Currently, a nexthop group is destroyed when the last FIB entry is
detached from it.
When nexthop objects are supported, this can no longer be the case, as
the group is a separate object whose lifetime is managed by user space.
Add an indication if a nexthop group can be destroyed and always set it
to true for the existing IPv4 and IPv6 nexthop groups.

Each FIB entry has a type (e.g., remote, local) that determines how the
entry is programmed to the device. In order to determine if the entry is
local (directly connected) or remote (has a gateway) the relevant FIB
info structures (e.g., 'struct fib_info') are checked.
When entries that use nexthop objects are supported, these checks will
need to be changed to take into account 'struct nexthop'.
Instead, first associate the entry with a nexthop group so that the next
patch could determine the entry's type based on the associated nexthop
group's type.

====================
Fix several bad kernel-doc markups
Kernel-doc has always be limited to a probably bad documented
rule:
The kernel-doc markups should appear *imediatelly before* the
function or data structure that it documents.
On other words, if a C file would contain something like this:
/**
* foo - function foo
* @args: foo args
*/
static inline void bar(int args);
/**
* bar - function bar
* @args: foo args
*/
static inline void foo(void *args);
The output (in ReST format) will be:
.. c:function:: void bar (int args)
function foo
**Parameters**
``int args``
foo args
.. c:function:: void foo (void *args)
function bar
**Parameters**
``void *args``
foo args
Which is clearly a wrong result. Before this changeset,
not even a warning is produced on such cases.
As placing such markups just before the documented
data is a common practice, on most cases this is fine.
However, as patches touch things, identifiers may be
renamed, and people may forget to update the kernel-doc
markups to follow such changes.
This has been happening for quite a while, as there are
lots of files with kernel-doc problems.
This series address those issues and add a file at the
end that will enforce that the identifier will match the
kernel-doc markup, avoiding this problem from
keep happening as time goes by.

The DLCI driver (dlci.c) implements the Frame Relay protocol. However,
we already have another newer and better implementation of Frame Relay
provided by the HDLC_FR driver (hdlc_fr.c).
The DLCI driver's implementation of Frame Relay is used by only one
hardware driver in the kernel - the SDLA driver (sdla.c).
The SDLA driver provides Frame Relay support for the Sangoma S50x devices.
However, the vendor provides their own driver (along with their own
multi-WAN-protocol implementations including Frame Relay), called WANPIPE.
I believe most users of the hardware would use the vendor-provided WANPIPE
driver instead.
(The WANPIPE driver was even once in the kernel, but was deleted in
commit 8db60bcf3021 ("[WAN]: Remove broken and unmaintained Sangoma

====================
net: phy: add support for shared interrupts (part 2)
This patch set aims to actually add support for shared interrupts in
phylib and not only for multi-PHY devices. While we are at it,
streamline the interrupt handling in phylib.
For a bit of context, at the moment, there are multiple phy_driver ops
that deal with this subject:
- .config_intr() - Enable/disable the interrupt line.
- .ack_interrupt() - Should quiesce any interrupts that may have been
fired. It's also used by phylib in conjunction with .config_intr() to
clear any pending interrupts after the line was disabled, and before
it is going to be enabled.
- .did_interrupt() - Intended for multi-PHY devices with a shared IRQ
line and used by phylib to discern which PHY from the package was the
one that actually fired the interrupt.
- .handle_interrupt() - Completely overrides the default interrupt
handling logic from phylib. The PHY driver is responsible for checking
if any interrupt was fired by the respective PHY and choose
accordingly if it's the one that should trigger the link state machine.
From my point of view, the interrupt handling in phylib has become
somewhat confusing with all these callbacks that actually read the same
PHY register - the interrupt status. A more streamlined approach would
be to just move the responsibility to write an interrupt handler to the
driver (as any other device driver does) and make .handle_interrupt()
the only way to deal with interrupts.
Another advantage with this approach would be that phylib would gain
support for shared IRQs between different PHY (not just multi-PHY
devices), something which at the moment would require extending every
PHY driver anyway in order to implement their .did_interrupt() callback
and duplicate the same logic as in .ack_interrupt(). The disadvantage
of making .did_interrupt() mandatory would be that we are slightly
changing the semantics of the phylib API and that would increase
confusion instead of reducing it.
What I am proposing is the following:
- As a first step, make the .ack_interrupt() callback optional so that
we do not break any PHY driver amid the transition.
- Every PHY driver gains a .handle_interrupt() implementation that, for
the most part, would look like below:
irq_status = phy_read(phydev, INTR_STATUS);
if (irq_status < 0) {
phy_error(phydev);
return IRQ_NONE;
}
if (!(irq_status & irq_mask))
return IRQ_NONE;
phy_trigger_machine(phydev);
return IRQ_HANDLED;
- Remove each PHY driver's implementation of the .ack_interrupt() by
actually taking care of quiescing any pending interrupts before
enabling/after disabling the interrupt line.
- Finally, after all drivers have been ported, remove the
.ack_interrupt() and .did_interrupt() callbacks from phy_driver.
This patch set is part 2 of the entire change set and it addresses the
changes needed in 9 PHY drivers. The rest can be found on my Github
branch here:

In preparation of removing the .ack_interrupt() callback, we must replace
its occurrences (aka phy_clear_interrupt), from the 2 places where it is
called from (phy_enable_interrupts and phy_disable_interrupts), with
equivalent functionality.
This means that clearing interrupts now becomes something that the PHY
driver is responsible of doing, before enabling interrupts and after
clearing them. Make this driver follow the new contract.

In an attempt to actually support shared IRQs in phylib, we now move the
responsibility of triggering the phylib state machine or just returning
IRQ_NONE, based on the IRQ status register, to the PHY driver. Having
3 different IRQ handling callbacks (.handle_interrupt(),
.did_interrupt() and .ack_interrupt() ) is confusing so let the PHY
driver implement directly an IRQ handler like any other device driver.
Make this driver follow the new convention.

In preparation of removing the .ack_interrupt() callback, we must replace
its occurrences (aka phy_clear_interrupt), from the 2 places where it is
called from (phy_enable_interrupts and phy_disable_interrupts), with
equivalent functionality.
This means that clearing interrupts now becomes something that the PHY
driver is responsible of doing, before enabling interrupts and after
clearing them. Make this driver follow the new contract.
