The goal of this serie is to add the support of proxy multicast, ie being able
to build a static multicast tree. In other words, it adds the support of (*,G)
mf[6]c entries.

This patch add the support of proxy multicast, ie being able to build a static
multicast tree. It adds the support of (*,*) and (*,G) entries.
The user should define an (*,*) entry which is not used for real forwarding.
This entry defines the upstream in iif and contains all interfaces from the
static tree in its oifs. It will be used to forward packet upstream when they
come from an interface belonging to the static tree.
Hence, the user should define (*,G) entries to build its static tree. Note that
upstream interface must be part of oifs: packets are sent to all oifs
interfaces except the input interface. This ensures to always join the whole
static tree, even if the packet is not coming from the upstream interface.

The original intent of this file was to list limitations in
drivers/hardware relating to multicast use, back when some
modest hardware from the early 1990s did not support things
we might take for granted today.
I was intending to delete some now-gone MCA/token ring entries
in this file, but once I opened it, I found it only contained
information on the earliest (pre-2000) linux networking drivers.
Checking the git history shows that the file hasn't been touched
since 2005. Clearly nobody is actively consulting this file
as a meaningful reference.
Rather than add a "YES YES YES" line for all of the drivers we
currently have, lets just take advantage of the fact that nobody
is using the file to delete it.
This has the side benefit of not having to do a line-by-line
deletion of the file content as each older driver is expired.

Commit 46d3ceab "tcp: TCP Small Queues" has severly degraded
performance for single connection RR workloads on HiperSockets with
MTU >=16K due to a conflict of the TCP Small Queues approach with our
buffer scan threshold which releases buffers not frequently enough yet.
This fix restores performance to the same level as before cited commit.

The existing port isolation mode 'forward' will now verify that the adjacent
switch port supports the required reflective relay (RR) mode. This patch adds
the required error handling for the cases where enabling port isolation mode
'forward' can now fail.
Furthermore, once established, we never fall back from one of the port
isolation modes to a non-isolated mode without further user-interaction.
This includes cases where the isolation mode was enabled successfully, but
ceases to work e.g. due to configuration changes at the switch port.
Finally, configuring an isolation mode with the device being offline
will make onlining the device fail permanently upon errors encountered until
either errors are resolved or the isolation mode is changed by the user to a
different mode.

====================
This series of changes basically clean up NDISC logic,
especially on sender side.
We originally do For NS/NA/RS:
1) build temporary ICMPv6 header
2) ndisc_build_skb() with temporary ICMPv6 header and rather
criptic arguments.
- Calculate total length and allocate sk_buff
- Build IPv6 header.
- copy ICMPv6 header, additional data and ND options.
- Fill-in ICMPv6 checksum.
Here, structures defined for message format was not used
at all, it is difficult to understand what is being sent,
and it was not generic.
3) __ndisc_send()
- Allocate temporary dst.
- Send it.
Several issues:
- We could not defer decision if we should/can send some ND
option.
- It is hard to see the packet format at a glance.
- ICMPv6 header was built as temporary variable, and then
copied to the buffer.
- Some code path for Redirect was not shared.
With these patches, we do:
1) Calculate (or estimate) message length and option length.
2) Allocate skb (via new ndisc_skb_alloc()).
3) Fill-in ICMPv6 message directly using compound literals.
4) Fill-in ICMPv6 checksum
5) Build IPv6 header (including length)
6) Send the packet (via ndisc_send_skb()).
- allocate temporary dst and send it.
- We can defer calculating real length of the packet.
For example, we can give up filling some option at when
filling in.
- Message is built directly without temporary buffer.
- Structures defined for message format is easier to understand
what is being built.
- NS/NA/RS/Redirect share same logic.
- Reduced code/data size:
text data bss dec hex filename
265407 14133 3488 283028 45194 old/net/ipv6/ipv6.o

platforms with BPF JIT appears competitive with traditional

The size of the filter has been artificially limited to 64

using this new match.
