Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.

In current implementation ice_update_phy_type enables all link modes
for selected speed. This approach doesn't work for 1000M speeds,
because both copper (1000baseT) and optical (1000baseX) standards
cannot be enabled at once.
Fix this, by adding the function `ice_set_phy_type_from_speed()`
for 1000M speeds.

Commit 34a897758efe ("ice: Add support for inner etype in switchdev")
added the ability to match on inner ethertype. A side effect of that change
is that it is now impossible to add some filters for protocols which do not
contain inner ethtype field. tc requires the protocol field to be specified
when providing certain other options, e.g. src_ip. This is a problem in
case of GTP - when user wants to specify e.g. src_ip, they also need to
specify protocol in tc command (otherwise tc fails with: Illegal "src_ip").
Because GTP is a tunnel, the protocol field is treated as inner protocol.
GTP does not contain inner ethtype field and the filter cannot be added.
To fix this, ignore the ethertype field in case of GTP filters.

The recent patch to make afs_getattr consult the server didn't account
for the pseudo-inodes employed by the dynamic root-type afs superblock
not having a volume or a server to access, and thus an oops occurs if
such a directory is stat'd.
Fix this by checking to see if the vnode->volume pointer actually points
anywhere before following it in afs_getattr().
This can be tested by stat'ing a directory in /afs. It may be
sufficient just to do "ls /afs" and the oops looks something like:

net: dsa: microchip: common spi probe for the ksz series switches - part 1
This patch series aims to refactor the ksz_switch_register routine to have the
common flow for the ksz series switch. At present ksz8795.c & ksz9477.c have
its own dsa_switch_ops and switch detect functionality.
In ksz_switch_register, ksz_dev_ops is assigned based on the function parameter
passed by the individual ksz8/ksz9477 switch register function. And then switch
detect is performed based on the ksz_dev_ops.detect hook. This patch modifies
the ksz_switch_register such a way that switch detect is performed first, based
on the chip ksz_dev_ops is assigned to ksz_device structure. It ensures the
common flow for the existing as well as LAN937x switches.
In the next series of patch, it will move ksz_dsa_ops and dsa_switch_ops
from ksz8795.c and ksz9477.c to ksz_common.c and have the common spi
probe all the ksz based switches.
Changes in v1
- Splitted the patch series into two.
- Replaced all occurrence of REG_PORT_STATUS_0 and PORT_FIBER_MODE to
KSZ8_PORT_STATUS_0 and KSZ8_PORT_FIBER_MODE.
- Separated the tag protocol and phy read/write patch into two.
- Assigned the DSA_TAG_PROTO_NONE as the default value for get_tag_protocol hook.
- Reduced the indentation level by using the if(!dev->dev_ops->mirror_add).
- Added the stp_ctrl_reg as a member in ksz_chip_data and removed the member
in ksz_dev_ops.
- Removed the r_dyn_mac_table, r_sta_mac_table and w_sta_mac_table from the
ksz_dev_ops since it is used only in the ksz8795.c.
Changes in RFC v2
- Fixed the compilation issue.
- Reduced the patch set to 15.

It's been reported that the recent fix for skipping the
component-binding with D-GPU caused a regression on some systems; it
resulted in the completely missing component binding with i915 GPU.
The problem was the use of pci_get_class() function. It matches with
the full PCI class bits, while we want to match only partially the PCI
base class bits. So, when a system has an i915 graphics device with
the PCI class 0380, it won't hit because we're looking for only the
PCI class 0300.
This patch fixes i915_gfx_present() to look up each PCI device and
match with PCI base class explicitly instead of pci_get_class().

During initialization of the NFP driver, a file name for loading
application firmware is composed using the NIC's AMDA information and port
type (count and speed). E.g.: "nic_AMDA0145-1012_2x10.nffw".
In practice there may be many variants for each NIC type, and many of the
variants relate to assembly components which do not concern the driver and
application firmware implementation. Yet the current scheme leads to a
different application firmware file name for each variant, because they
have different AMDA information.
To reduce proliferation of content-duplicated application firmware images
or symlinks, the NIC's management firmware will only expose differences
between variants that need different application firmware via a newly
introduced hwinfo, "nffw.partno".
Use of the existing hwinfo, "assembly.partno", is maintained in order to
support for NICs with management firmware that does not expose
"nffw.partno".

headroom reduced, so add a skb_cow() before so that headroom is
increased if necessary.
nf_do_netdev_egress() assumes skb ownership (it normally ends with
a call to dev_queue_xmit), so we must free the packet on error.

Currently the Conexant codec driver sets up the beep NID after calling
snd_hda_gen_parse_auto_config(). It turned out that this results in
the insufficient setup for the beep control, as the generic parser
handles the fake path in snd_hda_gen_parse_auto_config() only if the
beep_nid is set up beforehand.
For dealing with the beep widget properly, call cx_auto_parse_beep()
before snd_hda_gen_parse_auto_config() call.

====================
mlxsw: Unified bridge conversion - part 1/6
This set starts converting mlxsw to the unified bridge model and mainly
adds new device registers and extends existing ones that will be used in
follow-up patchsets.
High-level summary
==================
The unified bridge model is a new way of managing low-level device
objects such as filtering identifiers (FIDs). The conversion moves a lot
of logic out of the device's firmware towards the driver, but its main
selling point is that it allows to overcome various scalability issues
related to the amount of entries that need to be programmed to the
device.
The only (intended) user visible changes of the conversion are
improvement in resource utilization and ability to support more router
interfaces (RIFs) in Spectrum-{2,3}.
Details
=======
Commit 50853808ff4a ("Merge branch
'mlxsw-Prepare-for-VLAN-aware-bridge-w-VxLAN'") converted mlxsw to
emulate 802.1Q FIDs (represent VLANs in a VLAN-aware bridge) using
802.1D FIDs (represent VLAN-unaware bridges). This was necessary because
at that time VNI could not be assigned to 802.1Q FIDs, which effectively
meant that mlxsw could not support VXLAN with VLAN-aware bridges.
The downside of this approach is that multiple {Port,VID}->FID entries
are required in order to classify incoming traffic to a FID, as opposed
to a single VID->FID entry that can be used with actual 802.1Q FIDs.
For example, if 10 ports are members in the same VLAN-aware bridge and
the same 100 VLANs are configured on each port, then only 100 VID->FID
entries are required with 802.1Q FIDs, whereas 1000 {Port,VID}->FID
entries are required with emulated 802.1Q FIDs.
The above limitation is the result of various assumptions that were made
in the design of the API that was exposed to software. In the unified
bridge model the API is much more "raw" and therefore avoids these
assumptions, allowing software to configure the device in a more
efficient manner.

Router interfaces (RIFs) constructed on top of VLAN-aware bridges are of
"VLAN" type, whereas RIFs constructed on top of VLAN-unaware bridges of
"FID" type.
In other words, the RIF type is derived from the underlying FID type.
VLAN RIFs are used on top of 802.1Q FIDs, whereas FID RIFs are used on
top of 802.1D FIDs.
Currently 802.1Q FIDs are emulated using 802.1D FIDs, and therefore VLAN
RIFs are emulated using FID RIFs.
As part of converting the driver to use unified bridge, 802.1Q FIDs and
VLAN RIFs will be used.
Add the relevant fields to RITR register, add pack() function for VLAN
RIF and rename one field to fit the internal name.

As preparation for unified bridge model, add support for VNI->FID mapping
via SVFA register.
When performing VXLAN encapsulation, the VXLAN header needs to contain a
VNI. This VNI is derived from the FID classification performed on
ingress, through which the ingress RIF is also determined.
Similarly, when performing VXLAN decapsulation, the FID of the packet
needs to be determined. This FID is derived from VNI classification
performed during decapsulation.
In the old model, both entries (i.e., FID->VNI and VNI->FID) were
configured via SFMR.vni.
In the new model, where ingress is separated from egress, ingress
configuration (VNI->FID) is performed via SVFA, while SFMR only
configures egress (FID->VNI).
Add 'vni' field to SVFA, add new mapping table - VNI to FID, add new
pack() function for VNI mapping and edit the comment in SFMR.

As preparation for unified bridge model, add REIV register for future use.
In the past, firmware would take care of the above mentioned mapping,
but in the new model this should be done by software using REIV register.
REIV register supports a simultaneous update of 256 ports using
'port_page' field. When 'port_page'=0 the records represent ports
0-255, when 'port_page'=1 the records represent ports 256-511 and so

SFGC register maps {packet type, bridge type} -> {MID base, table type}.
As preparation for unified bridge model, remove 'mid' field and add
'mid_base' field.
The MID index (index to PGT table which maps MID to local port list and
SMPE index) is a result of 'mid_base' + 'fid_offset'. Using the legacy
bridge model, firmware configures 'mid_base'. However, using the new model,
software is responsible to configure it via SFGC register.
The 'mid_base' is configured per {packet type, bridge type}, for
example, for {Unicast, .1Q}, {Broadcast, .1D}.
Add the field 'mid_base' to SFGC register and increase the length of the
register accordingly.
Remove the field 'mid' as currently it is ignored by the device, its use
is an old leftover.

SFMR register creates and configures FIDs. As preparation for unified

The PGT (Port Group) table maps multicast ID (MID) to
{local port list, SMPE index} on Spectrum-1 and to {local port list} on
the other ASICs.
In the legacy model, software did not interact with this table directly.
Instead, it was accessed by firmware in response to registers such as
SFTR and SMID.
In the new model, the SFTR register is deprecated and software has full
control over the PGT table using the SMID register.
The configuration of MDB entries (using SFD) is unchanged, but flooding
configuration is completely different.
SFGC register maps {packet type, bridge type} -> {MID base, table type},
then with FID and FID-offset which are configured via SFMR, the MID index
is obtained.

802.1q FIDs and vFIDs using two types which are supported.
