
3. examples	- illustrating different use cases of driver
4. src		- driver interface code implementing functionality of IP

Building FSBL from git:

FSBL has 3 directories.
	1. data - It contains files for SDK
	2. src  - It contains the FSBK source files
	3. misc - It contains miscelanious files required to 
		  compile FSBL for zc702, zc706, zed and 
		  microzed boards.
		  It also contains the ps7_init_gpl.[c/h] with gpl 
		  header in respective board directories.
		

How to compile FSBL:
	1.Go to the Fsbl src directory "lib/sw_apps/zynq_fsbl/src/"
	2. make "BOARD=<>" "CC=<>"
		a. Values for BOARD  are zc702, zc706, zed, microzed
		b. Value for CC is arm-xilinx-eabi-gcc. Default value is also same.
	3.Give "make" to compile the fsbl with BSP. By default it is 
	  built for zc702 board with arm-xilinx-eabi-gcc compiler
	4.Below are the examples for compiling for different options
		a. To generate Fsbl for zc706 board 
			i.make "BOARD=zc706"
		b.To generate Fsbl for zc702 board with debug enable 
		  and RSA support
			i.make "BOARD=zc702" "CFLAGS=-DFSBL_DEBUG_INFO -DRSA_SUPPORT"
		c.To generate Fsbl for zc706 board and compile with arm-xilinx-eabi-gcc
		  with MMC support 
			i.make "BOARD=zc706" "CC=arm-xilinx-eabi-gcc" "CFLAGS=-DMMC_SUPPORT"
