Add a driver for BCM8706 and BCM8727 devices. These are a 10Gig PHYs
which use MII_ADDR_C45 addressing. They are always 10G full duplex, so
there is no autonegotiation. All we do is report link state and send
interrupts when it changes.
If the PHY has a device tree of_node associated with it, the
"broadcom,c45-reg-init" property is used to supply register
initialization values when config_init() is called.

Allow PHY drivers to supply their own device matching function
(match_phy_device()), or to be matched OF compatible properties.
PHYs following IEEE802.3 clause 45 have more than one device
identifier constants, which breaks the default device matching code.
Other 10G PHYs don't follow the standard manufacturer/device
identifier register layout standards, but they do use the standard
MDIO bus protocols for register access. Both of these require
adjustments to the PHY driver to device matching code.
If the there is an of_node associated with such a PHY, we can match it
to its driver using the "compatible" properties, just as we do with
certain platform devices. If the "compatible" property match fails,
first check if there is a driver supplied matching function, and if
not fall back to the existing identifier matching rules.

Define two new "compatible" values for Ethernet
PHYs. "ethernet-phy-ieee802.3-c22" and "ethernet-phy-ieee802.3-c45"
are used to indicate a PHY uses the corresponding protocol.
If a PHY is "compatible" with "ethernet-phy-ieee802.3-c45", we
indicate this so that get_phy_device() can properly probe the device.
If get_phy_device() fails, it was probably due to failing the probe of
the PHY identifier registers. Since we have the device tree telling
us the PHY exists, go ahead and add it anyhow with a phy_id of zero.
There may be a driver match based on the "compatible" property.

The IEEE802.3 clause 45 MDIO bus protocol allows for directly
addressing PHY registers using a 21 bit address, and is used by many
10G Ethernet PHYS. Already existing is the ability of MDIO bus
drivers to use clause 45, with the MII_ADDR_C45 flag. Here we add
struct phy_c45_device_ids to hold the device identifier registers
present in clause 45. struct phy_device gets a couple of new fields:
c45_ids to hold the identifiers and is_c45 to signal that it is clause
45.
get_phy_device() gets a new parameter is_c45 to indicate that the PHY
device should use the clause 45 protocol, and its callers are adjusted
to pass false. The follow-on patch to of_mdio.c will pass true where
appropriate.
EXPORT phy_device_create() so that the follow-on patch to of_mdio.c
can use it to create phy devices for PHYs, that have non-standard
device identifier registers, based on the device tree bindings.

We register with bnx2x before we allocate ctx_tbl structure, so it is
possible for bnx2x to call cnic_ctl before the structure is allocated.
This can sometimes cause NULL pointer dereference of cp->ctx_tbl. We
fix this by adding simple checking for valid state before proceeding.
The cnic_ctl call is RCU protected so we don't have to deal with race
conditions.
Because of the additional checking, we need to finish the shutdown

DDOS synflood attacks hit badly IP route cache.
On typical machines, this cache is allowed to hold up to 8 Millions dst
entries, 256 bytes for each, for a total of 2GB of memory.
rt_garbage_collect() triggers and tries to cleanup things.
Eventually route cache is disabled but machine is under fire and might
OOM and crash.
This patch exploits the new TCP early demux, to set a nocache
boolean in case incoming TCP frame is for a not yet ESTABLISHED or
TIMEWAIT socket.
This 'nocache' boolean is then used in case dst entry is not found in
route cache, to create an unhashed dst entry (DST_NOCACHE)
SYN-cookie-ACK sent use a similar mechanism (ipv4: tcp: dont cache
output dst for syncookies), so after this patch, a machine is able to
absorb a DDOS synflood attack without polluting its IP route cache.
