We need to keep initial st_nci_gates values in order for
nfc_hci_dev_connect_gates to create and open pipe when necessary.
For example after a firmware update CLF pipes are cleared. Changing
pipe values in st21nfca_gates was causing nfc_hci_dev_connect_gates
not using accurate pipes value.

Some gates might need to have their pipes explicitly created.
Add a call to nci_hci_create_pipe in nci_hci_connect_gate for
every gate that is different than NCI_HCI_LINK_MGMT_GATE or
NCI_HCI_ADMIN_GATE.
In case of an error when opening a pipe, like in hci layer,
delete the pipe if it was created.

When sending HCI data over NCI, HCI return code is part
of the NCI data. In order to get correctly the HCI return
code, we assume the NCI communication is successful and
extract the return code for the nci_hci functions return code.
This is done because nci_to_errno does not match hci return

bnxt_gro_skb() has unused variables when CONFIG_INET is not set. We
really cannot support hardware GRO if CONFIG_INET is not set, so
compile out bnxt_gro_skb() completely and define BNXT_FLAG_GRO to be 0

For an ACPI compatible system, the SCI (ACPI System Control
Interrupt) is used to wake the system up from suspend-to-idle.
Once the CPU is woken up by the SCI, the interrupt handler will
first check if the current IRQ has been configured for system
wakeup, so irq_pm_check_wakeup() is invoked to validate the IRQ
number. However, during suspend-to-idle, enable_irq_wake() is
called for acpi_gbl_FADT.sci_interrupt, although the IRQ number
that the SCI handler has been installed for should be passed to
it instead. Thus, if acpi_gbl_FADT.sci_interrupt happens to be
different from that number, ACPI interrupts will not be able to
wake up the system from sleep.
Fix this problem by passing the IRQ number returned by
acpi_gsi_to_irq() to enable_irq_wake() instead of
acpi_gbl_FADT.sci_interrupt.

However, the remapped IRQ returned by acpi_gsi_to_irq() should be

Currently when the system is trying to uninstall the ACPI interrupt
handler, it uses acpi_gbl_FADT.sci_interrupt as the IRQ number.
However, the IRQ number that the ACPI interrupt handled is installed
for comes from acpi_gsi_to_irq() and that is the number that should
be used for the handler removal.
Fix this problem by using the mapped IRQ returned from acpi_gsi_to_irq()
as appropriate.

The Rx BSY error interrupt indicates that a frame was
received and discarded due to lack of buffers, so it's
a rx ring overflow condition and has nothing to do with
with bad rx packets. Use the right counter.
BSY conditions happen when the SoC is under performance
stress. Doing *more* work in stress situations by trying
to schedule NAPI is not a good idea as the stressed system
becomes still more stressed. The Rx interrupt is already
at work making sure the NAPI is scheduled.
So calling gfar_receive() here does not help. This issue
was present since day 1.

Under one unusual circumstance it's possible to wrongly set
FILREN without enabling PRSDEP as well in the RCTRL register,
against the hardware specifications. With the default config
this does not happen because the default Rx offloads (Rx csum
and Rx VLAN) properly enable PRSDEP. But if anyone disables
all these offloads (via ethtool), we get a wrong configuration
were the Rx flow classification and hashing, and other Filer
based features (e.g. wake-on-filer interrupt) won't work.
This patch fixes the issue.
Also, account for Rx FCB insertion which happens every time
PRSDEP is set.

mvneta ethtool statistics
Sorry for v3 - I forgot to update the commit message on patch 1 as
requested by Marcin.
This short series adds ethtool statistics reporting to mvneta. Having
discussed with Andrew on IRC, we decided I'd pick up his patch into my
series.
My change for patch 1 compared to the previous RFC splits out the
reading of the statistics from the hardware into a separate function,
in order to facilitate work going on elsewhere to arrange for the
statistics to be preserved across a suspend/resume cycle.

The LIC doesn't deal with the different types of interrupts itself
but needs to forward calls to set the appropriate type to its parent
IRQ controller.
Without this fix all IRQs routed through the LIC will stay at the
initial EDGE type, while most of them should actually be level triggered.

Commit d17cab4451df1 ("irqchip: Kill off set_irq_flags usage") changed
the code of armada_370_xp_mpic_irq_map() from using set_irq_flags() to
irq_set_probe().
While the commit log seems to imply that there are no functional
changes, there are indeed functional changes introduced by this
commit: the IRQ_NOAUTOEN flag is no longer cleared. This functional
change causes a regression on Armada XP, which no longer works
properly after suspend/resume because per-CPU interrupts remain
disabled.
Due to how the hardware registers work, the irq-armada-370-xp cannot
simply save/restore a bunch of registers at suspend/resume to make
sure that the interrupts remain in the same state after
resuming. Therefore, it relies on the kernel to say whether the
interrupt is disabled or not, using the irqd_irq_disabled()
function. This was all working fine while the IRQ_NOAUTOEN flag was
cleared.
With the change introduced by Rob Herring in d17cab4451df1, the
IRQ_NOAUTOEN flag is now set for all interrupts. irqd_irq_disabled()
returns false for per-CPU interrupts, and therefore our per-CPU
interrupts are no longer re-enabled after resume.
This commit works around this problem by clearing again the
IRQ_NOAUTOEN flags, so that we are back to the situation we had before
commit d17cab4451df1. This work around is proposed as a minimal fix
for the problem, while a better long-term solution is being worked on.
