Ilya Lipnitskiy 4732315ca9 net: dsa: mt7530: clean up core and TRGMII clock setup
Three minor changes:

- When disabling PLL, there is no need to call core_write_mmd_indirect
  directly, use the core_write wrapper instead like the rest of the code
  in the function does. This change helps with consistency and
  readability. Move the comment to the definition of
  core_read_mmd_indirect where it belongs.

- Disable both core and TRGMII Tx clocks prior to reconfiguring.
  Previously, only the core clock was disabled, but not TRGMII Tx clock.
  So disable both, then configure them, then re-enable both, for
  consistency.

- The core clock enable bit (REG_GSWCK_EN) is written redundantly three
  times. Simplify the code and only write the register only once at the
  end of clock reconfiguration to enable both core and TRGMII Tx clocks.

Tested on Ubiquiti ER-X running the GMAC0 and MT7530 in TRGMII mode.

Petr Machata de1d1ee3e3 nexthop: Rename artifacts related to legacy multipath nexthop groups
After resilient next-hop groups have been added recently, there are two
types of multipath next-hop groups: the legacy "mpath", and the new
"resilient". Calling the legacy next-hop group type "mpath" is unfortunate,
because that describes the fact that a packet could be forwarded in one of
several paths, which is also true for the resilient next-hop groups.

Therefore, to make the naming clearer, rename various artifacts to reflect
the assumptions made. Therefore as of this patch:

- The flag for multipath groups is nh_grp_entry::is_multipath. This
  includes the legacy and resilient groups, as well as any future group
  types that behave as multipath groups.
  Functions that assume this have "mpath" in the name.

- The flag for legacy multipath groups is nh_grp_entry::hash_threshold.
  Functions that assume this have "hthr" in the name.

- The flag for resilient groups is nh_grp_entry::resilient.
  Functions that assume this have "res" in the name.

Besides the above, struct nh_grp_entry::mpath was renamed to ::hthr as
well.

UAPI artifacts were obviously left intact.

Alexei Starovoitov fddbf4b6dc Merge branch 'bpf: Support calling kernel function'
Martin KaFai says:

====================

This series adds support to allow bpf program calling kernel function.

The use case included in this set is to allow bpf-tcp-cc to directly
call some tcp-cc helper functions (e.g. "tcp_cong_avoid_ai()").  Those
functions have already been used by some kernel tcp-cc implementations.

This set will also allow the bpf-tcp-cc program to directly call the
kernel tcp-cc implementation,  For example, a bpf_dctcp may only want to
implement its own dctcp_cwnd_event() and reuse other dctcp_*() directly
from the kernel tcp_dctcp.c instead of reimplementing (or
copy-and-pasting) them.

The tcp-cc kernel functions mentioned above will be white listed
for the struct_ops bpf-tcp-cc programs to use in a later patch.
The white listed functions are not bounded to a fixed ABI contract.
Those functions have already been used by the existing kernel tcp-cc.
If any of them has changed, both in-tree and out-of-tree kernel tcp-cc
implementations have to be changed.  The same goes for the struct_ops
bpf-tcp-cc programs which have to be adjusted accordingly.

Please see individual patch for details.

v2:
- Patch 2 in v1 is removed.  No need to support extern func in kernel.
  Changed libbpf to adjust the .ksyms datasec for extern func
  in patch 11. (Andrii)
- Name change: btf_check_func_arg_match() and btf_check_subprog_arg_match()
  in patch 2. (Andrii)
- Always set unreliable on any error in patch 2 since it does not
  matter. (Andrii)
- s/kern_func/kfunc/ and s/descriptor/desc/ in this set. (Andrii)
- Remove some unnecessary changes in disasm.h and disasm.c
  in patch 3.  In particular, no need to change the function
  signature in bpf_insn_revmap_call_t.  Also, removed the changes
  in print_bpf_insn().
- Fixed an issue in check_kfunc_call() when the calling kernel function
  returns a pointer in patch 3.  Added a selftest.
- Adjusted the verifier selftests due to the changes in the verifier log
  in patch 3.
- Fixed a comparison issue in kfunc_desc_cmp_by_imm() in patch 3. (Andrii)
- Name change: is_ldimm64_insn(),
  new helper: is_call_insn() in patch 10 (Andrii)
- Move btf_func_linkage() from btf.h to libbpf.c in patch 11. (Andrii)
- Fixed the linker error when CONFIG_BPF_SYSCALL is not defined.
  Moved the check_kfunc_call from filter.c to test_run.c in patch 14.

Martin KaFai Lau 7bd1590d4e bpf: selftests: Add kfunc_call test
This patch adds a few kernel function bpf_kfunc_call_test*() for the
selftest's test_run purpose.  They will be allowed for tc_cls prog.

The selftest calling the kernel function bpf_kfunc_call_test*()
is also added in this patch.

Martin KaFai Lau 78e60bbbe8 bpf: selftests: Bpf_cubic and bpf_dctcp calling kernel functions
This patch removes the bpf implementation of tcp_slow_start()
and tcp_cong_avoid_ai().  Instead, it directly uses the kernel
implementation.

It also replaces the bpf_cubic_undo_cwnd implementation by directly
calling tcp_reno_undo_cwnd().  bpf_dctcp also directly calls
tcp_reno_cong_avoid() instead.
