bridge: fdb: add flush [no]dynamic entry matching
Add flush support to match dynamic or non-dynamic (static or permanent) entries if "no" is prepended respectively. Note that dynamic entries are defined as fdbs without NUD_NOARP and NUD_PERMANENT set, and non-dynamic entries are fdbs with NUD_NOARP set (that matches both static and permanent entries). Examples: $ bridge fdb flush dev br0 dynamic This will delete all dynamic entries in br0's fdb table. $ bridge fdb flush dev br0 nodynamic This will delete all entries except the dynamic ones in br0's fdb table.
