Hello All,
Summary:
===
If a userspace program has a well crafted packet (ethernet or IPv4 or

ingress'ed on that interface? Is this possible?
Detailed Problem D
Hi Rami,
Sorry for the delay in response.
In the buggy code, the missing lines were the following:
115 data->rta_len = (void *)NLMSG_TAIL(&req.n) - (void *)data;
116 linkinfo->rta_len = (void *)NLMSG_TAIL(&req.n) - (void *)linkinfo;
Above code is to adjust the length for nested attribut
this.

Hello,
I want to check with the group if this is right mailing list to post
my question.
Here is what I am doing.
+ From a user-space program, mimicking the behavior of creating a VLAN
interface when we execute the following ip command:
$ ip link add name link type
vlan id
Example: $ ip
