11 * *_REQUEST states are used to mark filter to be sent to PF driver to perform
12 * an action (either add or delete filter). *_PENDING states are an indication
13 * that request was sent to PF and the driver is waiting for response.
14 *
15 * Both DELETE and DISABLE states are being used to delete a filter in PF.
16 * The difference is that after a successful response filter in DEL_PENDING
17 * state is being deleted from VF driver as well and filter in DIS_PENDING state
18 * is being changed to INACTIVE state.
