last_keep_alive_jiffies is updated in probe and when a keep-alive
event is received.  In case the driver times-out on a keep-alive event,
it has high chances of continuously timing-out on keep-alive events.
This is because when the driver recovers from the keep-alive-timeout reset
the value of last_keep_alive_jiffies is very old, and if a keep-alive
event is not received before the next timer expires, the value of
last_keep_alive_jiffies will cause another keep-alive-timeout reset
and so forth in a loop.

Solution:
Update last_keep_alive_jiffies whenever the device is restored after
reset.

Bug:
In short the main issue is caused by the fact that the number of queues
is changed using ethtool after ena_probe() has been called and before
ena_up() was executed. Here is the full scenario in detail:

* ena_probe() is called when the driver is loaded, the driver is not up
  yet at the end of ena_probe().
* The number of queues is changed -> io_queue_count is changed as well -
  ena_up() is not called since the "dev_was_up" boolean in
  ena_update_queue_count() is false.
* ena_up() is called by the kernel (it's called asynchronously some
  time after ena_probe()). ena_setup_io_intr() is called by ena_up() and
  it uses io_queue_count to get the suitable irq lines for each msix
  vector. The function ena_request_io_irq() is called right after that
  and it uses msix_vecs - This value only changes during ena_probe() and
  ena_restore() - to request the irq vectors. This results in "Failed to
  request I/O IRQ" error for i > io_queue_count.

Numeric example:
* After ena_probe() io_queue_count = 8, msix_vecs = 9.
* The number of queues changes to 4 -> io_queue_count = 4, msix_vecs = 9.
* ena_up() is executed for the first time:
  ** ena_setup_io_intr() inits the vectors only up to io_queue_count.
  ** ena_request_io_irq() calls request_irq() and fails for i = 5.

How to reproduce:
simply run the following commands:
    sudo rmmod ena && sudo insmod ena.ko;
    sudo ethtool -L eth1 combined 3;

Fix:
Use ENA_MAX_MSIX_VEC(adapter->num_io_queues + adapter->xdp_num_queues)
instead of adapter->msix_vecs. We need to take XDP queues into
consideration as they need to have msix vectors assigned to them as well.
Note that the XDP cannot be attached before the driver is up and running
but in XDP mode the issue might occur when the number of queues changes
right after a reset trigger.
The ENA_MAX_MSIX_VEC simply adds one to the argument since the first msix
vector is reserved for management queue.

Overview:
We don't frequently change the msix vectors throughout the life cycle of
the driver. We do so in two functions: ena_probe() and ena_restore().
ena_probe() is only called when the driver is loaded. ena_restore() on the
other hand is called during device reset / resume operations.

We use num_io_queues for calculating and allocating the number of msix
vectors. At ena_probe() this value is equal to max_num_io_queues and thus
this is not an issue, however ena_restore() might be called after the
number of io queues has changed.

A possible bug scenario is as follows:

* Change number of queues from 8 to 4.
  (num_io_queues = 4, max_num_io_queues = 8, msix_vecs = 9,)
* Trigger reset occurs -> ena_restore is called.
  (num_io_queues = 4, max_num_io_queues =8 , msix_vecs = 5)
* Change number of queues from 4 to 6.
  (num_io_queues = 6, max_num_io_queues = 8, msix_vecs = 5)
* The driver will reset due to failure of check_for_rx_interrupt_queue()

Fix:
This can be easily fixed by always using max_num_io_queues to init the
msix_vecs, since this number won't change as opposed to num_io_queues.

net: bcmgenet: revisit MAC reset

Commit 3a55402c ("net: bcmgenet: use RGMII loopback for MAC
reset") was intended to resolve issues with reseting the UniMAC
core within the GENET block by providing better control over the
clocks used by the UniMAC core. Unfortunately, it is not
compatible with all of the supported system configurations so an
alternative method must be applied.

This commit set provides such an alternative. The first commit
reverts the previous change and the second commit provides the
alternative reset sequence that addresses the concerns observed
with the previous implementation.

This replacement implementation should be applied to the stable
branches wherever commit 3a55402c ("net: bcmgenet: use RGMII
loopback for MAC reset") has been applied.

Unfortunately, reverting that commit may conflict with some
restructuring changes introduced by commit 4f8d81b7 ("net:
bcmgenet: Refactor register access in bcmgenet_mii_config").
The first commit in this set has been manually edited to
resolve the conflict on net/master. I would be happy to help
stable maintainers with resolving any such conflicts if they
occur. However, I do not expect that commit to have been
backported to stable branch so hopefully the revert can be
applied cleanly.

As noted in commit 28c2d1a7 ("net: bcmgenet: enable loopback
during UniMAC sw_reset") the UniMAC must be clocked at least 5
cycles while the sw_reset is asserted to ensure a clean reset.

That commit enabled local loopback to provide an Rx clock from the
GENET sourced Tx clk. However, when connected in MII mode the Tx
clk is sourced by the PHY so if an EPHY is not supplying clocks
(e.g. when the link is down) the UniMAC does not receive the
necessary clocks.

This commit extends the sw_reset window until the PHY reports that
the link is up thereby ensuring that the clocks are being provided
to the MAC to produce a clean reset.

One consequence is that if the system attempts to enter a Wake on
LAN suspend state when the PHY link has not been active the MAC
may not have had a chance to initialize cleanly. In this case, we
remove the sw_reset and enable the WoL reception path as normal
with the hope that the PHY will provide the necessary clocks to
drive the WoL blocks if the link becomes active after the system
has entered suspend.

QorIQ DPAA ARM RDBs need internal delay on RGMII

v2: used phy_interface_mode_is_rgmii() to identify RGMII

The QorIQ DPAA 1 based RDB boards require internal delay on
both Tx and Rx to be set. The patch set ensures all RGMII
modes are treated correctly by the FMan driver and sets the
phy-connection-type to "rgmii-id" to restore functionality.
Previously Rx internal delay was set by board pull-ups and
was left untouched by the PHY driver. Since commit
1b3047b5 ("net: phy: realtek: add support for
configuring the RX delay on RTL8211F") the Realtek 8211F PHY
driver has control over the RGMII RX delay and it is
disabling it for other modes than RGMII_RXID and RGMII_ID.

Please note that u-boot in particular performs a fix-up of
the PHY connection type and will overwrite the values from
the Linux device tree. Another patch set was sent for u-boot
and one needs to apply that [1] to the boot loader, to ensure
this fix is complete, unless a different bootloader is used.

hsr: fix several bugs in generic netlink callback

This patchset is to fix several bugs they are related in
generic netlink callback in hsr module.

1. The first patch is to add missing rcu_read_lock() in
hsr_get_node_{list/status}().
The hsr_get_node_{list/status}() are not protected by RTNL because
they are callback functions of generic netlink.
But it calls __dev_get_by_index() without acquiring RTNL.
So, it would use unsafe data.

2. The second patch is to avoid failure of hsr_get_node_list().
hsr_get_node_list() is a callback of generic netlink and
it is used to get node information in userspace.
But, if there are so many nodes, it fails because of buffer size.
So, in this patch, restart routine is added.

3. The third patch is to set .netnsok flag to true.
If .netnsok flag is false, non-init_net namespace is not allowed to
operate generic netlink operations.
So, currently, non-init_net namespace has no way to get node information
because .netnsok is false in the current hsr code.

But, in the non-init_net namespace, these commands are not allowed
because .netnsok flag is false.
So, there is no way to get node information in the non-init_net namespace.
