macvtap: signal truncated packets
[ Upstream commit ce232ce01d61b184202bb185103d119820e1260c ]
macvtap_put_user() never return a value grater than iov length, this in fact
bypasses the truncated checking in macvtap_recvmsg(). Fix this by always
returning the size of packet plus the possible vlan header to let the trunca
checking work.
