1edb5cbf49 Revert "net-loopback: set lo dev initial state to UP"
In commit c9dca822c7 ("net-loopback: set lo dev initial state to UP"),
linux started automatically bringing up the loopback device of a newly
created namespace. However, an existing user script might reasonably have
the following stanza when creating a new namespace -- and in fact at least
tools/testing/selftests/net/fib_nexthops.sh in Linux's very own testsuite
does:

 # set -e
 # ip netns add foo
 # ip -netns foo addr add 127.0.0.1/8 dev lo
 # ip -netns foo link set lo up
 # set +e

This will now fail, because the kernel reasonably rejects "ip addr add" of
a duplicate address. The described change of behavior therefore constitutes
a breakage. Revert it.

4217a64e18 net: phy: introduce phydev->port
At the moment, PORT_MII is reported in the ethtool ops. This is odd
because it is an interface between the MAC and the PHY and no external
port. Some network card drivers will overwrite the port to twisted pair
or fiber, though. Even worse, the MDI/MDIX setting is only used by
ethtool if the port is twisted pair.

Set the port to PORT_TP by default because most PHY drivers are copper
ones. If there is fibre support and it is enabled, the PHY driver will
set it to PORT_FIBRE.

This will change reporting PORT_MII to either PORT_TP or PORT_FIBRE;
except for the genphy fallback driver.

(only one Traffic Class). At the same time, it allows a software based
LLDP agent - userspace application i.e. lldpad) to receive DCB TLVs
and set desired DCB configuration through DCB related netlink callbacks.

handlers for configuring link parameters like speed/duplex and autoneg etc.
Patche 6&7 registers driver callbacks for physical link configuration.

Change-log:
v2:
	- Fixed review comments
	- Corrected indentation issues
        - Return -ENOMEM incase of mbox allocation failure
	- added validation for input fecparams bitmask values
        - added more comments

1fb3ca7675 net: octeontx2: Fix the confusion in buffer alloc failure path
Pavel pointed that the return of dma_addr_t in
otx2_alloc_rbuf/__otx2_alloc_rbuf() seem suspicious because a negative
error code may be returned in some cases. For a dma_addr_t, the error
code such as -ENOMEM does seem a valid value, so we can't judge if the
buffer allocation fail or not based on that value. Add a parameter for
otx2_alloc_rbuf/__otx2_alloc_rbuf() to store the dma address and make
the return value to indicate if the buffer allocation really fail or
not.

163c5e6262 net: mhi: Add mbim proto
MBIM has initially been specified by USB-IF for transporting data (IP)
between a modem and a host over USB. However some modern modems also
support MBIM over PCIe (via MHI). In the same way as QMAP(rmnet), it
allows to aggregate IP packets and to perform context multiplexing.

This change adds minimal MBIM data transport support to MHI, allowing
to support MBIM only modems. MBIM being based on USB NCM, it reuses
and copy some helpers/functions from the USB stack (cdc-ncm, cdc-mbim).

Note that is a subset of the CDC-MBIM specification, supporting only
transport of network data (IP), there is no support for DSS. Moreover
the multi-session (for multi-pdn) is not supported in this initial
version, but will be added latter, and aligned with the cdc-mbim
solution (VLAN tags).

This code has been inspired from the mhi_mbim downstream implementation
(Carl Yin <carl.yin@quectel.com>).

ddeb9bfa59 net: mhi: Add protocol support
MHI can transport different protocols, some are handled at upper level,
like IP and QMAP(rmnet/netlink), but others will need to be inside MHI
net driver, like mbim. This change adds support for protocol rx and
tx_fixup callbacks registration, that can be used to encode/decode the
targeted protocol.

a9219b332f i40e: VLAN field for flow director
Allow user to specify VLAN field and add it to flow director. Show VLAN
field in "ethtool -n ethx" command.
Handle VLAN type and tag field provided by ethtool command. Refactored
filter addition, by replacing static arrays with runtime dummy packet
creation, which allows specifying VLAN field.
Previously, VLAN field was omitted.

efca91e89b i40e: Add flow director support for IPv6
Flow director for IPv6 is not supported.
1) Implementation of support for IPv6 flow director.
2) Added handlers for addition of TCP6, UDP6, SCTP6, IPv6.
3) Refactored legacy code to make it more generic.
4) Added packet templates for TCP6, UDP6, SCTP6, IPv6.
5) Added handling of IPv6 source and destination address for flow director.
6) Improved argument passing for source and destination portin TCP6, UDP6
   and SCTP6.
7) Added handling of ethtool -n for IPv6, TCP6,UDP6, SCTP6.
8) Used correct bit flag regarding FLEXOFF field of flow director data
   descriptor.

Without this patch, there would be no support for flow director on IPv6,
TCP6, UDP6, SCTP6.
Tested based on x710 datasheet by using:
ethtool -N enp133s0f0 flow-type tcp4 src-port 13 dst-port 37 user-def 0x44142 action 1
ethtool -N enp133s0f0 flow-type tcp6 src-port 13 dst-port 40 user-def 0x44142 action 2
ethtool -N enp133s0f0 flow-type udp4 src-port 20 dst-port 40 user-def 0x44142 action 3
ethtool -N enp133s0f0 flow-type udp6 src-port 25 dst-port 40 user-def 0x44142 action 4
ethtool -N enp133s0f0 flow-type sctp4 src-port 55 dst-port 65 user-def 0x44142 action 5
ethtool -N enp133s0f0 flow-type sctp6 src-port 60 dst-port 40 user-def 0x44142 action 6
ethtool -N enp133s0f0 flow-type ip4 src-ip 1.1.1.1 dst-ip 1.1.1.4 user-def 0x44142 action 7
ethtool -N enp133s0f0 flow-type ip6 src-ip fe80::3efd:feff:fe6f:bbbb dst-ip fe80::3efd:feff:fe6f:aaaa user-def 0x44142 action 8
Then send traffic from client which matches the criteria provided to ethtool.
Observe that packets are redirected to user set queues with ethtool -S <interface>

("disable-fw-lldp on"). The driver initialized DCB functionality with
default values, one traffic class with 100% bandwidth allocated.

LLDP agent is turned off, in case of driver probe and device
reset on reconfiguration.

Update copyright dates as appropriate.

Software based DCB is a brand-new feature in i40e driver.
Before, DCB was implemented by Firmware LLDP agent only. The agent was
responsible for handling incoming DCB-related LLDP frames and
applying received DCB configuration to hardware.
