mcast: add multicast proxy support (IPv4 and IPv6)
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.

Documentation: remove obsolete networking/multicast.txt file
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.

46d3ceab "tcp: TCP Small Queues" has severly degraded

qeth: Support VEPA mode
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.

Merge branch 'ipv6_ndisc'
YOSHIFUJI Hideaki says:
====================
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:

cmd_type, or an and followed by an or in the case of olinfo.
To do this I also needed to change the logic and/or drop some flags. I
dropped the IXGBE_TX_FLAGS_FSO and it was replaced by IXGBE_TX_FLAGS_TSO since
the only place it was ever checked was in conjunction with IXGBE_TX_FLAGS_TSO.
I replaced IXGBE_TX_FLAGS_TXSW with IXGBE_TX_FLAGS_CC, this way we have a
clear point for what the flag is meant to do. Finally the
IXGBE_TX_FLAGS_NO_IFCS was dropped since were are already carrying the data
for that flag in the skb. Instead we can just check the bitflag in the skb.

net/davinci: do not use all descriptors for tx packets
The driver uses a shared pool for both rx and tx descriptors.
During open it queues fixed number of 128 descriptors for receive
packets. For each received packet it tries to queue another
descriptor. If this fails the descriptor is lost for rx.
The driver has no limitation on tx descriptors to use, so it
can happen during a nmap / ping -f attack that the driver
allocates all descriptors for tx and looses all rx descriptors.
The driver stops working then.
To fix this limit the number of tx descriptors used to half of
the descriptors available, the rx path uses the other half.
Tested on a custom board using nmap / ping -f to the board from
two different hosts.

Add a check against possible Rx timestamp freezing in the hardware via
watchdog mechanism. This situation can occur when an Rx timestamp has been
latched, but the packet has been dropped because the Rx ring is full.
Whenever a packet comes in that should be timestamped, the Rx timestamp
gets latched into the hardware registers and we will store the jiffy value
in the rx_ring. The watchdog will keep track of his own jiffy timer
whenever there is no valid timestamp in the registers.
If the watchdog detects a valid timestamp in the registers, meaning that no
Rx packet has consumed it yet, it will check which time is most recent: the
last time in the watchdog or any time in the rx_rings. If the most recent
"event" was more than 5 seconds ago, it will flush the Rx timestamp and

e1000e: Use standard #defines for PCIe Capability ASPM fields
Use the standard #defines for PCIe Capability ASPM fields.
Previously we used PCIE_LINK_STATE_L0S and PCIE_LINK_STATE_L1 directly, but
these are defined for the Linux ASPM interfaces, e.g.,
pci_disable_link_state(), and only coincidentally match the actual register
bits. PCIE_LINK_STATE_CLKPM, also part of that interface, does not match
the register bit.

ipv6: Introduce rt6_nexthop() to select nexthop address.
For RTF_GATEWAY route, return rt->rt6i_gateway.
Otherwise, return 2nd argument (destination address).
This will be used by following patches which remove rt->n
dependency patches in ip6_dst_lookup_tail() and ip6_finish_output2().
