The current semantic for napi_consume_skb() is that caller need
to provide non-zero budget when calling from NAPI context, and
breaking this semantic will cause hard to debug problem, because
_kfree_skb_defer() need to run in atomic context in order to push
the skb to the particular cpu' napi_alloc_cache atomically.
So add the lockdep_assert_in_softirq() to assert when the running
context is not in_softirq, in_softirq means softirq is serving or
BH is disabled, which has a ambiguous semantics due to the BH
disabled confusion, so add a comment to emphasize that.
And the softirq context can be interrupted by hard IRQ or NMI
context, lockdep_assert_in_softirq() need to assert about hard
IRQ or NMI context too.

Extend MRP to support LC mode(link check) for the interconnect port.
This applies only to the interconnect ring.
Opposite to RC mode(ring check) the LC mode is using CFM frames to
detect when the link goes up or down and based on that the userspace
will need to react.
One advantage of the LC mode over RC mode is that there will be fewer
frames in the normal rings. Because RC mode generates InTest on all
ports while LC mode sends CFM frame only on the interconnect port.
All 4 nodes part of the interconnect ring needs to have the same mode.
And it is not possible to have running LC and RC mode at the same time
on a node.
Whenever the MIM starts it needs to detect the status of the other 3
nodes in the interconnect ring so it would send a frame called
InLinkStatus, on which the clients needs to reply with their link
status.
This patch adds InLinkStatus frame type and extends existing rules on
how to forward this frame.

====================
net: phy: add support for shared interrupts (part 3)
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 3 (and final) of the entire change set and it
addresses the remaining PHY drivers that have not been migrated
previosly. Also, it finally removed the .did_interrupt() and
.ack_interrupt() callbacks since they are of no use anymore.
I do not have access to most of these PHY's, therefore I Cc-ed the
latest contributors to the individual PHY drivers in order to have
access, hopefully, to more regression testing.

Now that all the PHY drivers have been migrated to directly implement

With this patch, phylib has a proper support for shared IRQs (and not
just for multi-PHY devices. A PHY driver must implement both the
.handle_interrupt() and .config_intr() callbacks for the IRQs to be

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.
