This change makes sure to sort the existing minimal kernel configuration
containing options required for running BPF selftests alphabetically.
Doing so will make it easier to diff it against other configurations,
which in turn helps with maintaining disjunct config files that build on
top of each other. It also helped identify the CONFIG_IPV6_GRE being set
twice and removes one of the occurrences.
Lastly, we change NET_CLS_BPF from 'm' to 'y'. Having this option as 'm'
will cause failures of the btf_skc_cls_ingress selftest.

The previous commit fixed a bug in the bpf_skb_set_tunnel_key helper to
avoid dropping packets whose outer source IP address isn't assigned to a
host interface. This commit changes the corresponding selftest to not
assign the outer source IP address to an interface.
Not assigning the source IP to an interface causes two issues in the
existing test:
1. The ARP requests will fail for that IP address so we need to add the
ARP entry manually.
2. The encapsulated ICMP echo reply traffic will not reach the VXLAN
device. It will be dropped by the stack before, because the
outer destination IP is unknown.
To solve 2., we have two choices. Either we perform decapsulation
ourselves in a BPF program attached at veth1 (the base device for the
VXLAN device), or we switch the outer destination address when we
receive the packet at veth1, such that the stack properly demultiplexes
it to the VXLAN device afterward.
This commit implements the second approach, where we switch the outer
destination address from the unassigned IP address to the assigned one,
only for VXLAN traffic ingressing veth1.
Then, at the vxlan device, the BPF program that checks the output of
bpf_skb_get_tunnel_key needs to be updated as the expected local IP
address is now the unassigned one.

Commit 26101f5ab6bd ("bpf: Add source ip in "struct bpf_tunnel_key"")
added support for getting and setting the outer source IP of encapsulated
packets via the bpf_skb_{get,set}_tunnel_key BPF helper. This change
allows BPF programs to set any IP address as the source, including for
example the IP address of a container running on the same host.
In that last case, however, the encapsulated packets are dropped when
looking up the route because the source IP address isn't assigned to any
interface on the host. To avoid this, we need to set the
FLOWI_FLAG_ANYSRC flag.

Add MTU change with stmmac interface running
This series is to permit MTU change while the interface is running.
Major rework are needed to permit to allocate a new dma conf based on
the new MTU before applying it. This is to make sure there is enough
space to allocate all the DMA queue before releasing the stmmac driver.
This was tested with a simple way to stress the network while the
interface is running.
2 ssh connection to the device:
- One generating simple traffic with while true; do free; done
- The other making the mtu change with a delay of 1 second
The connection is correctly stopped and recovered after the MTU is changed.
The first 2 patch of this series are minor fixup that fix problems
presented while testing this. One fix a problem when we renable a queue
while we are generating a new dma conf. The other is a corner case that
was notice while stressing the driver and turning down the interface while
there was some traffic.
(this is a follow-up of a simpler patch that wanted to add the same
feature. It was suggested to first try to check if it was possible to
apply the new configuration. Posting as RFC as it does major rework for
the new concept of DMA conf)

As lately recommended in the mailing list[1], set the clock to zero time as
part of initialization.
The idea is that when the clock reads 'Jan 1, 1970', then it is clearly
wrong and user will not mistakenly think that the clock is set correctly.
If as part of initialization, the driver sets the clock, user might see
correct date and time (maybe with a small shift) and assume that there
is no need to sync the clock.
Fix the existing code of Spectrum-1 to set the 'timecounter' to zero.

If ingress correction is set on a port for a given packet type, then

If egress correction is set on a port for a given packet type, then when
such a packet is transmitted via the port, the current time stamp is

On Versal TSU clock cannot be disabled irrespective of whether PTP is
used. Hence introduce a new Versal config structure with a "need tsu"
caps flag and check the same in runtime_suspend/resume before cutting
off clocks.
More information on this for future reference:
This is an IP limitation on versions 1p11 and 1p12 when Qbv is enabled
(See designcfg1, bit 3). However it is better to rely on an SoC specific
check rather than the IP version because tsu clk property itself may not
represent actual HW tsu clock on some chip designs.

mtk_eth_soc: add xdp support
Introduce XDP support for mtk_eth_soc driver if rx hwlro is not
enabled in the chipset (e.g. mt7986).
Supported XDP verdicts:
- XDP_PASS
- XDP_DROP
- XDP_REDIRECT
- XDP_TX
- ndo_xdp_xmit
Rely on page_pool allocator for single page buffers in order to keep
them dma mapped and add skb recycling support.
Changes since v3:
- add missing rcu_read_lock()/rcu_read_unlock()
- introduce mtk_page_pool_enabled() utility routine
Changes since v2:
- fix leftover sparse warning
- add page_pool ethtool stats
Changes since v1:
- do not allocate mtk_xdp_stats array on the stack in mtk_rx_poll
- add rcu annotation to bpf program
