mac80211: simplify key locking
removed the synchronization against RCU and thus
opened a race window where we can use a key for
TX while it is already freed. Put a synchronisation
into the right place to close that window.

Commit b51aff057c said:
Under memory pressure, the mac80211 mesh code
may helpfully print a message that it failed
to clone a mesh frame and then will proceed
to crash trying to use it anyway. Fix that.
Avoid the reference whenever the frame copy is unsuccessful
regardless of the debug message being suppressed or printed.

Since commit 6cd0b1cb87 "iwlagn: fix
hw-rfkill while the interface is down", we enable interrupts when
device is not ready to receive them. However hardware, when it is in
some inconsistent state, can generate other than rfkill interrupts
and crash the system. I can reproduce crash with "kernel BUG at
drivers/net/wireless/iwlwifi/iwl-agn.c:1010!" message, when forcing
firmware restarts.
To fix only enable rfkill interrupt when down device and after probe.
I checked patch on laptop with 5100 device, rfkill change is still
passed to user space when device is down.

The binary file of the firmware is moved to linux-firmware repository.
The firmwares are rtl_nic/rtl8168d-1.fw and rtl_nic/rtl8168d-2.fw.
The driver goes along if the firmware couldn't be found. However, it
is suggested to be done with the suitable firmware.
Some wrong PHY parameters are directly corrected in the driver.
Simple firmware checking added per Ben Hutchings suggestion.

Yes, why not, I am only wondering why loopback / dummy (and others ?)
only set NETIF_F_TSO :)
Since I want to play with ECN, I might also add NETIF_F_TSO_ECN ;)
For other flags, I really doubt it can matter on ifb ?
[PATCH v3 net-next-2.6] ifb: add performance flags
IFB can use the full set of features flags (NETIF_F_SG |
NETIF_F_FRAGLIST | NETIF_F_TSO | NETIF_F_NO_CSUM | NETIF_F_HIGHDMA) to
avoid unnecessary split of some packets (GRO for example)
Changli suggested to also set vlan_features, NETIF_F_TSO6,
NETIF_F_TSO_ECN.
Jarek suggested to add NETIF_F_HW_VLAN_TX as well.

With the original 8 bit ISA ne1000 card being over 20 years old, it
only makes sense to consider ne.c and all the other toplevel 8390
based driver files as legacy for obsolete hardware. The most
recent thing made in large quantities that was 8390 based were
those crazy PCI ne2k clones - and even they are now 10+ years old.
Also remove myself as maintainer, since the only changes to these

Commit 3f5a2a713a zeroes out the statistics
message block (SMB) and coalescing message block (CMB) when adapter ring
resources are freed. This is desirable behavior, but, as a side effect,
the commit leads to an oops when atl1_set_ringparam() attempts to alter
the number of rx or tx elements in the ring buffer (by using ethtool
-G, for example). We don't want SMB or CMB to change during this
operation.
Modify atl1_set_ringparam() to preserve SMB and CMB when changing ring
parameters.

This implements 64 bit statistics support and fixes races when reading
counter values. The PHY counters can only be accessed 16 bits at a time,
so they are subject to carry races.
NB:
* TX/RX counters are maintained in software because the the hardware packet count
is only a 32 bit value.
* Error counters are really only 32 bit.
* Old 32 bit counter fields in dev->stats still used for some
software counters

Completes the simplification of TIPC's debugging capabilities. By default
TIPC includes no debugging code, and any debugging code added by developers
that calls the dbg() and dbg_macros() is compiled out. If debugging support
is enabled, TIPC prints out some additional data about its internal state
when certain abnormal conditions occur, and any developer-added calls to the
TIPC debug macros are compiled in.
