I made some incremental changes, can you take a look to see if they seem reasonable to you? Here are the main blocks: - Additional interface documentation. - Fix memory leak when installing a new flow if there is an allocation failure for the mask. - Require Ethernet addresses to be present in the key, as before. - Make SNAP handling a little more integrated with the rest of the parsing and validation code. - Make ovs_flow_free() and ovs_deferred_flow_free() have exactly the same behavior, just with the addition of RCU, to avoid possible confusion. - Return errors directly rather than through an intermediate variable in ovs_flow_extract() and children. - Enforce an exact match for the outer EtherType for vlan packets, similar to what we do for other protocols. - Miscellaneous style fixes.
