First of all thanks for your help.

Now I have set up this driver and compiled it with PTP support but there is nothing different than before still 

ptp4l[98.033]: port 1: get_ts_info not supported
ptp4l[98.035]: port 1: INITIALIZING to LISTENING on INITIALIZE
ptp4l[98.035]: port 0: INITIALIZING to LISTENING on INITIALIZE
ptp4l[104.035]: port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES
ptp4l[105.041]: recvmsg tx timestamp failed: Resource temporarily unavailable
ptp4l[105.041]: port 1: send sync failed
ptp4l[105.041]: port 1: MASTER to FAULTY on FAULT_DETECTED
ptp4l[121.043]: port 1: FAULTY to LISTENING on FAULT_CLEARED
ptp4l[127.043]: port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES
ptp4l[128.049]: recvmsg tx timestamp failed: Resource temporarily unavailable

As you can see below that the new driver is working:

~$ ethtool -i eth2
driver: e1000e
version: 2.3.2-NAPI
firmware-version: 2.1-2
bus-info: 0000:07:00.0

changing the kernel to 3.5 or 3.9 would take a lot of time because a lot of realtime support is bound into it. So I would prefer staying on 3.2. 

Is there something I still can try?

Thanks, 
Benny
