Similar to native xdp, do not always linearize the skb in
netif_receive_generic_xdp routine but create a non-linear xdp_buff to be
processed by the eBPF program. This allow to add multi-buffer support

Set scope automatically in ip_route_output_ports() (using the socket
SOCK_LOCALROUTE flag). This way, callers don't have to overload the
tos with the RTO_ONLINK flag, like RT_CONN_FLAGS() does.
For callers that don't pass a struct sock, this doesn't change anything
as the scope is still set to RT_SCOPE_UNIVERSE when sk is NULL.
Callers that passed a struct sock and used RT_CONN_FLAGS(sk) or
RT_CONN_FLAGS_TOS(sk, tos) for the tos are modified to use
ip_sock_tos(sk) and RT_TOS(tos) respectively, as overloading tos with
the RTO_ONLINK flag now becomes unnecessary.
In drivers/net/amt.c, all ip_route_output_ports() calls use a 0 tos
parameter, ignoring the SOCK_LOCALROUTE flag of the socket. But the sk
parameter is a kernel socket, which doesn't have any configuration path
for setting SOCK_LOCALROUTE anyway. Therefore, ip_route_output_ports()
will continue to initialise scope with RT_SCOPE_UNIVERSE and amt.c
doesn't need to be modified.
Also, remove RT_CONN_FLAGS() and RT_CONN_FLAGS_TOS() from route.h as
these macros are now unused.
The objective is to eventually remove RTO_ONLINK entirely to allow
converting ->flowi4_tos to dscp_t. This will ensure proper isolation
between the DSCP and ECN bits, thus minimising the risk of introducing
bugs where TOS values interfere with ECN.

====================
net: dsa: realtek: variants to drivers, interfaces to a common module
The current driver consists of two interface modules (SMI and MDIO) and
two family/variant modules (RTL8365MB and RTL8366RB). The SMI and MDIO
modules serve as the platform and MDIO drivers, respectively, calling
functions from the variant modules. In this setup, one interface module
can be loaded independently of the other, but both variants must be
loaded (if not disabled at build time) for any type of interface. This
approach doesn't scale well, especially with the addition of more switch
variants (e.g., RTL8366B), leading to loaded but unused modules.
Additionally, this also seems upside down, as the specific driver code
normally depends on the more generic functions and not the other way
around.
Each variant module was converted into real drivers, serving as both a
platform driver (for switches connected using the SMI interface) and an
MDIO driver (for MDIO-connected switches). The relationship between the
variant and interface modules is reversed, with the variant module now
calling both interface functions (if not disabled at build time). While
in most devices only one interface is likely used, the interface code is
significantly smaller than a variant module, consuming fewer resources
than the previous code. With variant modules now functioning as real
drivers, compatible strings are published only in a single variant
module, preventing conflicts.
The patch series introduces a new common module for functions shared by
both variants. This module also absorbs the two previous interface
modules, as they would always be loaded anyway.
The series relocates the user MII driver from realtek-smi to rtl83xx. It
is now used by MDIO-connected switches instead of the generic DSA
driver. There's a change in how this driver locates the MDIO node. It
now only searches for a child node named "mdio".
The dsa_switch in realtek_priv->ds is now embedded in the struct. It is
always in use and avoids dynamic memory allocation.
Testing has been performed with an RTL8367S (rtl8365mb) using MDIO
interface and an RTL8366RB (rtl8366) with SMI interface.
