[genode-main] network implementation example (for Parallella Board)

[Rank Jerome]

Thank you for the info. I am still just evaluating. I'll call then 
again regarding my research :)

thanks and regards,
Jerome



What I've noticed so far:

I had the qemu version 2.0.0 (kubuntu 14.04) and also obtained "PHY 
address is not setup Correctly 0" [1] at my call
!
! $make run/lwip
!
A manual qemu upgrade to version 2.6.0 [2] solves the problem with me. 
I can therefore confirm the solution note [3].


Furthermore, I have received warnings at my call
!
! $make run/lwip
!
by "ip4_addr.h" (within $ (Genode 
DIR)/contrib/lwip-136ee70f33ffced072262d589c24ab3252d15eff/include/lwip/lwip/).


I was able to resolve the warnings with me by a change in the line 200 
from origin:
!
! #define ip_addr_isany (addr1) ((addr1) == NULL || (addr1) -> addr == 
IPADDR_ANY)
!

to my solution:
!
! #define ip_addr_isany(addr1) ( (((void *) addr1) != NULL) ? 
((addr1)->addr == IPADDR_ANY) : 0 )
!


and a change due to lack of space in the line 213 from origin:
!
! LWIP_DEBUGF(debug, ("%"U16_F".%"U16_F".%"U16_F".%"U16_F,
!

to my solution:
!
! LWIP_DEBUGF(debug, ("%" U16_F ".%" U16_F ".%" U16_F ".%" U16_F,
!
