From: Somnath Kotur <redacted> The Lancer FW has a bug due to which in some cases vlan-promisc setting is cleared eventhough the vlan-list programming did not succeed (via VLAN_CONFIG) cmd. The driver has no way of knowing if the vlan-promisc mode was cleared or not when this cmd fails. To work around this issue, this patch first explicitly clears the vlan-promisc mode via RX_FILTER cmd and then tries to program the vlan list.
