Call bnxt_cfg_rx_mode() in bnxt_init_chip() to setup uc_list and
mc_list mac address filters. Before the patch, uc_list is not
setup again after chip reset (such as ethtool ring size change)
and macvlans don't work any more after that.

For PF, the bp->pf.mac_addr always holds the permanent MAC
addr assigned by the HW. For VF, the bp->vf.mac_addr always
holds the administrator assigned VF MAC addr. The random
generated VF MAC addr should never get stored to bp->vf.mac_addr.
This way, when the VF wants to change the MAC address, we can tell
if the adminstrator has already set it and disallow the VF from
changing it.

The existing ndo_set_mac_address only copies the new MAC addr
and didn't set the new MAC addr to the HW. The correct way is
to delete the existing default MAC filter from HW and add
the new one. Because of RFS filters are also dependent on the
default mac filter l2 context, the driver must go thru
close_nic() to delete the default MAC and RFS filters, then
open_nic() to set the default MAC address to HW.

If the driver is used on an ARM platform with SPARSE_IRQ defined,
semantics of NR_IRQS is different (minimal value of virtual irqs) and
by default it is set to 16, see arch/arm/include/asm/irq.h.
This value may be less than the actual number of virtual irqs, which
may break the driver initialization. The check removal allows to use
the driver on such a platform, and, if irq controller driver works
correctly, the check is not needed on legacy platforms.

Since Armada 38x SoC can support IP checksum for jumbo frames only on
a single port, it means that this feature should be enabled per-port,
rather than for the whole SoC.
This patch enables setting custom TX IP checksum limit by adding new
optional property to the mvneta device tree node. If not used, by
default 1600B is set for "marvell,armada-370-neta" and 9800B for other
strings, which ensures backward compatibility. Binding documentation

In the actual RX processing, there is same error path for both descriptor
ring refilling and building skb fails. This is not correct, because after
successful refill, the ring is already updated with newly allocated
buffer. Then, in case of build_skb() fail, hitherto code left the original
buffer unmapped.
This patch fixes above situation by swapping error check of skb build with
DMA-unmap of original buffer.

While testing on a network environment with not standard MTU (e.g. 3000),
a panic occurred if an incoming packet had a length greater than rx skb

Commit 77b0a09967 ("cdc-ncm: use common parser") added a dangerous
new trust in the CDC functional descriptors presented by the device,
unconditionally assuming that any device handled by the driver has
a CDC Union descriptor.
This descriptor is required by the NCM and MBIM specs, but crashing
on non-compliant devices is still unacceptable. Not only will that
allow malicious devices to crash the kernel, but in this case it is
also well known that there are non-compliant real devices on the
market - as shown by the comment accompanying the IAD workaround
in the same function.
The Sierra Wireless EM7305 is an example of such device, having
a CDC header and a CDC MBIM descriptor but no CDC Union:
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 12
bAlternateSetting 0
bNumEndpoints 1
bInterfaceClass 2 Communications
bInterfaceSubClass 14
bInterfaceProtocol 0
iInterface 0
CDC Header:
bcdCDC 1.10
CDC MBIM:
bcdMBIMVersion 1.00
wMaxControlMessage 4096
bNumberFilters 16
bMaxFilterSize 128
wMaxSegmentSize 4064
bmNetworkCapabilities 0x20
8-byte ntb input size
Endpoint Descriptor:
..
The conversion to a common parser also left the local cdc_union
variable untouched. This caused the IAD workaround code to be applied
to all devices with an IAD descriptor, which was never intended. Finish
the conversion by testing for hdr.usb_cdc_union_desc instead.

According to SJA1000 data sheet error-warning (EI) interrupt is not
cleared by setting the controller in to reset-mode.
Then if we have the following case:
- system is suspended (echo mem > /sys/power/state) and SJA1000 is left
in operating state
- A bus error condition occurs which activates EI interrupt, system is
still suspended which means EI interrupt will be not be handled nor
cleared.
If the above two events occur, on resume there is no way to return the
SJA1000 to operating state, except to cycle power to it.
By simply reading the IR register on start we will clear any previous
conditions that could be present.

The tulip driver causes annoying build-time warnings for allmodconfig
builds for all recent architectures:
dec/tulip/winbond-840.c:910:2: warning: #warning Processor architecture undefined
dec/tulip/tulip_core.c:101:2: warning: #warning Processor architecture undefined!
This is the last remaining warning for arm64, and I'd like to get rid of
it. We don't really know the cache line size, architecturally it would
be at least 16 bytes, but all implementations I found have 64 or 128
bytes. Configuring tulip for 32-byte lines as we do on ARM32 seems to
be the safe but slow default, and nobody who cares about performance these
days would use a tulip chip anyway, so we can just use that.
To save the next person the job of trying to find out what this is for
and picking a default for their architecture just to kill off the warning,
I'm now removing the preprocessor #warning and turning it into a pr_warn
or dev_warn that prints the equivalent information when the driver gets
loaded.

This patch was originally authored by Ben Pope, but it got held up by
issues in the commit message, so I'm resubmitting it on his behalf.
I've extensively used a kernel with this patch on a System76 serw9
laptop and am quite confident it works well (at least on the hardware I
have available for testing).
Note that as a favor to System76, Ubuntu has been carrying this as a
sauce patch in their 4.2 based Wily kernel, which presumably has given
it real-world testing on other E2400 equipped hardware (I don't know of
any Ubuntu kernel bugs filed about it):

By default the driver allowed incorrect frames to be received. What is
worse the code does not handle very short frames correctly. The FCS
length is unconditionally subtracted, and the underflow can cause
skb_put to be called with large number after implicit cast to unsigned.
And indeed, an skb_over_panic() was observed with via-velocity.
This removes the module parameter as it does not work in it's
current state, and should be implemented via NETIF_F_RXALL if needed.

Add support for IP1000A chips to dl2k driver.
IP1000A chip looks like a TC9020 with integrated PHY.
This allows IP1000A chips to work reliably because the ipg driver is
buggy - it loses packets under load and then completely stops
transmitting data.
Tested with Asus NX1101 v2.0 at 10, 100 and 1000Mbps:
vendor=0x13f0 device=0x1023 (rev 0x41)
subsystem vendor=0x1043 device=0x8180
MAC address registers access needed to be changed from 8-bit to 16-bit
because 8-bit does not work on IP1000A. 8-bit access is not even
allowed in the TC9020 datasheet (although it worked). 16-bit access
works on both.
Tested that it does not break D-Link DGE-550T (DL-2000 chip, probably
a rebranded TC9020):
vendor=0x1186 device=0x4000 (rev 0x0c)

Prevent outgoing multicast frames from looping back to the RX queue.
By introducing new HW capability self_lb_en_modifiable, which indicates
the support to modify self_lb_en bit in modify_tir command.
When this capability is set we can prevent TIRs from sending back
loopback multicast traffic to their own RQs, by "refreshing TIRs" with
modify_tir command, on every time new channels (SQs/RQs) are created at
device open.
This is needed since TIRs are static and only allocated once on driver
load, and the loopback decision is under their responsibility.
Fixes issues of the kind:
"IPv6: eth2: IPv6 duplicate address fe80::e61d:2dff:fe5c:f2e9 detected!"
The issue is seen since the IPv6 solicitations multicast messages are
loopedback and the network stack thinks they are coming from another host.

When entering D3, we need to use hardcoded key indices because the
firmware requires that. To do so, we are overwriting the HW key index
in the keyconf structure, which makes it impossible to reuse the
indices that were used before entering D3. Additionally, we overwrite
all the non-PTK keys with index 1, because the firmware only allows
one non-PTK key to be set. This is bad, because when we resume, we
may try to set more than one key with index 1, which will obviously
fail.
To fix this, allow the callers to set a pre-defined index to use in
iwl_mvm_set_sta_key() instead of relying on the hw_key_idx value from
the keyconf struct (which requires overwriting it). In normal cases,
the caller can pass STA_KEY_IDX_INVALID, which will cause a new key
offset to be chosen. During HW_RESTART, we pass the offset that is in
use. And during D3 entry, we pass the hardcoded indices we need to
use.
Additionally, don't clear the fw_key_table in D3 entry, so that the
flags are still set with the pre-D3 values when exiting D3.

Add some new PCI IDs for the 8260 series which were missing.
The following sub-system IDs were added:
0x0130, 0x1130, 0x0132, 0x1132, 0x1150, 0x8110, 0x9110, 0x8130,

Pull SCSI target updates from Nicholas Bellinger:
"This series contains HCH's changes to absorb configfs attribute
->show() + ->store() function pointer usage from it's original
tree-wide consumers, into common configfs code.
It includes usb-gadget, target w/ drivers, netconsole and ocfs2
changes to realize the improved simplicity, that now renders the
original include/target/configfs_macros.h CPP magic for fabric drivers
and others, unnecessary and obsolete.
And with common code in place, new configfs attributes can be added
easier than ever before.
Note, there are further improvements in-flight from other folks for
v4.5 code in configfs land, plus number of target fixes for post -rc1
code"
In the meantime, a new user of the now-removed old configfs API came in
through the char/misc tree in commit 7bd1d4093c ("stm class: Introduce
an abstraction for System Trace Module devices").
This merge resolution comes from Alexander Shishkin, who updated his stm
class tracing abstraction to account for the removal of the old
show_attribute and store_attribute methods in commit 517982229f
("configfs: remove old API") from this pull. As Alexander says about
that patch:
"There's no need to keep an extra wrapper structure per item and the
awkward show_attribute/store_attribute item ops are no longer needed.
This patch converts policy code to the new api, all the while making
the code quite a bit smaller and easier on the eyes.

Building dwmac-ipq806x on a 64-bit architecture produces a harmless
warning from gcc:
stmmac/dwmac-ipq806x.c: In function 'ipq806x_gmac_probe':
include/linux/bitops.h:6:19: warning: overflow in implicit constant conversion [-Woverflow]
val = QSGMII_PHY_CDR_EN |
stmmac/dwmac-ipq806x.c:333:8: note: in expansion of macro 'QSGMII_PHY_CDR_EN'
#define QSGMII_PHY_CDR_EN BIT(0)
#define BIT(nr) (1UL << (nr))
This is a result of the type conversion rules in C, when we take the
logical OR of multiple different types. In particular, we have
and unsigned long
QSGMII_PHY_CDR_EN == BIT(0) == (1ul << 0) == 0x0000000000000001ul
and a signed int
0xC << QSGMII_PHY_TX_DRV_AMP_OFFSET == 0xc0000000
which together gives a signed long value
0xffffffffc0000001l
and when this is passed into a function that takes an unsigned int type,
gcc warns about the signed overflow and the loss of the upper 32-bits that
are all ones.
This patch adds 'ul' type modifiers to the literal numbers passed in
here, so now the expression remains an 'unsigned long' with the upper
bits all zero, and that avoids the signed overflow and the warning.

Commit a70587b338 ("ath10k: configure copy engine 5 for HTT messages")
introduced to use the unused CE5 for target to host message. For the device
like QCA6174, CE5 already assigned for other feature. So for QCA6174, override
the CE5 configuration and use the CE1 instead.
This patch is based on Rajkumar's earlier patch.

A follow up patch introducing a QCA9377 hw1.0 support will need
this device identification helper for an explicit distinction of
HWs, as apparently both QCA6174 hw3.0 and QCA9377 share the same BMI

added we were just lucky we did not overlap with the same chip_id_rev.
