IEEE 1588 ptp daemon with LWIP

I have ported the IEEE 1588 ptpd code from sourceforge to a BF537 lwip project using VisualDSP++5 update 8.

It works great. However, after I upgraded to VisualDSP update 10, it does no longer update time. Looks like it stops getting multicast messages immediately after startup. This ptpd project also works fine with update 9.1. I noticed Update 10 uses a newer version of LWIP (1.4.0). Previous version of LWIP was 1.3.2. Is there anything different in these versions of LWIP that may cause ptp network traffic to halt ?
