Subject: [PATCH iproute2-next 07/10] bridge: fdb: add flush [no]added_by_user entry matching
Date: Wed, 8 Jun 2022 15:29:18 +0300 [thread overview]
Message-ID: <20220608122921.3962382-8-razor@blackwall.org> (raw)
In-Reply-To: <20220608122921.3962382-1-razor@blackwall.org>
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.
