Correct typo in the name of the type given to sizeof. Because it is the
size of a pointer that is wanted, the typo has no impact on compilation or
execution.
This problem was found using Coccinelle (http://coccinelle.lip6.fr/). The
semantic patch used can be found in message 0 of this patch series.

In case we configured the adapter to be a wake up source from
Wake-on-LAN, but we never actually woke up using Wake-on-LAN, we will
leave the adapter in MagicPacket matching mode, which prevents any other
type of packets from reaching the RX engine. Fix this by calling
bcmgenet_power_up() with GENET_POWER_WOL_MAGIC to restore the adapter
configuration in bcmgenet_resume().
The second problem we had was an imbalanced clock disabling in
bcmgenet_wol_resume(), the Wake-on-LAN slow clock is only enabled in
bcmgenet_suspend() if we configured Wake-on-LAN, yet we unconditionally
disabled the clock in bcmgenet_wol_resume().

When we bring the interface down, phy_stop() will schedule the PHY state
machine to call our link adjustment callback. By the time we do so, we
may have clock gated off the GENET hardware block, and this will cause
bus errors to happen in bcmgenet_mii_setup():
Make sure that we only touch the UMAC_CMD register when there is an
actual link. This is safe to do for two reasons:
- updating the Ethernet MAC registers only make sense when a physical
link is present
- the PHY library state machine first set phydev->link = 0 before
invoking phydev->adjust_link in the PHY_HALTED case

Make sure that we properly suspend and resume the PHY device when we
enter low power modes. We had two calls to bcmgenet_mii_reset() which
will issue a software-reset to the PHY without using the PHY library,
get rid of them since they are completely bogus and mess up with the PHY
library state. Make sure that we reset the PHY library cached values
(link, pause and duplex) to allow the link adjustment callback to be
invoked when needed.

bcmgenet_set_hw_params() will read the hardware version and compare it
with the one we are getting from Device Tree. Due to the clock being
enabled too late, bcmgenet_set_hw_params() will cause bus errors since
the GENET hardware block is still gated off by the time
bcmgenet_set_hw_params() is called, this will also make us fail the
version check since we will read the value 0 from the hardware.
Fix this by requesting the clock before the first piece of code that
needs to access hardware register.

There is a long known problem with the netfront/netback interface: if the guest
tries to send a packet which constitues more than MAX_SKB_FRAGS + 1 ring slots,
it gets dropped. The reason is that netback maps these slots to a frag in the
frags array, which is limited by size. Having so many slots can occur since
compound pages were introduced, as the ring protocol slice them up into
individual (non-compound) page aligned slots. The theoretical worst case
scenario looks like this (note, skbs are limited to 64 Kb here):
linear buffer: at most PAGE_SIZE - 17 * 2 bytes, overlapping page boundary,
using 2 slots
first 15 frags: 1 + PAGE_SIZE + 1 bytes long, first and last bytes are at the
end and the beginning of a page, therefore they use 3 * 15 = 45 slots
last 2 frags: 1 + 1 bytes, overlapping page boundary, 2 * 2 = 4 slots
Although I don't think this 51 slots skb can really happen, we need a solution
which can deal with every scenario. In real life there is only a few slots
overdue, but usually it causes the TCP stream to be blocked, as the retry will
most likely have the same buffer layout.
This patch solves this problem by linearizing the packet. This is not the
fastest way, and it can fail much easier as it tries to allocate a big linear
area for the whole packet, but probably easier by an order of magnitude than
anything else. Probably this code path is not touched very frequently anyway.

as well, so revert that change.

The driver assumes that endpoint 4 is always an interrupt endpoint.
Unfortunately the type differs between high-speed and full-speed
configurations while in the former case it is indeed an interrupt
endpoint this is not true for the latter case - here it is a bulk
endpoint. When sending URBs with the wrong type the kernel will
generate a warning message including backtrace. In this specific
case there will be a huge amount of warnings which can bring the system
to freeze.
To fix this we are now sending URBs to endpoint 4 using the type
found in the endpoint descriptor.
A side note: The carl9170 firmware currently specifies endpoint 4 as
interrupt endpoint even in the full-speed configuration but this has
no relevance because before this firmware is loaded the endpoint type
is as described above and after the firmware is running the stick is not
reenumerated and so the old descriptor is used.

dcb_app->priority explanation")
* Driver was previously not aware of what DCBx version was negotiated by
firmware, this could lead to DCB app table in kernel or in firmware being
populated wrong since IEEE/CEE used different formats made clear by above
mentioned commit
* Driver was missing a couple of state transitions that could be caused
by other drivers that use chelsio hardware, resulting in incorrect behaviour
(the change that addresses this also flips the state machine to switch on
state instead of transition, hope this is okay in current window)

When the driver attaches to a device that has a phy handle the probe
routine returns with a reference to that node. This reference is
correctly dropped in the error path and the remove function. In the
fixed phy case however no reference is acquired and so the error path
might drop a reference the driver isn't holding. Fix that by getting a
reference to the MAC.

Make sure that fs_enet_probe is left with a reference to the phy node.
In the presence of a phy handle this is already the case as
of_parse_phandle returns a reference. In the fixed phy case a call to
of_node_get is necessary. Otherwise the error path and remove function
drop a reference the driver isn't holding.

For the fixed phy setup make sure to not overwrite a valid value of
phy_dn (that is holding a reference to a phy-handle) and also acquire a
reference to the MAC node to consistently return with the phy_dn pointer
holding a reference.
Also add the corresponding of_node_put in the error path and the remove
function.
