Feature lists for `firewall` providers were out of date, and
`physdev_in` and `physdev_out` were listed as features instead of
parameters.

 * `outiface`: Output interface to filter on. Values must match '/^!?\s?[a-zA-Z0-9\-\._\+\:]+$/'.  Requires the `interface_match` feature.  Supports interface alias (eth0:0) and negation.
 
+* `physdev_in`: Match if the packet is entering a bridge from the given interface. Values must match '/^[a-zA-Z0-9\-\._\+]+$/'.
+
+* `physdev_out`: Match if the packet is leaving a bridge via the given interface. Values must match '/^[a-zA-Z0-9\-\._\+]+$/'.
+
 * `pkttype`: Sets the packet type to match. Valid values are: 'unicast', 'broadcast', and'multicast'. Requires the `pkttype` feature.
 
 * `port`: The destination or source port to match for this filter (if the protocol supports ports). Will accept a single element or an array. For some firewall providers you can pass a range of ports in the format: 'start number-end number'. For example, '1-1024' would cover ports 1 to 1024.
