Add flush support to match entries with or without (if "no" is prepended) added_by_user flag. Note that NTF_USE is used internally because there is no NTF_ flag that describes such entries. Examples: $ bridge fdb flush dev br0 added_by_user This will delete all added_by_user entries in br0's fdb table. $ bridge fdb flush dev br0 noadded_by_user This will delete all entries except the ones with added_by_user flag in br0's fdb table.
