[NETNS][IPV6] Move sysctl initialization later on in the IPv6 init sequence
This patch moves initialization of IPv6 sysctl stuff at the end of
IPv6 initialization.
This will be helpful for network namespaces where some sysctl entries
depend on per-namespace variables, that need to be allocated and
initialized before they are referenced by sysctl.

[TCP]: TCP cubic v2.2
We have updated CUBIC to fix some issues with slow increase in large
BDP networks. We also improved its convergence speed. The fix is in
fact very simple -- the window increase limit of smax during the
window probing phase (i.e., convex growth phase) is removed. We found
that this does not affect TCP friendliness, but only improves its
scalability. We have run some tests in our lab and also over the
Internet path from NCSU to Japan. These results can be seen from the

init_net, but we should be able to have a timer per namespace and use
the timer callback parameter to pass the network namespace from the

The timer callback, fib6_run_gc, is actually used to be called
synchronously by some functions and asynchronously when the timer
expires.
When the timer expires, the delay specified for fib6_run_gc parameter
is always zero. So, I changed fib6_run_gc to not be a timer callback
but a function called by the timer callback and I added a timer
callback where its work is just to retrieve from the data arg of the

mac80211: split ieee80211_key_alloc/free
In order to RCU-ify sta_info, we need to be able to allocate
a key without linking it to an sdata/sta structure (because
allocation cannot be done in an rcu critical section). This
patch splits up ieee80211_key_alloc() and updates all users
appropriately.
While at it, this patch fixes a number of race conditions
such as finally making key replacement atomic, unfortunately
at the expense of more complex code.
Note that this patch documents /existing/ bugs with sta info
and key interaction, there is currently a race condition
when a sta info is freed without holding the RTNL. This will
finally be fixed by a followup patch.

rt2x00: correct address calc for queue private data
When calculating the offset to add to the queue entry base to get the
individual entry's private data area the base address must be treated
as a char * not a struct queue_entry so we can do byte oriented
pointer arithmetic with it.

rt2x00: Make rt2x00 less verbose
Remove the debug messages regarding initialization from
EEPROM. The values are vendor specific, and are not really
needed for debug purposes. If they ever become usefull we
still have access to them through debugfs which also
prints the exact same values...

rt2x00: Fix invalid DMA free
Be more strict when using the queue_entry_priv_pci_rx
and queue_entry_priv_pci_tx structures. Only use a
particular type that matches the queue type.
When freeing the DMA the priv_tx->data and priv_tx->dma
was used. This is incorrect since the start of the DMA
was in fact the priv_tx->desc pointer. Instead of
recalculating the dma_addr_t for the DMA start this
patch will swap the data and descriptor part of the
allocated memory.

wireless: rt2x00: fix driver menu indenting
Michael Büker <m.bueker@berlin.de> reports that the RT2x00 drivers
are not indented as they should be, so use proper dependencies to make
them be indented as expected.
