Subject[PATCH 0/2] Make ipmr queue length configurable
Date
We want to have some more space in our queue for processing incoming
multicast packets, so we can process more of them without dropping
them prematurely. It is useful to be able to increase this limit on
higher-spec platforms that can handle more items.

For the particular use case here at Allied Telesis, we have linux
running on our switches and routers, with support for the number of
multicast groups being increased. Basically, this queue length affects
the time taken to fully learn all of the multicast streams.

Changes in v2:
- Tidy up a few unnecessary bits of code.
- Put the sysctl inside ip multicast ifdef.
- Included the IPv6 version.
