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.
