for various reasons (like making those more reliable).
Add a new flags bitmap to the TX control info and a new

In most cases, host that receives IPv4 and IPv6 multicast/broadcast
packets does not do anything with these packets. Therefore the
reception of these unwanted packets causes unnecessary processing
and power consumption.
Packet coalesce feature helps to reduce number of received
interrupts to host by buffering these packets in firmware/hardware
for some predefined time. Received interrupt will be generated when
one of the following events occur.
a) Expiration of hardware timer whose expiration time is set to
maximum coalescing delay of matching coalesce rule.
b) Coalescing buffer in hardware reaches it's limit.
c) Packet doesn't match any of the configured coalesce rules.
This patch adds set/get configuration support for packet coalesce.
User needs to configure following parameters for creating a coalesce
rule.
a) Maximum coalescing delay
b) List of packet patterns which needs to be matched
c) Condition for coalescence. pattern 'match' or 'no match'
Multiple such rules can be created.
This feature needs to be advertised during driver initialization.

Static routes in this case are non-expiring routes which did not get
configured by autoconf or by icmpv6 redirects.
To make sure we actually get an ecmp route while searching for the first
one in this fib6_node's leafs, also make sure it matches the ecmp route
assumptions.
v2:
a) Removed RTF_EXPIRE check in dst.from chain. The check of RTF_ADDRCONF
already ensures that this route, even if added again without
RTF_EXPIRES (in case of a RA announcement with infinite timeout),
does not cause the rt6i_nsiblings logic to go wrong if a later RA
updates the expiration time later.
v3:
a) Allow RTF_EXPIRES routes to enter the ecmp route set. We have to do so,
because an pmtu event could update the RTF_EXPIRES flag and we would
not count this route, if another route joins this set. We now filter
only for RTF_GATEWAY|RTF_ADDRCONF|RTF_DYNAMIC, which are flags that
don't get changed after rt6_info construction.

This change fixes an MTU sizing issue seen with gretap tunnels when non-gso
packets are sent from the interface.
In my case I was able to reproduce the issue by simply sending a ping of
1421 bytes with the gretap interface created on a device with a standard
1500 mtu.
This fix is based on the fact that the tunnel mtu is already adjusted by
dev->hard_header_len so it would make sense that any packets being compared
against that mtu should also be adjusted by hard_header_len and the tunnel
header instead of just the tunnel header.

In make_eligible, a mask is used to decide which groups must become eligible:
the i-th group becomes eligible only if the i-th bit of the mask (from the
right) is set. The mask is computed by left-shifting a 1 by a given number of
places, and decrementing the result. The shift is performed on a ULL to avoid
problems in case the number of places to shift is higher than 31. On a 32-bit
machine, this is more costly than working on an UL. This patch replaces such a
costly operation with two cheaper branches.
The trick is based on the following fact: in case of a shift of at least 32
places, the resulting mask has at least the 32 less significant bits set,
whereas the total number of groups is lower than 32. As a consequence, in this
case it is enough to just set the 32 less significant bits of the mask with a
cheaper ~0UL. In the other case, the shift can be safely performed on a UL.

This change makes it so that the GRE and VXLAN tunnels can make use of Tx
checksum offload support provided by some drivers via the hw_enc_features.
Without this fix enabling GSO means sacrificing Tx checksum offload and
this actually leads to a performance regression as shown below:
Utilization
Send
Throughput local GSO
10^6bits/s % S state
6276.51 8.39 enabled
7123.52 8.42 disabled
To resolve this it was necessary to address two items. First
netif_skb_features needed to be updated so that it would correctly handle
the Trans Ether Bridging protocol without impacting the need to check for
Q-in-Q tagging. To do this it was necessary to update harmonize_features
so that it used skb_network_protocol instead of just using the outer
protocol.
Second it was necessary to update the GRE and UDP tunnel segmentation
offloads so that they would reset the encapsulation bit and inner header
offsets after the offload was complete.
As a result of this change I have seen the following results on a interface
with Tx checksum enabled for encapsulated frames:
Utilization
Send
Throughput local GSO
10^6bits/s % S state
7123.52 8.42 disabled
8321.75 5.43 enabled
v2: Instead of replacing refrence to skb->protocol with
skb_network_protocol just replace the protocol reference in

("ipv6: rt6_check_neigh should successfully verify neigh if no NUD

Since the removal of rt->n in rt6_info we can end up with a dst ==
NULL in rt6_check_neigh. In case the kernel is not compiled with
CONFIG_IPV6_ROUTER_PREF we should also select a route with unkown
NUD state but we must not avoid doing round robin selection on routes
with the same target. So introduce and pass down a boolean ``do_rr'' to
indicate when we should update rt->rr_ptr. As soon as no route is valid
we do backtracking and do a lookup on a higher level in the fib trie.
v2:
a) Improved rt6_check_neigh logic (no need to create neighbour there)
and documented return values.

(thanks to David Miller).

Pull second round of 9p patches from Eric Van Hensbergen:
"Several of these patches were rebased in order to correct style
issues. Only stylistic changes were made versus the patches which
were in linux-next for two weeks. The rebases have been in linux-next
for 3 days and have passed my regressions.
The bulk of these are RDMA fixes and improvements. There's also some
additions on the extended attributes front to support some additional
namespaces and a new option for TCP to force allocation of mount
requests from a priviledged port"

Pull nfsd changes from Bruce Fields:
"Changes this time include:
- 4.1 enabled on the server by default: the last 4.1-specific issues
I know of are fixed, so we're not going to find the rest of the
bugs without more exposure.
- Experimental support for NFSv4.2 MAC Labeling (to allow running
selinux over NFS), from Dave Quigley.
- Fixes for some delicate cache/upcall races that could cause rare
server hangs; thanks to Neil Brown and Bodo Stroesser for extreme
debugging persistence.
- Fixes for some bugs found at the recent NFS bakeathon, mostly v4
and v4.1-specific, but also a generic bug handling fragmented rpc
calls"
