b7c6ba6eb1 [NETNS]: Consolidate kernel netlink socket destruction.
Create a specific helper for netlink kernel socket disposal. This just
let the code look better and provides a ground for proper disposal
inside a namespace.

4f84d82f7a [NETNS]: Memory leak on network namespace stop.
Network namespace allocates 2 kernel netlink sockets, fibnl &
rtnl. These sockets should be disposed properly, i.e. by
sock_release. Plain sock_put is not enough.

869e58f870 [NETNS]: Double free in netlink_release.
Netlink protocol table is global for all namespaces. Some netlink
protocols have been virtualized, i.e. they have per/namespace netlink
socket. This difference can easily lead to double free if more than 1
namespace is started. Count the number of kernel netlink sockets to
track that this table is not used any more.

7d460db953 [IPV6]: Fix ip6_frag ctl
Alexey Dobriyan reported an oops when unsharing the network
indefinitely inside a loop. This is because the ip6_frag is not per
namespace while the ctls are.

That happens at the fragment timer expiration:
inet_frag_secret_rebuild function is called and this one restarts the
timer using the value stored inside the sysctl field.

        "mod_timer(&f->secret_timer, now + f->ctl->secret_interval);"

When the network is unshared, ip6_frag.ctl is initialized with the new
sysctl instances, but ip6_frag has only one instance. A race in this
case will appear because f->ctl can be modified during the read access
in the timer callback.

Until the ip6_frag is not per namespace, I discard the assignation to
the ctl field of ip6_frags in ip6_frag_sysctl_init when the network
namespace is not the init net.

ee63d22b89 net: NEWEMAC: Fix problem with mtu > 4080 on non TAH equipped 4xx PPC's
Currently, all non TAH equipped 4xx PPC's call emac_start_xmit() upon
xmit. This routine doesn't check if the frame length exceeds the max.
MAL buffer size.

This patch now changes the driver to call emac_start_xmit_sg() on all
GigE platforms and not only the TAH equipped ones (440GX). This enables
an MTU of 9000 instead 4080.

f15ebb63b3 libertas: change inference about buffer size in lbs_cmd()
sizeof(*cmd) is going to give the total size of the data structure that
we allocated, more often than not. But the size of the command to be
_sent_ could be a lot smaller, as it is in the KEY_MATERIAL and
SUBSCRIBE_EVENT commands for example. So swap them round; let the caller
set the _command_ size explicitly in the header, and infer the
maximum response size from the data structure.

354eca9820 libertas: submit RSSI command on tx timeout, to check whether module is dead
We don't necessarily want to reset the device on a TX timeout. But more
often than not, the real cause is that the firmware has crapped itself,
not just that the network is busy. So submit any harmless command, and
if _that_ times out, then the error handling code will reset the module,
as appropriate.

24dba5f391 libertas: don't clear priv->dnld_sent after sending sleep confirm
DNLD_RES_RECEIVED is a bit of a misnomer -- we never wait for the result
to be received; it's purely representing the state of the TX path, and
in this case the TX path is definitely busy.

Of course, that means that we don't actually care about DATA_SENT vs.
CMD_SENT either, but that's a can of worms for another day...

38bfab1a01 libertas: fix buffer handling of PS_MODE commands and responses
Commit 5b8845345e7385d2eb37fac22ba9ab6905988be5 (or, in case the git
workflow is broken and patches get recommitted, the commit entitled
'libertas: rename and re-type bufvirtualaddr to cmdbuf' by dcbw),
introduced a number of bugs where we once had a pointer to a command
_payload_, but now we use the pointer to the command header instead.

The fix isn't wonderfully pretty for now, but it'll get better when we
finish converting all commands so the structures include the header.
