Date: Mon, 11 Jul 2022 08:07:52 -0400 From: Jonathan Toppins <jtoppins@...hat.com> To: netdev@...r.kernel.org Cc: jtoppins@...hat.com, razor@...ckwall.org, "David S. Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com>, linux-kernel@...r.kernel.org Subject: [RESEND PATCH iproute2 next v4] bond: add mac_filter option Add ability to set bonding option `mac_filter`. Values greater than zero represent the maximum hashtable size the mac filter is allowed to grow to, zero disables the filter.
