In some functions we might be doing potential dereference
without a check. This patch puts the check in place for all these
functions. Also fix the "for loops" so that we increment VF at the
right place so that we always do it even if we are short-circuiting
the loop through continue.

Whenever we get a Tx hang we issue a PFR, which means we send AQ
messages to VFS about the reset coming. Unfortunately with the recent
fix to be able to send messages to all VFS which earlier was not
happening at all we now are sending messages to not just the VFS that
are up but also to VFS that are not up. AQ complains about this and
sends us an error in ARQ called LAN overflow event for a queue. We
check if the queue belongs to a VF and if it does we try to send a
vc_notify_vf_reset message to that VF. Well if the VF is not up/enabled
we will be entering this function with a non-active VF id. In this
function we were assuming VF struct is populated but it won't be if
the VF is not active.

xgene_enet_get_ring_size() returns a negative value in case of an error,
but its only caller in xgene_enet_create_desc_ring() currently uses the
return value directly as u32. Instead, check for a negative value first and
error out in case. Also move the call to xgene_enet_get_ring_size() before
devm_kzalloc() so we don't need to free anything in the error path.

Wei Yongjun provides a fix for i40e to resolve a sparse warning, where
a non-static function should be static.
Julia Lawall provides a fix for i40e which was found using Coccinelle,
where there was a typo in the name of the type given to sizeof().
Rickard Strandqvist provides a fix for i40e to replace the use of
strncpy() with strlcpy() to avoid strings that lack null termination.
Jean Sacren provides two e1000e fixes, first is a comment fix and second
removes an excessive space character in a debug message.

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

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.

The Linux kernel coding style guidelines suggest not using typedefs
for structure types. This patch gets rid of the typedef for board_info_t.
Also, the name of the structs is changed to drop the _t, to make the
name look less typedef-like.
The following Coccinelle semantic patch detects the cases:
@tn@
identifier i;
type td;
@@
-typedef
struct i { ... }
-td
;
@@
type tn.td;
identifier tn.i;
@@
-td
+ struct i

Of_node_put supports NULL as its argument, so the initial test is not
necessary.

* Changes required due to 16eecd9be4 ("dcbnl : Fix misleading
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)
* Prio queue info & tsa is no longer thrown away
v2: Print DCBx state transition messages only when debug is enabled

This matches what the other drivers using fixed-link support do and
restores the behaviour before commit 87009814cd ("ucc_geth: use the
new fixed PHY helpers") for the affected device trees (i.e. no
phy-handle and no fixed-link).

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.
