This patchset carry forwards the work initiated in [1] and discussion
futher concluded at [2].
To improve visibility of representor netdevice, its association with
PF or VF, physical port, two new devlink port flavours are added as
PCI PF and PCI VF ports.
A sample eswitch view can be seen below,
Register devlink port of physical port, PCI PF and PCI VF flavour
for each PF, VF when a given devlink instance is in switchdev mode.
Implement ndo_get_devlink_port callback API to make use of registered
devlink ports.
This eliminates ndo_get_phys_port_name() and ndo_get_port_parent_id()
callbacks
In an eswitch, PCI VF may have port which is normally represented using
a representor netdevice.
To have better visibility of eswitch port, its association with VF,
and its representor netdevice, introduce a PCI VF port flavour.
When devlink port flavour is PCI VF, fill up PCI VF attributes of

I agree that is confusing, that is why I don't like the 'xxx' naming
convention in general, found in man

Add a new "bpftool prog run" subcommand to run a loaded program on input
data (and possibly with input context) passed by the user.
Print output data (and output context if relevant) into a file or into
the console. Print return value and duration for the test run into the
console.

When we changed the device and CPU maps to use linked lists instead of
bitmaps, we also removed the need for the map_insert_ctx() helpers to keep
track of the bitmaps inside each map. However, it seems I forgot to remove
the function definitions stubs, so remove those
From: Toke Høiland-Jørgensen
The subsequent patch to add a new devmap sub-type can re-use much of the
initialisation and allocation code, so refactor it into separate functions.

This series adds a new map type, devmap_hash, that works like the existing
devmap type, but using a hash-based indexing scheme. This is useful for the use
case where a devmap is indexed by ifindex (for instance for use with the routing
table lookup helper). For this use case, the regular devmap nee
From: Toke Høiland-Jørgensen
A common pattern when using xdp_redirect_map() is to create a device map
where the lookup key is simply ifindex. Because device maps are arrays,
this leaves holes in the map, and the map has to be sized to fit the
largest ifindex, regardless of how many devices actual

socket->wq is assign-once, set when we are initializing both
struct socket it's in and struct socket_wq it points to. As the
matter of fact, the only reason for separate allocation was the
ability to RCU-delay freeing of socket_wq. RCU-delaying the
freeing of socket itself gets rid of that need,
we do have an RCU-delayed part there already (freeing the wq),
so it's not like the pipe situation; moreover, it might be
worth considering coallocating wq with the rest of struct sock_alloc.
->sk_wq in struct sock would remain a pointer as it is, but
the object it normally points to would be coall
