Questions on Netlink sockets

[Rami Rosen]

Hi, Bhaskar,

Indeed the netdev mailing list is too advanced for this.

Do you get any error as a result of sending this netlink message ?
(I mean error in userspace or in kernel; if there is an error message
in the kernel it can be viewed by looking at the end of dmesg output)

Further more, I suggest that you will post the code here. The concept
itself is right, It should work, you either build the netlink message
incorrectly or send it incorrectly, so it seems.

Regards,
