[ Upstream commit 6c39d5278e62956238a681e4cfc69fae5507fc57 ]
According to the functional specification of hardware, 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.
