5b4d10f5e0 qlcnic: use the correct ring in qlcnic_83xx_process_rcv_ring_diag()
There is a static checker warning here "warn: mask and shift to zero"
and the code sets "ring" to zero every time.  From looking at how
QLCNIC_FETCH_RING_ID() is used in qlcnic_83xx_process_rcv_ring() the
qlcnic_83xx_hndl() should be removed.

3f4c68cfde net: thunderx: Fix link status reporting
Check for SMU RX local/remote faults along with SPU LINK
status. Otherwise at times link is UP at our end but DOWN
at link partner's side. Also due to an issue in BGX it's
rarely seen that initialization doesn't happen properly
and SMU RX reports faults with everything fine at SPU.
This patch tries to reinitialize LMAC to fix it.

Also fixed LMAC disable sequence to properly bring down link.

If we have a system which uses fixed PHY devices and calls
fixed_phy_register() then fixed_phy_unregister() we can exhaust the

0622cab034 bonding: fix 802.3ad aggregator reselection
Since commit 7bb11dc9f5 ("bonding: unify all places where
actor-oper key needs to be updated."), the logic in bonding to handle
selection between multiple aggregators has not functioned.

	This affects only configurations wherein the bonding slaves
connect to two discrete aggregators (e.g., two independent switches, each
with LACP enabled), thus creating two separate aggregation groups within a
single bond.

	The cause is a change in 7bb11dc9f5 to no longer set
AD_PORT_BEGIN on a port after a link state change, which would cause the
port to be reselected for attachment to an aggregator as if were newly
added to the bond.  We cannot restore the prior behavior, as it
contradicts IEEE 802.1AX 5.4.12, which requires ports that "become
inoperable" (lose carrier, setting port_enabled=false as per 802.1AX
5.4.7) to remain selected (i.e., assigned to the aggregator).  As the port
now remains selected, the aggregator selection logic is not invoked.

	A side effect of this change is that aggregators in bonding will
now contain ports that are link down.  The aggregator selection logic
does not currently handle this situation correctly, causing incorrect
aggregator selection.

	This patch makes two changes to repair the aggregator selection
logic in bonding to function as documented and within the confines of the
standard:

	First, the aggregator selection and related logic now utilizes the
number of active ports per aggregator, not the number of selected ports
(as some selected ports may be down).  The ad_select "bandwidth" and
"count" options only consider ports that are link up.

	Second, on any carrier state change of any slave, the aggregator
selection logic is explicitly called to insure the correct aggregator is
active.

a37503bc38 net: smsc911x: Fix bug where PHY interrupts are overwritten by 0
By default, mdiobus_alloc() sets the PHYs to polling mode, but a
pointer size memcpy means that a couple IRQs end up being overwritten
with a value of 0. This means that PHY_POLL is disabled and results
in unpredictable behavior depending on the PHY's location on the
MDIO bus. Remove that memcpy and the now unused phy_irq member to
force the SMSC911x PHYs into polling mode 100% of the time.

a0d26d5a4f qed*: Don't reset statistics on inner reload
Several user APIs can cause driver to perform an inner-reload.
Currently, doing this would cause the HW/FW statistics of the
adapter to reset, which isn't the expected behavior [statistics
should only reset on explicit unloads].

326439883e qed: Prevent VF from Tx-switching 'promisc'
Internal loopback in driver is based on two things - first
is the willingness of transmitter to use it [in case of VFs,
this can be forced based on VEPA/VEB] and secondly on another
vport classification configuration which should match the
packet's destination.

Current code allows non-linux VFs to configure a 'promisc'
mode on Tx, meaning all traffic sent by VF would be loopbacked
internally by firmware; This isn't considered a valid mode and
as such should be prevented by PF.

e6bd89232b qed: Correct default vlan behavior
When no vlan filter is configured, firmware has a configurable
default on whether to pass only untagged packets or all packets
regardless of their tagging. Driver currently doesn't set this
field in the necessary ramrod, causing the default to always be
'receive all'.

a9836cbb5f net: tilegx: use correct timespec64 type
The conversion to the 64-bit time based ptp methods left two instances
of 'struct timespec' in place. This is harmless because 64-bit
architectures define timespec64 as timespec, and this driver is
not used on 32-bit machines.

However, using 'struct timespec64' directly is obviously the right
thing to do, and will help us remove 'struct timespec' in the future.

ce449ba77a nfp: use correct index to mask link state irq
We were using an incorrect define to get the irq vector number.
NFP_NET_CFG_LSC is a control BAR offset, LSC interrupt vector
index is called NFP_NET_IRQ_LSC_IDX.  For machines with less
than 30 CPUs this meant that we were disabling/enabling IRQ 0.
For bigger hosts we were just playing with the 31st RX/TX
interrupt.

a547224dce mlx4e: Do not attempt to offload VXLAN ports that are unrecognized
The mlx4e driver does not support more than one port for VXLAN offload.  As
such expecting the hardware to offload other ports is invalid since it
appears the parsing logic is used to perform Tx checksum and segmentation
offloads.  Use the vxlan_port number to determine in which cases we can
apply the offload and in which cases we can not.

17471c7ba5 net: sfc: avoid -Wtype-limits warning
When building with -Wextra, we get a harmless warning from the
EFX_EXTRACT_OWORD32 macro:

ethernet/sfc/farch.c: In function 'efx_farch_test_registers':
ethernet/sfc/farch.c:119:30: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]
ethernet/sfc/farch.c:124:144: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]

ethernet/sfc/farch.c:124:731: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]

The macro and the caller are both correct, but we can avoid the
warning by changing the index variable to a signed type.
