listener can be source of false sharing. request sock has some
useful information like : ireq->ir_iif, ireq->ir_num, ireq->ireq_net
This patch does not solve the major problem of having to read
sk->sk_protocol which is sharing a cache line with sk->sk_wmem_alloc.
(This same field is read later in ip_build_and_send_pkt())
One idea would be to move sk_protocol close to sk_family
(using 8 bits instead of 16 for sk_family seems enough)

make it same as the netdev_switch_port_bridge_setlink/dellink
api (ie traverse lowerdevs to get to the switch port).
removes "WARN_ON(!ops->ndo_switch_parent_id_get)" because
direct bridge ports can be stacked netdevices (like bonds
and team of switch ports) which may not implement this ndo.
v2 to v3:
- remove changes to bond and team. Bring back the
transparently following lowerdevs like i initially
had for setlink/getlink
(http://www.spinics.net/lists/netdev/msg313436.html)
dave and scott feldman also seem to prefer it be that
way and move to non-transparent way of doing things
if we see a problem down the lane.
v3 to v4:
- fix ret initialization
v4 to v5:
- return err on first failure (scott feldman)
v5 to v6:
- change variable name (err) and initialize to
-EOPNOTSUPP (scott feldman).

skb->priority can be set for two purposes:
1) With respect to IP TOS field, which is computed by a mask.
Ususally used for priority qdisc's (pfifo, prio etc.), on TX
side (we only have ingress qdisc on RX side).
2) Used as a classid or flowid, works in the same way with tc
classid. What's more, this can even override the classid
of tc filters.
For case 1), it has been respected within its netns, I don't
see any point of keeping it for another netns, especially
when packets will be forwarded to Rx path (no matter from TX
path or RX path).
For case 2) we care, our applications run inside a netns,
and we classify the packets by our own filters outside,
If some application sets this priority, it could bypass
our filters, therefore clear it when moving out of a netns,
it makes no sense to bypass tc filters out of its netns.

The way the algif_skcipher works currently is that on sendmsg/sendpage it
builds an sgl for the input data and then on read/recvmsg it sends the job
for encryption putting the user to sleep till the data is processed.
This way it can only handle one job at a given time.
This patch changes it to be asynchronous by adding AIO support.

Firstly, handle zero length calls properly. Believe it or not there
are a few of these happening during early boot.
Next, we can't just drop to a memcpy() call in the forward copy case
where dst <= src. The reason is that the cache initializing stores
used in the Niagara memcpy() implementations can end up clearing out
cache lines before we've sourced their original contents completely.
For example, considering NG4memcpy, the main unrolled loop begins like
this:
load src + 0x00
load src + 0x08
load src + 0x10
load src + 0x18
load src + 0x20
store dst + 0x00
Assume dst is 64 byte aligned and let's say that dst is src - 8 for
this memcpy() call. That store at the end there is the one to the
first line in the cache line, thus clearing the whole line, which thus
clobbers "src + 0x28" before it even gets loaded.
To avoid this, just fall through to a simple copy only mildly
optimized for the case where src and dst are 8 byte aligned and the
length is a multiple of 8 as well. We could get fancy and call
GENmemcpy() but this is good enough for how this thing is actually
used.

When the device is powered up, some (older) firmware versions fail to work
properly if we send commands before the boot is complete (everything is OK
when the device is hot-plugged). The firmware indicates its ready status by
putting the link up.
Newer firmwares delay the first command so they don't suffer from this problem.
They also report the link being always up.
Wait for firmware to become ready (link up) before sending any commands and/or
data.
This also allows lowering CMD_TIMEOUT value to a reasonable time.
Tested with 4.1.0.9 (old) and 4.1.0.30 (new) firmware versions.

NetCP 1.5 available on newer K2 SoCs such as K2E and K2L introduced 3
variants of the ethss subsystem, 9 port, 5 port and 2 port. These have
one host port towards the CPU and N external slave ports.
To customize the driver for these new ethss sub systems, multiple
compatibility strings are introduced. Currently some of parameters that
are different on different variants such as number of ALE ports, stats
modules and number of ports are defined through constants. These are now
changed to variables in gbe_priv data that get set based on the
compatibility string. This is required as there are no hardware
identification registers available to distinguish among the variants
of NetCP 1.5 ethss. However there is identification register available
to differentiate between NetCP 1.4 vs NetCP 1.5 and the same is made use
of in the code to differentiate them.
For more reading on the details of this peripheral, please refer to the

Ethss has multiple modules within the sub system
- switch sub system
- sgmii
- mdio
- switch module
NetCP driver re-uses existing davinci mdio driver. It requires to
have its own register region to map the reg space. So restructure
the code to use separate reg region for the individual modules it
manages. Use range property to define register space of NetCP and
use reg property to define individual reg spaces. So MDIO will have
its own reg space to map. This is a pre-requisite to enable MDIO
driver for NetCP.

We send unicast neighbor (ARP or NDP) solicitations ucast_probes
times in PROBE state. Zhu Yanjun reported that some implementation
does not reply against them and the entry will become FAILED, which
is undesirable.
We had been dealt with such nodes by sending multicast probes mcast_
solicit times after unicast probes in PROBE state. In 2003, I made
a change not to send them to improve compatibility with IPv6 NDP.
Let's introduce per-protocol per-interface sysctl knob "mcast_
reprobe" to configure the number of multicast (re)solicitation for
reconfirmation in PROBE state. The default is 0, since we have
been doing so for 10+ years.

This work extends the "classic" BPF programmable tc action by extending
its scope also to native eBPF code!
Together with commit e2e9b6541dd4 ("cls_bpf: add initial eBPF support
for programmable classifiers") this adds the facility to implement fully
flexible classifier and actions for tc that can be implemented in a C
subset in user space, "safely" loaded into the kernel, and being run in
native speed when JITed.
Also, since eBPF maps can be shared between eBPF programs, it offers the
possibility that cls_bpf and act_bpf can share data 1) between themselves
and 2) between user space applications. That means that, f.e. customized
runtime statistics can be collected in user space, but also more importantly
classifier and action behaviour could be altered based on map input from
the user space application.
For the remaining details on the workflow and integration, see the cls_bpf
commit e2e9b6541dd4. Preliminary iproute2 part can be found under [1].

In order to prepare eBPF support for tc action, we need to add
sched_act_type, so that the eBPF verifier is aware of what helper
function act_bpf may use, that it can load skb data and read out
currently available skb fields.
This is bascially analogous to 96be4325f443 ("ebpf: add sched_cls_type
and map it to sk_filter's verifier ops").
BPF_PROG_TYPE_SCHED_CLS and BPF_PROG_TYPE_SCHED_ACT need to be
separate since both will have a different set of functionality in
future (classifier vs action), thus we won't run into ABI troubles
when the point in time comes to diverge functionality from the
classifier.
The future plan for act_bpf would be that it will be able to write
into skb->data and alter selected fields mirrored in struct __sk_buff.
For an initial support, it's sufficient to map it to sk_filter_ops.

If ->run() fails, it can either free the data structures it
allocated, or leave that task to ->free() which will be called
on failures.
However:
md.c calls ->free() even if ->private_data is NULL, which
causes problems in some personalities.
raid0.c frees the data, but doesn't clear ->private_data,
which will become a problem when we fix md.c
So better fix both these issues at once.
