The driver is designed to drop Rx packets and reclaim the buffers
when an allocation fails, and the network interface needs to safely
handle this packet loss. Therefore, an allocation failure of Rx
SKBs is relatively benign.
However, the output of the warning message occurs with a high
scheduling priority that can cause excessive jitter/latency for
other high priority processing.
This commit suppresses the warning messages to prevent scheduling
problems while retaining the failure count in the statistics of
the network interface.

When a macsec interface is created, the mtu is calculated with the lower
interface's mtu value.
If the mtu of lower interface is lower than the length, which is needed
by macsec interface, macsec's mtu value will be overflowed.
So, if the lower interface's mtu is too low, macsec interface's mtu
should be set to 0.
Test commands:
ip link add dummy0 mtu 10 type dummy
ip link add macsec0 link dummy0 type macsec
ip link show macsec0
Before:
11: macsec0@dummy0: <BROADCAST,MULTICAST,M-DOWN> mtu 4294967274

When fixing the initialization race, we neglected to account for
the fact that debugfs is initialized in wiphy_register(), and
some debugfs things went missing (or rather were rerooted to the
global debugfs root).
Fix this by adding debugfs entries only after wiphy_register().
This requires some changes in the rate control code since it
currently adds debugfs at alloc time, which can no longer be
done after the reordering.

When x25_lapb_receive_frame() returns, local variable "nb" becomes

Since we do not clear all the mptcp sock RX options in a

That would lead to mapping data corruption and will trigger

These patches are related to the scenario described in commit

and we've closed our one-to-one socket, while the peer crashes without
being detected, restarts and reconnects using the same addresses and
ports, we start association shutdown.
In this case, Cumulative TSN Ack in the SHUTDOWN that we send has

When we start shutdown in sctp_sf_do_dupcook_a(), we want to bundle

commit 4ff40b86262b ("sctp: set chunk transport correctly when it's a

the SHUTDOWN.
Fix this by passing a reference to the COOKIE-ACK chunk as an argument
to sctp_sf_do_9_2_start_shutdown() and onward to
sctp_make_shutdown(). This way the SHUTDOWN chunk is assigned the same
transport as the COOKIE-ACK chunk, which allows them to be bundled.
In sctp_sf_do_9_2_start_shutdown(), the void *arg parameter was
previously unused. Now that we're taking it into use, it must be a
valid pointer to a chunk, or NULL. There is only one call site where
it's not, in sctp_sf_autoclose_timer_expire(). Fix that too.

net: dsa: b53: Various ARL fixes
This patch series fixes a number of short comings in the existing b53
driver ARL management logic in particular:
- we were not looking up the {MAC,VID} tuples against their VID, despite
having VLANs enabled
- the MDB entries (multicast) would lose their validity as soon as a
single port in the vector would leave the entry
- the ARL was currently under utilized because we would always place new
entries in bin index #1, instead of using all possible bins available,
thus reducing the ARL effective size by 50% or 75% depending on the
switch generation
- it was possible to overwrite the ARL entries because no proper space
verification was done
This patch series addresses all of these issues.
Changes in v2:
- added a new patch to correctly flip invidual VLAN learning vs. shared
VLAN learning depending on the global VLAN state
- added Andrew's R-b tags for patches which did not change
- corrected some verbosity and minor issues in patch #4 to match caller

net: Fix looping with vrf, xfrms and qdisc on VRF
Trev reported that use of VRFs with xfrms is looping when a qdisc
is added to the VRF device. The combination of xfrm + qdisc is not
handled by the VRF driver which lost track that it has already
seen the packet.
The XFRM_TRANSFORMED flag is used by the netfilter code for a similar
purpose, so re-use for VRF. Patch 1 drops the #ifdef around setting
the flag in the xfrm output functions. Patch 2 adds a check to
the VRF driver for flag; if set the packet has already passed through
the VRF driver once and does not need to recirculated a second time.
This is a day 1 bug with VRFs; stable wise, I would only take this
back to 4.14. I have a set of test cases which I will submit to

This patch is to enable Intel SERDES power up/down sequence. The SERDES
converts 8/10 bits data to SGMII signal. Below is an example of
HW configuration for SGMII mode. The SERDES is located in the PHY IF
in the diagram below.
<-----------------GBE Controller---------->|<--External PHY chip-->
+----------+ +----+ +---+ +----------+
| EQoS | <-GMII->| DW | < ------ > |PHY| <-SGMII-> | External |
| MAC | |xPCS| |IF | | PHY |
+----------+ +----+ +---+ +----------+
^ ^ ^ ^

+---------------------MDIO-------------------------+
PHY IF configuration and status registers are accessible through
mdio address 0x15 which is defined as mdio_adhoc_addr. During D0,
The driver will need to power up PHY IF by changing the power state
to P0. Likewise, for D3, the driver sets PHY IF power state to P3.

Use the function devm_platform_ioremap_resource_byname() to simplify
source code which calls the functions platform_get_resource_byname()
and devm_ioremap_resource(). Remove also a few error messages which
became unnecessary with this software refactoring.
