Do the work of parsing NDA_VLAN directly in rtnetlink code, pass simple

I know this maintains status quo of what is already in the kernel.
But we need to take care of policy (pass it from user space) which
dictates how to proceed on failure. Three possible options:
1) If something fails just continue with the rest of the transaction.
Return success if at least one thing succeeds.
2) If something fails stop transaction and return some partial success code
3) If something fails undo everything that has been done and return failure.

So two bits from somewhere would be useful to send from userspace->kernel

+static int fbd_vid_parse(struct nlattr *vlan_attr, u16 *p_vid)

typo fbd_vid_parse -> fdb_vid_parse
