Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.PTP Packets are send from a user space application to a TAP interface.
2.Packet Rx count is incremented at TAP interface.
3. Now when the PTPv2 stack is bound to "tap0" using "-b" the packets are not 
received at the PTPv2 stack.

What is the expected output? What do you see instead?
Packets are exoected to be recived from teh TAP0 interface.

What version of the product are you using? On what operating system?
I am using Linux.

Please provide any additional information below.
The same with eth0 interface works fine.

The problem is fixed in case the
setsockopt(rawSock,SOL_SOCKET,SO_BINDTODEVICE,&ifs[tapIdx],sizeof(struct ifreq))
is used.
