My code fragment is below:<br><br>"<i>nl_sk = netlink_kernel_create(16, 0, nl_data_ready, THIS_MODULE);"</i> <br><br>It can be "make" and "insmod" correctly. But error mesage is printed into log. It indicates the netlink_kernel_create() returns NULL.<br>
<br>Once I change the firt parameter to another(<32 && >16), system crash when I execute insmod.<br><br>Is the protocol ID occupied? Why can't use another and how to define a new ID? I have tried to update net_link.h but fail also.<br>
