[BRIDGE]: keep track of received multicast packets

2006-05-06T00:07:13+00:00

It makes sense to add this simple statistic to keep track of received
multicast packets.

[BRIDGE]: receive link-local on disabled ports.

2006-04-12T00:21:05+00:00

This change allows link local packets (like 802.3ad and Spanning Tree
Protocol) to be processed even when the bridge is not using the port.
It fixes the chicken-egg problem for bridging a bonded device, and
may also fix problems with spanning tree failover.

[BRIDGE]: allow show/store of group multicast address

2006-03-21T06:59:21+00:00

Bridge's communicate with each other using Spanning Tree Protocol
over a standard multicast address. There are times when testing or
layering bridges over existing topologies or tunnels, when it is
useful to use alternative multicast addresses for STP packets.

The 802.1d standard has some unused addresses, that can be used for this.
This patch is restrictive in that it only allows one of the possible
addresses in the standard.

[BRIDGE]: use llc for receiving STP packets

2006-03-21T06:59:06+00:00

Use LLC for the receive path of Spanning Tree Protocol packets.
This allows link local multicast packets to be received by
other protocols (if they care), and uses the existing LLC
code to get STP packets back into bridge code.

The bridge multicast address is also checked, so bridges using
other link local multicast addresses are ignored. This allows
for use of different multicast addresses to define separate STP
domains.

[BRIDGE]: optimize frame pass up

2006-03-21T06:57:18+00:00

The netfilter hook that is used to receive frames doesn't need to be a
stub.  It is only called in two ways, both of which ignore the return
value.

[BRIDGE]: fix for RCU and deadlock on device removal

2006-02-10T01:08:52+00:00

Change Bridge receive path to correctly handle RCU removal of device
from bridge.  Also fixes deadlock between carrier_check and del_nbp.
This replaces the previous deleted flag fix.

[NET]: Use newer is_multicast_ether_addr() in some files

2006-01-06T21:05:58+00:00

This uses is_multicast_ether_addr() because it has recently been
changed to do the same thing these seperate tests are doing.

[BRIDGE]: filter packets in learning state

2006-01-03T21:11:02+00:00

While in the learning state, run filters but drop the result.
This prevents us from acquiring bad fdb entries in learning state.
