Clang is a little more pedantic than GCC, which does not warn when
falling through to a case that is just break or return. Clang's version
is more in line with the kernel's own stance in deprecated.rst, which
states that all switch/case blocks must end in either break,
fallthrough, continue, goto, or return. Add the missing break to silence
the warning.

Some devices have support for loading the PHY FW and in some cases this
can fail. When this fails, the FW will set the corresponding bit in the
link info structure. Also, the FW will send a link event if the correct
link event mask bit is set. Add support for printing an error message
when the PHY FW load fails during any link configuration flow and the
link event flow.
Since ice_check_module_power() is already doing something very similar
add a new function ice_check_link_cfg_err() so any failures reported in
the link info's link_cfg_err member can be printed in this one function.
Also, add the new ICE_FLAG_PHY_FW_LOAD_FAILED bit to the PF's flags so
we don't constantly print this error message during link polling if the
value never changed.

Part of virtchannel messages are treated in different way in switchdev
mode to block configuring VFs from iavf driver side. This blocking was
done by doing nothing and returning success, event without sending
response.
Not sending response for opcodes that aren't supported in switchdev mode
leads to block iavf driver message handling. This happens for example
when vlan is configured at VF config time (VLAN module is already
loaded).
To get rid of it ice driver should answer for each VF message. In
switchdev mode:
- for adding/deleting VLAN driver should answer success without doing
anything to allow creating vlan device on VFs
- for enabling/disabling VLAN stripping and promiscuous mode driver
should answer not supported, this feature in switchdev can be only
set from host side

Mostly reuse code from Geneve and VXLAN in TC parsing code. Add new GRE
header to match on correct fields. Create new dummy packets with GRE
fields.
Instead of checking if any encap values are presented in TC flower,
check if device is tunnel type or redirect is to tunnel device. This
will allow adding all combination of rules. For example filters only
with inner fields.
Return error in case device isn't tunnel but encap values are presented.
gre example:
- create tunnel device
ip l add $NVGRE_DEV type gretap remote $NVGRE_REM_IP local $VF1_IP \
dev $PF
- add tc filter (in switchdev mode)
tc filter add dev $NVGRE_DEV protocol ip parent ffff: flower dst_ip \

Parse tunnel specific fields from TC tool like outer MACs, outer IPs,
outer destination port and VNI. Save values and masks in outer header
struct and move header pointer to inner to simplify parsing inner

There are two cases for redirect action:
- from uplink to VF - TC filter is added on tunnel device
- from VF to uplink - TC filter is added on PR, for this case check if
redirect device is tunnel device
VXLAN example:
- create tunnel device
ip l add $VXLAN_DEV type vxlan id $VXLAN_VNI dstport $VXLAN_PORT \
dev $PF
- add TC filter (in switchdev mode)
tc filter add dev $VXLAN_DEV protocol ip parent ffff: flower \

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount

up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it go through appropriate helpers.
Even though the current code uses dev->addr_len the we can switch
to eth_hw_addr_set() instead of dev_addr_set(). The netdev is
always allocated by alloc_etherdev_mq() and there are at least two
places which assume Ethernet address:
- the line below calling eth_hw_addr_random()
- virtnet_set_mac_address() -> eth_commit_mac_addr_change()

CN10k SoCs use atomic stores of up to 128 bytes to submit
packets/instructions into co-processor cores. The enqueueing is performed
using Large Memory Transaction Store (LMTST) operations. They allow for

instructions to the same queue without needing to lock the queue or
synchronize their accesses.

While waiting for a carrier to come on one of the netdevices, some
devices will require to take the rtnl lock at some point to fully
initialize all parts of the link.
That's the case for SFP, where the rtnl is taken when a module gets
detected. This prevents mounting an NFS rootfs over an SFP link.
This means that while ipconfig waits for carriers to be detected, no SFP
modules can be detected in the meantime, it's only detected after
ipconfig times out.
This commit releases the rtnl_lock while waiting for the carrier to come
up, and re-takes it to check the for the init device and carrier status.

All the mptcp receive path is protected by the msk socket
spinlock. As consequences, the tx path has to play a few tricks to
allocate the forward memory without acquiring the spinlock multiple
times, making the overall TX path quite complex.
This patch tries to clean-up a bit the tx path, using completely
separated fwd memory allocation, for the rx and the tx path.
The forward memory allocated in the rx path is now accounted in
msk->rmem_fwd_alloc and is (still) protected by the msk socket spinlock.
To cope with the above we provide a few MPTCP-specific variants for
the helpers to charge, uncharge, reclaim and free the forward memory
in the receive path.
msk->sk_forward_alloc now accounts only the forward memory for the tx
path, we can use the plain core sock helper to manipulate it and drop
quite a bit of complexity.
On memory pressure, both rx and tx fwd memories are reclaimed.

There is a warning in xdp_rxq_info_unreg_mem_model() when reg_state isn't
equal to REG_STATE_REGISTERED, so the warning in xdp_rxq_info_unreg() is
redundant.

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look

the writes to it go through appropriate helpers.

Use the new of_get_ethdev_address() helper for the cases
where dev->dev_addr is passed in directly as the destination.
