1621b94d2a tipc: fix memory leak of publications
Commit 1bb8dce57f ("tipc: fix memory
leak during module removal") introduced a memory leak issue: when
name table is stopped, it's forgotten that publication instances are
freed properly. Additionally the useless "continue" statement in
tipc_nametbl_stop() is removed as well.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates

This series contains updates to i40e and i40evf.

Jacob provides a i40e patch to remove ptp_tx_work() because it conflicts
with the interrupt-based handler and will cause spurious warning messages
to be displayed in the kernel log.  Since the hardware can properly trigger
an interrupt, we do not need to poll for an available timestamp in a work
queue any more.

Greg provides two patches for i40e, first to retain the MAC filter list
when changing a port VLAN.  Second fixes an issue where the function to
set the VF MAC address was not taking the port VLAN filter into account
when setting/clearing/resetting the VF's host administered MAC address.

Mitch provides three patches for i40evf, first adds support for getting
and setting RSS hashing options, RSS LUT entries, and getting the number
of device channels from ethtool.  Fixes a panic that woudl occur in the VF
if the PF driver failed or was removed from the host kernel.

Shannon adds driver version string to the driver version command so that
can be passed down through the firmware to low-level NC-SI functions.

Neerav provides several patches, first redistributes queue vectors after
DCB reconfiguration because the total number of queues that are configured
for a VSI may change based on a change in the total number of TCs enabled
as a result of a change in the DCB configuration based on DCBX.  Second,
allows the driver probe to continue when querying DCB config fails.
Lastly, provides changes to retrieve and store missing link config
information that was not being cached in the struct i40e_link_status.

Kevin provides a couple of patches, first to change a int variable type
to u16 to avoid a typecheck failure.  Second to update a function
parameters to remove an argument which is no longer used.

eab8c04573 tipc: move the delivery of named messages out of nametbl lock
Commit a89778d8ba ("tipc: add support
for link state subscriptions") introduced below possible deadlock
scenario:

       CPU0                          CPU1
T0:   tipc_publish()                 link_timeout()
T1:   tipc_nametbl_publish()         [grab node lock]*
T2:   [grab nametbl write lock]*     link_state_event()
T3:   named_cluster_distribute()     link_activate()
T4:   [grab node lock]*              tipc_node_link_up()
T5:                                  tipc_nametbl_publish()
T6:                                  [grab nametble write lock]*

The opposite order of holding nametbl write lock and node lock on
above two different paths may result in a deadlock. If we move the
the delivery of named messages via link out of name nametbl lock,
the reverse order of holding locks will be eliminated, as a result,
the deadlock will be killed as well.

0f8ee7fc5d qeth: Fix default queue setting in priority queueing
The default queue for queueing modes prio_queueing_prec and
prio_queueing_tos is supposed to be QETH_DEFAULT_QUEUE. However, neither
mode will reset the default default_out_queue value when enabled, leaving
a previously set value activate as the default.
E.g. enabling one of the fixed queueing modes, e.g. no_prio_queueing:0,
and successively switching to any of the prio_queueing_* modes will
leave default_out_queue at the previous (wrong) value 0.

d39a743511 ptp: validate the requested frequency adjustment.
PTP Hardware Clock drivers specify a maximum frequency adjustment that
their clocks can accommodate. Normally, user space programs will want to
respect the advertised limits. However, no kernel or driver code checks
that the dialed frequency offset is within the bounds, and out of range
values can lead to surprising results.

This patch fixes the issue by rejecting bad values.

266a164684 ethtool: exit the loop when invalid index occurs
The commit 3de0b59239 ("ethtool: Support for configurable RSS hash
key") introduced a new function ethtool_copy_validate_indir() with
full iteration of the loop to validate the ring indices, which could
be an overkill. To minimize the impact, we ought to exit the loop as
soon as the invalid index occurs for the very first time. The
remaining loop simply doesn't serve any more purpose.

0672a09183 i40e: Redistribute queue vectors after DCB reconfiguration
The queue vectors are originally distributed among the total
number of queues that are configured for a given VSI. The number
of queues that are configured for a VSI depends on the number of
TCs that are enabled for the VSI at VSI setup/creation time.

But, the total number of queues that are configured for a VSI may
change based on change in the total number of TCs enabled as a
result of change in DCB configuration based on DCBX.

Hence, it is required for the queue vectors to be redistributed
when the total queues that are configured for a given VSI changes.

Without redistributing the vectors the queues that are configured
for the newly enabled TCs may not be able to do any Tx/Rx.

2f7ef2f879 sched, cls: check if we could overwrite actions when changing a filter
When actions are attached to a filter, they are a part of the filter
itself, so when changing a filter we should allow to overwrite the actions
inside as well.

In my specific case, when I tried to _append_ a new action to an existing
filter which already has an action, I got EEXIST since kernel refused
to overwrite the existing one in kernel.

This patch checks if we are changing the filter checking NLM_F_CREATE flag
(Sigh, filters don't use NLM_F_REPLACE...) and then passes the boolean down
to actions. This fixes the problem above.

ddfbac07c0 qlcnic: Optimize MAC learning code
* Use rx_mac_learn instead of mac_learn and eSwitch flag check in Rx path of
  82xx adapter.
* Check for MAC filter overrun only after driver scans through cached MAC address list.
  This will help to update the time stamp of cached MAC addresses even if
  adapter runs out of MAC address filter limit.
* Remove expensive log thrown by driver when MAC address filters are exhausted

f716775026 qlcnic: Use pci_enable_msix_exact() instead of pci_enable_msix()
As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range()  or pci_enable_msi_exact()
and pci_enable_msix_range() or pci_enable_msix_exact()
interfaces.

eb11022dca FDDI: Reformat <linux/if_fddi.h> for 8-character tabs
Some of our FDDI support code has been apparently written with an
assumption that tabs are 4-character wide.  In preparation to the next
change this update reformats <linux/if_fddi.h> so that it stays within 79
columns and otherwise renders correctly with 8-character tabs.  No
functional change.

22e7987ae7 tipc: fix a possible memory leak
The commit a8b9b96e95 ("tipc: fix race
in disc create/delete") leads to the following static checker warning:

	net/tipc/discover.c:352 tipc_disc_create()
		warn: possible memory leak of 'req'

The risk of memory leak really exists in practice. Especially when
it's failed to allocate memory for "req->buf", tipc_disc_create()
doesn't free its allocated memory, instead just directly returns
with ENOMEM error code. In this situation, memory leak, of course,
happens.

8945ef3fa2 Merge branch 'systemport'
Florian Fainelli says:

====================
net: Broadcom SYSTEMPORT driver

This patchset adds support for the Broadcom SYSTEMPORT Ethernet MAC
controller which is used in the latest Broadcom BCM7xxx Set Top Box
System-on-a-Chip. This Ethernet MAC is interfaced to an internal
switch which will get a separate driver submitted later on.
