LwIP port using directly RTEMS semaphores and message queues

[ragu nath]

Hi,

lwIP can be built using RTEMS Source builder now. We have  RTEMS +
lwIP OS  glue(cc.h & sys_arch.c etc) . But it uses posix lib functions
instead of RTEMS native library.
https://github.com/ragunath3252/lwip-nodrv . It's tested and  working
but not fully optimized.

https://lists.rtems.org/pipermail/devel/2015-August/012178.html is the RSB patch

lwIP is divided into architecture independent and dependent parts.
Independent part is common to all the BSP's and it can be built for
any BSP through RSB.  The dependent part contains the driver.
Currently only beaglebone black has lwIP driver.

http://ragustechblog.blogspot.in/2015/08/rtems-beaglebone-black-with-lwip.html
has details on how to build and use for beaglebone black.

Thanks,
Ragunath
