RTEMS 5.1 Release LibBSD Networking Issue

[rvanderwal]

Good Morning,
I seem to be having an issue with RTEMS 5.1 Release Libbsd networking when I include my own 'rtems_bsd_get_mac_address' function as described in rtemsbsd/include/rtems/bsd/bsd.h. I'm running on a Xilinx Microzed using xilinx_zynq_zedboard BSP and have a minimal RTEMS console application (source code included below). The rc.conf file configures the cgem0 interface and starts FTP and telnet daemons.
If I include the 'rtems_bsd_get_mac_address' function, the mac address is set but RTEMS doesn't respond to any pings and doesn't allow any connections. However, a ping to an external device from RTEMS is successful. I have run tcpdump filtering on ICMP messages and RTEMS sees them.
If I comment out the 'rtems_bsd_get_mac_address' function, it has the default mac address and everything works as expected.
All guidance and help are greatly appreciated.
Thanks,Rick
