bnxt_restore_pf_fw_resources routine frees PF resources by calling
close_nic and allocates the resources back, by doing open_nic. However,
this is not needed, if the PF is already in closed state.
This bug causes the driver to call open the device and call request_irq()
when it is not needed. Ultimately, pci_disable_msix() will crash
when bnxt_en is unloaded.
This patch fixes the problem by skipping __bnxt_close_nic and
__bnxt_open_nic inside bnxt_restore_pf_fw_resources routine, if the
interface is not running.

Recent changes added the bnxt_init_int_mode() call in the driver's open
path whenever ring reservations are changed. This call was previously
only called in the probe path. In the open path, if MQPRIO TC has been
setup, the bnxt_init_int_mode() call would reset and mess up the MQPRIO
per TC rings.
Fix it by not re-initilizing bp->tx_nr_rings_per_tc in
bnxt_init_int_mode(). Instead, initialize it in the probe path only
after the bnxt_init_int_mode() call.

In some conditions when the driver fails to add a flow in HW and returns

In 664fcf123a (net: phy: Threaded interrupts allow some simplification)
the phy_interrupt system was changed to use a traditional threaded
interrupt scheme instead of a workqueue approach.
With this change, the phy status check moved into phy_change, which
did not report back to the caller whether or not the interrupt was
handled. This means that, in the case of a shared phy interrupt,
only the first phydev's interrupt registers are checked (since
phy_interrupt() would always return IRQ_HANDLED). This leads to
interrupt storms when it is a secondary device that's actually the
interrupt source.

Adding a macvlan device on top of a lowerdev that supports
the xfrm offloads fails with a new regression:
# ip link add link ens1f0 mv0 type macvlan
RTNETLINK answers: Operation not permitted
Tracing down the failure shows that the macvlan device inherits
the NETIF_F_HW_ESP and NETIF_F_HW_ESP_TX_CSUM feature flags
from the lowerdev, but with no dev->xfrmdev_ops API filled
in, it doesn't actually support xfrm. When the request is
made to add the new macvlan device, the XFRM listener for
NETDEV_REGISTER calls xfrm_api_check() which fails the new
registration because dev->xfrmdev_ops is NULL.
The macvlan creation succeeds when we filter out the ESP
feature flags in macvlan_fix_features(), so let's filter them
out like we're already filtering out ~NETIF_F_NETNS_LOCAL.
When XFRM support is added in the future, we can add the flags
into MACVLAN_FEATURES.
This same problem could crop up in the future with any other
new feature flags, so let's filter out any flags that aren't
defined as supported in macvlan.

The Spectrum ASIC doesn't support mirroring more than once from a single
binding point (which is a port-direction pair). Therefore detect that a
second binding of a given binding point is attempted.
To that end, extend struct mlxsw_sp_span_inspected_port to track whether
a given binding point is bound or not. Extend
mlxsw_sp_span_entry_port_find() to look for ports based on the full
unique key: port number, direction, and boundness.
Besides fixing the overt bug where configured mirrors are not offloaded,
this also fixes a more subtle bug: mlxsw_sp_span_inspected_port_del()
just defers to mlxsw_sp_span_entry_bound_port_find(), and that used to
find the first port with the right number (disregarding the type). Thus
by adding and removing egress and ingress mirrors in the right order,
one could trick the system into believing it has no egress mirrors when
in fact it did have some. That then caused that
mlxsw_sp_span_port_mtu_update() didn't update mirroring buffer when MTU
was changed.

Rdma requires ILT Memory to be allocated for it's QPs.
Each ILT entry points to a page used by several Rdma QPs.
To avoid allocating all the memory in advance, the rdma
implementation dynamically allocates memory as more QPs are
added, however it does not dynamically free the memory.
The memory should have been freed on rmmod qedr, but isn't.
This patch adds the memory freeing on rmmod qedr (currently
it will be freed with qed is removed).
An outcome of this bug, is that if qedr is unloaded and loaded
without unloaded qed, there will be no more RoCE traffic.
The reason these are related, is that the logic of detecting the
first QP ever opened is by asking whether ILT memory for RoCE has
been allocated.
In addition, this patch modifies freeing of the Task context to
always use the PROTOCOLID_ROCE and not the protocol passed,
this is because task context for iWARP and ROCE both use the
ROCE protocol id, as opposed to the connection context.

Intel Wired LAN Driver Updates 2018-03-05
This series contains fixes to e1000e only.
Benjamin Poirier provides all but one fix in this series, starting with
workaround for a VMWare e1000e emulation issue where ICR reads 0x0 on
the emulated device. Partially reverted a previous commit dealing with
the "Other" interrupt throttling to avoid unforeseen fallout from these
changes that are not strictly necessary. Restored the ICS write for
receive and transmit queue interrupts in the case that txq or rxq bits
were set in ICR and the Other interrupt handler read and cleared ICR
before the queue interrupt was raised. Fixed an bug where interrupts
may be missed if ICR is read while INT_ASSERTED is not set, so avoid the
problem by setting all bits related to events that can trigger the Other
interrupt in IMS. Fixed the return value for check_for_link() when
auto-negotiation is off.
Pierre-Yves Kerbrat fixes e1000e to use dma_zalloc_coherent() to make
sure the ring is memset to 0 to prevent the area from containing
garbage.

The firmware has a requirement that the P2P_DEVICE address should
be different from the address of the primary interface. When not
specified by user-space, the driver generates the MAC address for
the P2P_DEVICE interface using the MAC address of the primary
interface and setting the locally administered bit. However, the MAC
address of the primary interface may already have that bit set causing
the creation of the P2P_DEVICE interface to fail with -EBUSY. Fix this
by using a random address instead to determine the P2P_DEVICE address.

When autoneg is off, the .check_for_link callback functions clear the
get_link_status flag and systematically return a "pseudo-error". This means
that the link is not detected as up until the next execution of the
e1000_watchdog_task() 2 seconds later.

The 82574 specification update errata 12 states that interrupts may be
missed if ICR is read while INT_ASSERTED is not set. Avoid that problem by
setting all bits related to events that can trigger the Other interrupt in
IMS.
The Other interrupt is raised for such events regardless of whether or not
they are set in IMS. However, only when they are set is the INT_ASSERTED
bit also set in ICR.
By doing this, we ensure that INT_ASSERTED is always set when we read ICR
in e1000_msix_other() and steer clear of the errata. This also ensures that
ICR will automatically be cleared on read, therefore we no longer need to
clear bits explicitly.

Restores the ICS write for Rx/Tx queue interrupts which was present before
commit 16ecba59bc ("e1000e: Do not read ICR in Other interrupt", v4.5-rc1)
but was not restored in commit 4aea7a5c5e
("e1000e: Avoid receiver overrun interrupt bursts", v4.15-rc1).
This re-raises the queue interrupts in case the txq or rxq bits were set in
ICR and the Other interrupt handler read and cleared ICR before the queue
interrupt was raised.

This partially reverts commit 4aea7a5c5e.
We keep the fix for the first part of the problem (1) described in the log
of that commit, that is to read ICR in the other interrupt handler. We
remove the fix for the second part of the problem (2), Other interrupt
throttling.
Bursts of "Other" interrupts may once again occur during rxo (receive
overflow) traffic conditions. This is deemed acceptable in the interest of
avoiding unforeseen fallout from changes that are not strictly necessary.
As discussed, the e1000e driver should be in "maintenance mode".

It was reported that emulated e1000e devices in vmware esxi 6.5 Build
7526125 do not link up after commit 4aea7a5c5e ("e1000e: Avoid receiver
overrun interrupt bursts", v4.15-rc1). Some tracing shows that after
e1000e_trigger_lsc() is called, ICR reads out as 0x0 in e1000_msix_other()
on emulated e1000e devices. In comparison, on real e1000e 82574 hardware,
icr=0x80000004 (_INT_ASSERTED | _LSC) in the same situation.
Some experimentation showed that this flaw in vmware e1000e emulation can
be worked around by not setting Other in EIAC. This is how it was before
16ecba59bc ("e1000e: Do not read ICR in Other interrupt", v4.5-rc1).

The netvsc device should propagate filters to the SR-IOV VF
device (if present). The flags also need to be propagated to the
VF device as well. This only really matters on local Hyper-V
since Azure does not support multiple addresses.

When VF is used for accelerated networking it will likely have
more queues (and different policy) than the synthetic NIC.
This patch defers the queue policy to the VF so that all the
queues can be used. This impacts workloads like local generate UDP.

There is a race between napi_reschedule and re-enabling interrupts
which could lead to missed host interrrupts. This occurs when
interrupts are re-enabled (hv_end_read) and vmbus irq callback
(netvsc_channel_cb) has already scheduled NAPI.
