neigh: Keep neighbour cache entries if number of them is small enough.
Since we have removed NCE (Neighbour Cache Entry) reference from
routing entries, the only refcnt holders of an NCE are its timer
(if running) and its owner table, in usual cases. As a result,
neigh_periodic_work() purges NCEs over and over again even for
gateways.
It does not make sense to purge entries, if number of them is
very small, so keep them. The minimum number of entries to keep
is specified by gc_thresh1.

This patch add the support of proxy multicast, ie being able to build a static

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.

Rather than add a "YES YES YES" line for all of the drivers we

Furthermore, once established, we never fall back from one of the port

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

====================
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:

ixgbe: Update ixgbe Tx flags to improve code efficiency
This change is meant to improve the efficiency of the Tx flags in ixgbe by
aligning them with the values that will later be written into either the

functions to either just a simple shift followed by an or in the case of
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.

net: fec: enable pause frame to improve rx prefomance for 1G network
The limition of imx6 internal bus cause fec can't achieve 1G perfomance.
There will be many packages lost because FIFO over run.
This patch enable pause frame flow control.

ASIX AX88772B started to pack data even more tightly. Packets and the ASIX packet
header may now cross URB boundaries. To handle this we have to introduce
some state between individual calls to asix_rx_fixup().

====================
This series contains updates to e1000e and igb. Most notably is the
added timestamp support in e1000e and additional software timestamp
support in igb. As well as, the added thermal data support and SR-IOV
configuration support in igb.
v2- dropped the following patches from the previous 14 patch series
because changes were requested from the community:
e1000e: add support for IEEE-1588 PTP

igb: Free any held skb that should have been timestamped on remove
To prevent a race condition where an skb has been saved to return the Tx
timestamp later and the driver is removed, add a check to determine if we
have an skb stored and, if so, free it.

igb: Add mechanism for detecting latched hardware Rx timestamp
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
print a warning message to the syslog.
