From: Xi Wang <wangxi11@huawei.com>
According to the functional specification of hardward, the first descriptor of response from command 'lookup vlan talbe' is not valid. Currently, the first descriptor is parsed as normal value, which will cause an expected error.
This patch fixes this problem by skipping the first descriptor.
