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

The current code allows for VXLAN and GENEVE to inherit the TOS
respective the TTL when skb-protocol is ETH_P_IP or ETH_P_IPV6.
However when the payload is VLAN encapsulated, then this inheriting
does not work, because the visible skb-protocol is of type
ETH_P_8021Q or ETH_P_8021AD.

Instead of skb->protocol use skb_protocol().

net: usb: ax88179_178a: improvements and bug fixes

Power management was partially broken. There were two issues when dropping

1. Resume was not doing a fully HW restore. Only a partial restore. This
lead to a couple things being broken on resume. One of them being tcp rx.
2. wolopt was not being restored properly on resume.

Also did some general improvements and clean up to make it easier to fix

Simplify the logic that selects bpf_prog_pack_size, and always use
(PMD_SIZE * num_possible_nodes()). This is a good tradeoff, as most of
the performance benefit observed is from less direct map fragmentation [0].

Also, module_alloc(4MB) may not allocate 4MB aligned memory. Therefore,
we cannot use (ptr & bpf_prog_pack_mask) to find the correct address of
bpf_prog_pack. Fix this by checking the header address falls in the range
of pack->ptr and (pack->ptr + bpf_prog_pack_size).

When tracing a function with IPMODIFY ftrace_ops (livepatch), the bpf
trampoline must follow the instruction pointer saved on stack. This needs
extra handling for bpf trampolines with BPF_TRAMP_F_CALL_ORIG flag.

Implement bpf_tramp_ftrace_ops_func and use it for the ftrace_ops used
by BPF trampoline. This enables tracing functions with livepatch.

This also requires moving bpf trampoline to *_ftrace_direct_mult APIs.

Currently we call the original function by using the absolute address
given at the JIT generation. That's not usable when having trampoline
attached to multiple functions, or the target address changes dynamically
(in case of live patch). In such cases we need to take the return address
from the stack.

Adding support to retrieve the original function address from the stack
by adding new BPF_TRAMP_F_ORIG_STACK flag for arch_prepare_bpf_trampoline
function.

Basically we take the return address of the 'fentry' call:

   function + 0: call fentry    # stores 'function + 5' address on stack
   function + 5: ...

The 'function + 5' address will be used as the address for the
original function to call.

IPMODIFY (livepatch) and DIRECT (bpf trampoline) ops are both important
users of ftrace. It is necessary to allow them work on the same function
at the same time.

First, DIRECT ops no longer specify IPMODIFY flag. Instead, DIRECT flag is
handled together with IPMODIFY flag in __ftrace_hash_update_ipmodify().

Then, a callback function, ops_func, is added to ftrace_ops. This is used
by ftrace core code to understand whether the DIRECT ops can share with an
IPMODIFY ops. To share with IPMODIFY ops, the DIRECT ops need to implement
the callback function and adjust the direct trampoline accordingly.

If DIRECT ops is attached before the IPMODIFY ops, ftrace core code calls
ENABLE_SHARE_IPMODIFY_PEER on the DIRECT ops before registering the
IPMODIFY ops.

If IPMODIFY ops is attached before the DIRECT ops, ftrace core code calls
ENABLE_SHARE_IPMODIFY_SELF in __ftrace_hash_update_ipmodify. Owner of the
DIRECT ops may return 0 if the DIRECT trampoline can share with IPMODIFY,
so error code otherwise. The error code is propagated to
register_ftrace_direct_multi so that onwer of the DIRECT trampoline can
handle it properly.

For more details, please refer to comment before enum ftrace_ops_cmd.
