Herbert Xu	eb1d164143	bridge: Add core IGMP snooping support This patch adds the core functionality of IGMP snooping support without actually hooking it up. So this patch should be a no-op as far as the bridge's external behaviour is concerned. All the new code and data is controlled by the Kconfig option BRIDGE_IGMP_SNOOPING. A run-time toggle is also available. The multicast switching is done using an hash table that is lockless on the read-side through RCU. On the write-side the new multicast_lock is used for all operations. The hash table supports dynamic growth/rehashing. The hash table will be rehashed if any chain length exceeds a preset limit. If rehashing does not reduce the maximum chain length then snooping will be disabled. These features may be added in future (in no particular order): * IGMPv3 source support * Non-querier router detection * IPv6 Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

bridge: Add core IGMP snooping support

This patch adds the core functionality of IGMP snooping support
without actually hooking it up.  So this patch should be a no-op
as far as the bridge's external behaviour is concerned.

All the new code and data is controlled by the Kconfig option
BRIDGE_IGMP_SNOOPING.  A run-time toggle is also available.

The multicast switching is done using an hash table that is
lockless on the read-side through RCU.  On the write-side the
new multicast_lock is used for all operations.  The hash table
supports dynamic growth/rehashing.

The hash table will be rehashed if any chain length exceeds a
preset limit.  If rehashing does not reduce the maximum chain
length then snooping will be disabled.

These features may be added in future (in no particular order):

* IGMPv3 source support
* Non-querier router detection
* IPv6

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
