IPPROTO_IP (0) is not valid for raw sockets. Default the protocol for
raw sockets to IPPROTO_RAW if the protocol has not been set via the -P
option.

This driver makes use of devm_mdiobus_alloc_size. To ensure this is
available select MDIO_DEVRES which provides it.

When IPV6_SEG6_HMAC is enabled and CRYPTO is disabled, it results in the
following Kbuild warning:
WARNING: unmet direct dependencies detected for CRYPTO_HMAC

The local_storage->list will be traversed by rcu reader in parallel.
Thus, hlist_add_head_rcu() is needed in bpf_selem_link_storage_nolock().
This patch fixes it.
This part of the code has recently been refactored in bpf-next
and this patch makes changes to the new file "bpf_local_storage.c".

The sk_storage->list will be traversed by rcu reader in parallel.
Thus, hlist_add_head_rcu() is needed in __selem_link_sk(). This
patch fixes it.
This part of the code has recently been refactored in bpf-next.
A separate fix will be provided for the bpf-next tree.
Fixes: 6ac99e8f23d4 ("bpf: Intr
Hi Dave, Jakub,
Similar to PCI VF, PCI SF represents portion of the device.
PCI SF is represented using a new devlink port flavour.
This short series implements small part of the RFC described in detail at [1]
and [2].
It extends
(a) devlink core to expose new devlink port flavour 'pcisf'.
(b)
Extended devlink interface for the user to add and delete port.
Extend devlink to connect user requests to driver to add/delete
such port in the device.
When driver routines are invoked, devlink instance lock is not held.
This enables driver to perform several devlink objects registration,
unregis
A PCI sub-function (SF) represents a portion of the device similar
to PCI VF.
In an eswitch, PCI SF may have port which is normally represented
using a representor netdevice.
To have better visibility of eswitch port, its association with SF,
and its representor netdevice, introduce a PCI SF port
Simulate PCI SF ports. Allow user to create one or more PCI SF ports.
Examples:
Create a PCI PF and PCI SF port.
$ devlink port add netdevsim/netdevsim10/10 flavour pcipf pfnum 0
$ devlink port add netdevsim/netdevsim10/11 flavour pcisf pfnum 0 sfnum 44
$ devlink port show netdevsim/netdevsim10/1
Simulate PCI PF ports. Allow user to create one or more PCI PF ports.
Examples:
Create a device with ID=10 and one physical port.
$ echo "10 1" > /sys/bus/netdevsim/new_device
Add and show devlink port of flavour 'pcipf' for PF number 0.
$ devlink port add netdevsim/netdevsim10/10 flavour pcipf
Allow users to get/set hardware address for the PCI port.
Below example creates one devlink port, queries a port, sets a
hardware address.
Example of a PCI SF port which supports a port function hw_addr set:
Create a device with ID=10 and one physical port.
$ echo "10 1" > /sys/bus/netdevsim/new_
devlink port function can be in active or inactive state.
Allow users to get and set port function's state.
Example of a PCI SF port which supports a port function:
Create a device with ID=10 and one physical port.
$ echo "10 1" > /sys/bus/netdevsim/new_device
$ devlink port show
netdevsim/netdevs
Simulate port function state of a PCI port.
This enables users to get and set the state of the PCI port function.
Example of a PCI SF port which supports a port function:
Create a device with ID=10 and one physical port.
$ echo "10 1" > /sys/bus/netdevsim/new_device
$ devlink port add netdevsim/n
