Fix for a -Warray-bounds warning. mixer_notify_update() tries to
write to ((CAPI_MSG *) msg)->info.facility_req.structs[3] while
structs is defined as byte structs[1]. Set all 'structs' which are
part of the typdefs in the info union to 'byte structs[0]'.
v2: set all info.*.structs to byte structs[0]

We've moving to a model where dst_entry objects to not have
a reference to the associated neighbour entry, instead such
neighbours must be looked up on-demand.
Here in qeth_l3_fill_header() it's actually much simpler to
use the information in the route itself. The code is
already conditionalized upon protocol type.

The X520 family of network devices, with the 82599 chip, support a
small number of Intel-verified SFP+ modules on their NICs. To maintain
stability and quality, the current devices restrict untested 3rd party
SFP+ modules.
This patch introduces a module parameter for ixgbe to allow these untested
modules at the user's peril. It also includes a warning to the syslog
alerting users that the modules aren't supported, and results may
vary.

TCP RST mechanism is broken in TCP md5(RFC2385). When
connection is gone, md5 key is lost, sending RST
without md5 hash is deem to ignored by peer. This can
be a problem since RST help protocal like bgp to fast
recove from peer crash.
In most case, users of tcp md5, such as bgp and ldp,
have listener on both sides to accept connection from peer.
md5 keys for peers are saved in listening socket.
There are two cases in finding md5 key when connection is
lost:
1.Passive receive RST: The message is send to well known port,
tcp will associate it with listner. md5 key is gotten from
listener.
2.Active receive RST (no sock): The message is send to ative
side, there is no socket associated with the message. In this
case, finding listener from source port, then find md5 key from
listener.
we are not loosing sercuriy here:
packet is checked with md5 hash. No RST is generated
if md5 hash doesn't match or no md5 key can be found.

tcp_v4_send_reset() without holding socket lock (upcoming patch from

we can free socket without this grace period thanks to

There is no limit on number of MD5 keys an application can attach to a
tcp socket.
This patch adds a per tcp socket limit based
on /proc/sys/net/core/optmem_max

64bit arches, and 88 keys on 32bit arches.

In order to be able to support proper RST messages for TCP MD5 flows, we
need to allow access to MD5 keys without locking listener socket.
This conversion is a nice cleanup, and shrinks size of timewait sockets
by 80 bytes.

Add ability to return neighbour proxies list to caller if
it sent full ndmsg structure and has NTF_PROXY flag set.
Before this patch (and before iproute2 patches):
$ ip neigh add proxy 2001::1 dev eth0
$ ip -6 neigh show
$
After it and with applied iproute2 patches:
$ ip neigh add proxy 2001::1 dev eth0
$ ip -6 neigh show
2001::1 dev eth0 proxy
$
Compatibility with old versions of iproute2 is not broken,
kernel checks for incoming structure size and properly
works if old structure is came.
[v2]
* changed comments style.
* removed useless line with continue and curly bracket.
* changed incoming message size check from equal to more or
equal.

This function returns the page offset of the buffer, which can be
calculated based on either its DMA address or its virtual address. It
used to use the virtual address and we would cast that to unsigned
long, as anything smaller would result in a compiler warning. Now
that it's using the DMA address we should use unsigned int, matching
the return type. It is also unnecessary to use __force.

The irq handler was a mess.
See 7ab87ff4c770eed71e3777936299292739fcd0fe ("via-rhine: move work from
irq handler to softirq and beyond") for similar changes. One can notice:
- all non-napi tasks are explicitely scheduled trough a single work queue.
- hiding software tx queue start behind the rtl_hw_start method is mildly
natural. Move it in the caller where needed.
- as can be seen from the heavy use of bh disabling locks, the driver is
not safe for irq context messages with netconsole. It is still quite
usable for general messaging though. Tested ok with concurrent registers
dump (ethtool -d) + background traffic + "echo t > /proc/sysrq-trigger".
Tested with old PCI chipset, PCIe 8168 and 810x:
- XID 0c900800 RTL8168evl/8111evl
- XID 18000000 RTL8168b/8111b
- XID 98000000 RTL8169sc/8110sc
- XID 083000c0 RTL8168d/8111d
- XID 081000c0 RTL8168d/8111d
- XID 00b00000 RTL8105e
- XID 04a00000 RTL8102e
As a side note, the comments in f11a377b3f4e897d11f0e8d1fc688667e2f19708
("r8169: avoid losing MSI interrupts") does not seem completely clear: if
I hack the driver further to stop acking the irq link event bit, MSI
interrupts keep being delivered (RTL8168b/8111b, XID 18000000).

I see no good reason to keep both rtl8169_reinit_task and rtl8169_reset_task:
- rtl8169_reinit_task adds a software failure point which does relate to
any hardware state
- they handle hardware the same. Remember that rtl8169_reinit_task was
introduced in the 8169 only era to handle PCI errors way before the 8168
asked for pll and firmware ops and compare :
rtl8169_reinit_task | rtl8169_reset_task
----------------------------+--------------------------
rtl8169_wait_for_quiescence | rtl8169_hw_reset
rtl8169_update_counters | rtl8169_wait_for_quiescence

The generic lib.c file contains code relative to the various MACs, NVM and
Manageability supported by the driver. This patch splits the file into
three which are specific to those areas similar to how the PHY-specific
code is in phy.c and code specific to the 80003es2lan, 8257x, and ichX
MAC families are in their own files. The generic code that is applicable
to all MAC/PHY parts supported by the driver remains in netdev.c, param.c
and ethtool.c files. No change in functionality, just moving code
around for ease of maintenance, with some whitespace and other checkpatch
cleanups.
