Device supports setting of a single fec mode at a time, enforce this
by bitmap_weight == 1. Input from fec command is in u32, avoid cast to
unsigned long and use bitmap_from_arr32 to populate bitmap safely.

net: qualcomm: rmnet: Enable Mapv5
This series introduces the MAPv5 packet format.
Patch 0 documents the MAPv4/v5.
Patch 1 introduces the MAPv5 and the Inline checksum offload for RX/Ingress.
Patch 2 introduces the MAPv5 and the Inline checksum offload for TX/Egress.
A new checksum header format is used as part of MAPv5.For RX checksum offload,
the checksum is verified by the HW and the validity is marked in the checksum
header of MAPv5. For TX, the required metadata is filled up so hardware can
compute the checksum.
v1->v2:
- Fixed the compilation errors, warnings reported by kernel test robot.
- Checksum header definition is expanded to support big, little endian
formats as mentioned by Jakub.
v2->v3:
- Fixed compilation errors reported by kernel bot for big endian flavor.
v3->v4:
- Made changes to use masks instead of C bit-fields as suggested by Jakub/Alex.
v4->v5:
- Corrected checkpatch errors and warnings reported by patchwork.
v5->v6:
- Corrected the bug identified by Alex and incorporated all his comments.
v6->v7:
- Removed duplicate inclusion of linux/bitfield.h in rmnet_map_data.c
v7->v8:
- Have addressed comments given by JAkub on v7 patches.
- As suggested by Jakub, skb_cow_head() is used instead of expanding
the head directly. This is now done in rmnet_map_egress_handler().

Adding support for MAPv5 egress packets.
This involves adding the MAPv5 header and setting the csum_valid_required
in the checksum header to request HW compute the checksum.
Corresponding stats are incremented based on whether the checksum is
computed in software or HW.
New stat has been added which represents the count of packets whose
checksum is calculated by the HW.

Adding support for processing of MAPv5 downlink packets.
It involves parsing the Mapv5 packet and checking the csum header
to know whether the hardware has validated the checksum and is
valid or not.
Based on the checksum valid bit the corresponding stats are
incremented and skb->ip_summed is marked either CHECKSUM_UNNECESSARY
or left as CHEKSUM_NONE to let network stack revalidate the checksum
and update the respective snmp stats.
Current MAPV1 header has been modified, the reserved field in the
Mapv1 header is now used for next header indication.

iwl-next Intel Wired LAN Driver Updates 2021-06-01
This pull request is targeting net-next and rdma-next branches.
These patches have been reviewed by netdev and rdma mailing lists[1].
This series adds RDMA support to the ice driver for E810 devices and
converts the i40e driver to use the auxiliary bus infrastructure
for X722 devices. The PCI netdev drivers register auxiliary RDMA devices
that will bind to auxiliary drivers registered by the new irdma module.
[1] https://lore.kernel.org/netdev/20210520143809.819-1-shiraz.saleem@intel.com/
---
v3:
- ice_aq_add_rdma_qsets(), ice_cfg_vsi_rdma(), ice_[ena|dis]_vsi_rdma_qset(),
and ice_cfg_rdma_fltr() no longer return ice_status
- Remove null check from ice_aq_add_rdma_qsets()
v2:
- Added patch 'i40e: Replace one-element array with flexible-array
member'
Changes since linked review (v6):
- Removed unnecessary checks in i40e_client_device_register() and
i40e_client_device_unregister()
- Simplified the i40e_client_device_register() API

net/sched: act_vlan: Fix modify to allow 0
Currently vlan modification action checks existence of vlan priority by
comparing it to 0. Therefore it is impossible to modify existing vlan
tag to have priority 0.
For example, the following tc command will change the vlan id but will
not affect vlan priority:
tc filter add dev eth1 ingress matchall action vlan modify id 300 \
priority 0 pipe mirred egress redirect dev eth2
The incoming packet on eth1:
ethertype 802.1Q (0x8100), vlan 200, p 4, ethertype IPv4
will be changed to:
ethertype 802.1Q (0x8100), vlan 300, p 4, ethertype IPv4
although the user has intended to have p == 0.
The fix is to add tcfv_push_prio_exists flag to struct tcf_vlan_params
and rely on it when deciding to set the priority.
The same flag is used to avoid dumping unset vlan priority.
Change Log:
v3 -> v4:
- revert tcf_vlan_get_fill_size change: total size calculation may race vs dump
v2 -> v3:
- Push assumes that the priority is being set
- tcf_vlan_get_fill_size accounts for priority existence
v1 -> v2:
- Do not dump unset priority and fix tests accordingly
- Test for priority 0 modification

When a netdev with active TLS offload goes down, tls_device_down is
called to stop the offload and tear down the TLS context. However, the
socket stays alive, and it still points to the TLS context, which is now
deallocated. If a netdev goes up, while the connection is still active,
and the data flow resumes after a number of TCP retransmissions, it will
lead to a use-after-free of the TLS context.
This commit addresses this bug by keeping the context alive until its
normal destruction, and implements the necessary fallbacks, so that the
connection can resume in software (non-offloaded) kTLS mode.
On the TX side tls_sw_fallback is used to encrypt all packets. The RX
side already has all the necessary fallbacks, because receiving
non-decrypted packets is supported. The thing needed on the RX side is
to block resync requests, which are normally produced after receiving
non-decrypted packets.
The necessary synchronization is implemented for a graceful teardown:
first the fallbacks are deployed, then the driver resources are released
(it used to be possible to have a tls_dev_resync after tls_dev_del).
A new flag called TLS_RX_DEV_DEGRADED is added to indicate the fallback
mode. It's used to skip the RX resync logic completely, as it becomes
useless, and some objects may be released (for example, resync_async,
which is allocated and freed by the driver).

In the case of merge, the page passed into page_to_skb() may be a head
page, not the page where the current data is located. So when trying to
get the buf where the data is located, we should get buf based on
headroom instead of offset.
This patch solves this problem. But if you don't use this patch, the
original code can also run, because if the page is not the page of the
current data, the calculated tailroom will be less than 0, and will not
enter the logic of build_skb() . The significance of this patch is to
modify this logical problem, allowing more situations to use
build_skb().

In merge mode, when xdp is enabled, if the headroom of buf is smaller
than virtnet_get_headroom(), xdp_linearize_page() will be called but the
variable of "headroom" is still 0, which leads to wrong logic after
entering page_to_skb().

This patch fixes the in-kernel mark setting by doing an additional
sk_dst_reset() which was introduced by commit 50254256f382 ("sock: Reset
dst when changing sk_mark via setsockopt"). The code is now shared to
avoid any further suprises when changing the socket mark value.
Fixes: 84d1c617402e ("net: sock: add sock_set_mark")

After the refactoring introduced in commit 87614b931c24 ("net: enetc:
create a common enetc_pf_to_port helper"), enetc_pf_to_port was coded up
to return -1 in case the passed PCIe device does not have a recognized
BDF.
Make sure the -1 value is checked by the callers, to appease static
checkers.

write_msg(netconsole.c:836) calls netpoll_send_udp after a call to
spin_lock_irqsave, which normally disables interrupts; but in PREEMPT_RT
this call just locks an rt_mutex without disabling irqs. In this case,
netpoll_send_udp is called with interrupts enabled.

Vadym Kochan says:
====================
Marvell Prestera Switchdev initial updates for firmware version 3.0
This series adds minimal support for firmware version 3.0 which
has such changes like:
- initial routing support
- LAG support
- events interrupt handling changes
Changes just make able to work with new firmware version but
supported features in driver will be added later.
New firmware version was recently merged into linux-firmware tree.
Added ability of loading previous fw major version if the latest one
is missing, also add support for previous FW ABI.
PATCH -> RFC:
1) Load previous fw version if the latest one is missing (suggested by Andrew Lunn)
2) Add support for previous FW ABI version (suggested by Andrew Lunn)
RFC v2:
1) Get rid of automatic decrementing of
major version but hard code it.
2) Print error message with file path if
previous FW could not be loaded.

Lets try to load previous fw version in case the latest one is missing on
existing system.
