86d1d8b72c net/ipv4: Fix missing raw_init when CONFIG_PROC_FS is disabled
Randy reported when CONFIG_PROC_FS is not enabled:
    ld: net/ipv4/af_inet.o: in function `inet_init':
    af_inet.c:(.init.text+0x42d): undefined reference to `raw_init'

Fix by moving the endif up to the end of the proc entries

4df5ce9bc0 lan743x: Enable driver to work with LAN7431
This driver was designed to work with both LAN7430 and LAN7431.
The only difference between the two is the LAN7431 has support
for external phy.

This change adds LAN7431 to the list of recognized devices
supported by this driver.

[...}

The reason is that the node timer handler sometimes needs to delete a
node which has been disconnected for too long. To do this, it grabs
the lock 'node_list_lock', which may at the same time be held by the
generic node cleanup function, tipc_node_stop(), during module removal.
Since the latter is calling del_timer_sync() inside the same lock, we
have a potential deadlock.

We fix this letting the timer cleanup function use spin_trylock()
instead of just spin_lock(), and when it fails to grab the lock it
just returns so that the timer handler can terminate its execution.
This is safe to do, since tipc_node_stop() anyway is about to
delete both the timer and the node instance.

cc59220541 lan743x: fix return value for lan743x_tx_napi_poll
The lan743x driver, when under heavy traffic load, has been noticed
to sometimes hang, or cause a kernel panic.

Debugging reveals that the TX napi poll routine was returning
the wrong value, 'weight'. Most other drivers return 0.
And call napi_complete, instead of napi_complete_done.

Additionally when creating the tx napi poll routine.
Changed netif_napi_add, to netif_tx_napi_add.

Updates for v3:
    changed 'fixes' tag to match defined format

Updates for v2:
use napi_complete, instead of napi_complete_done in
    lan743x_tx_napi_poll
use netif_tx_napi_add, instead of netif_napi_add for
    registration of tx napi poll routine

cc3ec656c7 Merge branch 'net-nsid-interpretation'
Nicolas Dichtel says:

====================
Ease to interpret net-nsid

The goal of this series is to ease the interpretation of nsid received in
netlink messages from other netns (when the user uses
NETLINK_F_LISTEN_ALL_NSID).

After this series, with a patched iproute2:

$ ip netns add foo
$ ip netns add bar
$ touch /var/run/netns/init_net
$ mount --bind /proc/1/ns/net /var/run/netns/init_net
$ ip netns set init_net 11
$ ip netns set foo 12
$ ip netns set bar 13
$ ip netns
init_net (id: 11)
bar (id: 13)
foo (id: 12)
$ ip -n foo netns set init_net 21
$ ip -n foo netns set foo 22
$ ip -n foo netns set bar 23
$ ip -n foo netns
init_net (id: 21)
bar (id: 23)
foo (id: 22)
$ ip -n bar netns set init_net 31
$ ip -n bar netns set foo 32
$ ip -n bar netns set bar 33
$ ip -n bar netns
init_net (id: 31)
bar (id: 33)
foo (id: 32)
$ ip netns list-id target-nsid 12
nsid 21 current-nsid 11 (iproute2 netns name: init_net)
nsid 22 current-nsid 12 (iproute2 netns name: foo)
nsid 23 current-nsid 13 (iproute2 netns name: bar)
$ ip -n bar netns list-id target-nsid 32 nsid 31
nsid 21 current-nsid 31 (iproute2 netns name: init_net)

v3 -> v4:
  - patch 5/5: fix imbalance lock in error path

v2 -> v3:
  - patch 5/5: account NETNSA_CURRENT_NSID in rtnl_net_get_size()

v1 -> v2:
  - patch 1/5: remove net from struct rtnl_net_dump_cb
  - patch 2/5: new in this version
  - patch 3/5: use a bool to know if rtnl_get_net_ns_capable() was called

====================
qed* enhancements series

The patch series add few enhancements to qed/qede drivers.

Changes from previous versions:
-------------------------------
v3: Revert v2 changes as the other paths (i.e. ptp) access the same data in
    atomic context.
v2: Use __set_bit()/__clear_bit() where data access doesn't need to be
    atomic.

f04e48dbfa qede: Update link status only when interface is ready.
In the case of internal reload (e.g., mtu change), there could be a race
between link-up notification from mfw and the driver unload processing. In
such case kernel assumes the link is up and starts using the queues which
leads to the server crash.

Send link notification to the kernel only when driver has already requested
MFW for the link.

149d3775f1 qede: Simplify the usage of qede-flags.
The values represented by qede->flags is being used in mixed ways:
  1. As 'value' at some places e.g., QEDE_FLAGS_IS_VF usage
  2. As bit-mask(value) at some places e.g., QEDE_FLAGS_PTP_TX_IN_PRORGESS
     usage.
This implementation pose problems in future when we want to add more flag
values e.g., overlap of the values, overflow of 64-bit storage.

Updated the implementation to go with approach (2) for qede->flags.

ec036eb92e qed: Display port_id in the UFP debug messages.
MFW sends UFP notifications mostly during the device init phase and PFs
might not be assigned with a name by this time. Hence capturing port-id in
the debug messages would help in finding which PF the ufp notification was
sent to.

Also, fixed a minor scemantic issue in a debug print.

Igor Russkikh says:

====================
Add support for Aquantia AQtion USB to 5/2.5GbE devices

This patchset introduces support for new multigig ethernet to USB dongle,
developed jointly by Aquantia (Phy) and ASIX (USB MAC).

The driver has similar structure with other ASIX MAC drivers (AX88179), but
with a number of important differences:
- Driver supports both direct Phy and custom firmware interface for Phy
  programming. This is due to different firmware modules available with
  this product.
- Driver handles new 2.5G/5G link speed configuration and reporting.
- Device support all speeds from 100M up to 5G.
- Device supports MTU up to 16K.

Device supports various standard networking features, like
checksum offloads, vlan tagging/filtering, TSO.

The code of this driver is based on original ASIX sources and was extended
by Aquantia for 5G multigig support.

Patchset v2 includes following changes:
- Function variables declarions fixed to reverse xmass tree
- Improve patch layout structure
- Remove unnecessary curly braces in switch/case statements
- Use 'packed' attribute for HW structures only
- Use eth_mac_addr function in set_mac_addr callback
- Remove unnecessary 'memset' calls.
- Read MAC address from EEPROM function has now better name
- Use driver_priv field to store context. It avoids ugly cast.
- Set max_mtu field. Remove check for MTU size
- Rewrite read/write functions. Add helpers for read/write 16/32 bit values
- Use mask and shifts instead of bitfields to support BE platforms.
- Use stack allocated buffer for configuring mcast filters
- Use AUTONEG_ENABLE when go to suspend state
- Pad out wol_cfg field from context structure. Use stack allocated instead
- Remove driver version
- Check field 'duplex' in set_link_ksetting callback as well
- Use already created defines in usb matching macro
- Rename phy_ops struct to phy_cfg
- Use ether_addr_copy for copying mac address
- Add fall-through comment in switch/case for avoid checkpatch warning
- Remove match for CDC ether device
- Add ASIX's HW id-s to match this driver
- Add all HW id-s with which driver can work to blacklist of cdc_ether driver

Patchset v3 includes following changes:
- Use linkmode_copy instead of bitmap_copy
- Remove Direct PHY access code since production HW will not have this
    mode anymore
- Fix line over 80 symbols and alignments in cdc_ether patch
- Add match for ECM configuration
    On start our HW reports both ECM and vendor configs.
    Linux prefers to use ECM driver and chooses active configuration
    which is for ecm driver (not for vendor specific).
    We need to match this configuration and forcibly switch configuration
    to vendor specific.

Patchset v4 includes following changes:
- Set gso_max_size.
- Optimize accessing to descriptors
- Use SKB_TRUESIZE macro.

0d32f17717 sctp: increase sk_wmem_alloc when head->truesize is increased
I changed to count sk_wmem_alloc by skb truesize instead of 1 to
fix the sk_wmem_alloc leak caused by later truesize's change in
xfrm in Commit 02968ccf01 ("sctp: count sk_wmem_alloc by skb
truesize in sctp_packet_transmit").

But I should have also increased sk_wmem_alloc when head->truesize
is increased in sctp_packet_gso_append() as xfrm does. Otherwise,
sctp gso packet will cause sk_wmem_alloc underflow.
