Date: Thu, 05 Nov 2015 13:37:41 -0500 (EST) From: David Miller <davem@...emloft.net> To: vivien.didelot@...oirfairelinux.com Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, kernel@...oirfairelinux.com, f.fainelli@...il.com, andrew@...n.ch Subject: Re: [PATCH net] net: dsa: mv88e6xxx: isolate unbridged ports From: Vivien Didelot <vivien.didelot@...oirfairelinux.com> Date: Wed, 4 Nov 2015 17:23:40 -0500 > The DSA documentation specifies that each port must be capable of > forwarding frames to the CPU port. The last changes on bridging support > for the mv88e6xxx driver broke this requirement for non-bridged ports. > > So as for the bridged ports, reserve a few VLANs (4000+) in the switch > to isolate ports that have not been bridged yet. > > By default, a port will be isolated with the CPU and DSA ports. When the > port joins a bridge, it will leave its reserved port. When it is removed > from a bridge, it will join its reserved VLAN again. > > Fixes: 5fe7f68016ff ("net: dsa: mv88e6xxx: fix hardware bridging") > Reported-by: Andrew Lunn <andrew@...n.ch> > Signed-off-by: Vivien Didelot <vivien.didelot@...oirfairelinux.com> Applied, thanks Vivien. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
