IPoIB netlink support and mlx5e pre-allocated netdevice initialization
IP link was broken due to the changes in IPoIB for the rdma_netdev
support after commit cd565b4b51
("IB/IPoIB: Support acceleration options callbacks").
This patchset fixes IPoIB pkey creation and removal using rtnetlink by
adding support in both IPoIB ULP layer and mlx5 layer:
From Jason and Denis:
1) Introduces changes in the RDMA netdev code in order to
allow allocation of the netdev to be done by the rtnl netdev code.
2) Reworks IPoIB initialization to use the two step rdma_netdev
creation.
From Feras and Saeed, mlx5e netdev layer refactoring to allow accepting
pre-allocated netdevs:
3) Adds support to initialize/cleanup netdevs that are not created
by mlx5 driver.
4) Change mlx5e netdevice layer to accept the pre-allocated netdevice
queue number.
5) Initialize mlx5e generic structures in one place to be used for all
netdevs types NIC/representors/IPoIB (both mlx5 allocated and
pre-allocted).

It has been reported that since
commit 05212ba813 ("r8169: set RxConfig after tx/rx is enabled for RTL8169sb/8110sb devices")
at least RTL_GIGA_MAC_VER_38 NICs work erratically after a resume from
suspend.
The problem has been traced to a missing RX_MULTI_EN bit in the RxConfig
register.
We already set this bit for RTL_GIGA_MAC_VER_35 NICs of the same 8168F
chip family so let's do it also for its other siblings: RTL_GIGA_MAC_VER_36
and RTL_GIGA_MAC_VER_38.
Curiously, the NIC seems to work fine after a system boot without having
this bit set as long as the system isn't suspended and resumed.

During boot, mlx4_core sets the driverinit configuration parameters and
updates the devlink module on the initial values calling
devlink_param_driverinit_value_set().
If devlink_param_driverinit_value_set() returns an error mlx4_core
reports kernel module warning.
This caused false alarm during boot in case kernel was compiled with
CONFIG_NET_DEVLINK off.
Fix by removing warning reported in case
devlink_param_driverinit_value_set() fails.
This actually makes the function mlx4_devlink_set_init_value()
redundant to using directly devlink_param_driverinit_value_set() and so
removed.
It fixes the following kernel trace:
mlx4_core 0000:00:06.0: devlink set parameter 0 value failed (err = -95)

The DECAP_ECN0 trap will be used to trap packets where the overlay
packet is marked with Non-ECT, but the underlay packet is marked with
either ECT(0), ECT(1) or CE. When trapped, such packets will be counted
as errors by the VxLAN driver and thus provide better visibility.
The NVE_ENCAP_ARP trap will be used to trap ARP packets undergoing NVE
encapsulation. This is needed in order to support E-VPN ARP suppression,
where the Linux bridge does not flood ARP packets through tunnel ports
in case it can answer the ARP request itself.
Note that all the packets trapped via these traps are marked with
'offload_fwd_mark', so as to not be re-flooded by the Linux bridge
through the ASIC ports.

The current design of mlx5e driver ignores the netdevice TX/RX queues
number for netdevices that RDMA IPoIB ULP creates. Instead, the queue
number is initialized to the maximum number that mlx5 thinks best for
performance. As a result, ULP drivers that choose to create a netdevice
with queue number that is less than the maximum channels mlx5 creates,
will get a memory corruption.
This fix changes the mlx5e netdev logic to respect ULP netdevices TX/RX
queue number and use it when creating resources instead of the maximum

CGX LMAC link status change events from firmware
and managing them. Processing part will be added
in followup patches.
- Introduced eventqueue for posting events from cgx lmac.
Queueing mechanism will ensure that events can be posted
and firmware can be acked immediately and hence event
reception and processing are decoupled.
- Events gets added to the queue by notification callback.
Notification callback is expected to be atomic, since it
is called from interrupt context.
- Events are dequeued and processed in a worker thread.

====================
pull-request: bpf-next 2018-10-08
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) sk_lookup_[tcp|udp] and sk_release helpers from Joe Stringer which allow
BPF programs to perform lookups for sockets in a network namespace. This would
allow programs to determine early on in processing whether the stack is
expecting to receive the packet, and perform some action (eg drop,
forward somewhere) based on this information.
2) per-cpu cgroup local storage from Roman Gushchin.
Per-cpu cgroup local storage is very similar to simple cgroup storage
except all the data is per-cpu. The main goal of per-cpu variant is to
implement super fast counters (e.g. packet counters), which don't require
neither lookups, neither atomic operations in a fast path.
The example of these hybrid counters is in selftests/bpf/netcnt_prog.c
3) allow HW offload of programs with BPF-to-BPF function calls from Quentin Monnet
4) support more than 64-byte key/value in HW offloaded BPF maps from Jakub Kicinski
5) rename of libbpf interfaces from Andrey Ignatov.
libbpf is maturing as a library and should follow good practices in
library design and implementation to play well with other libraries.
This patch set brings consistent naming convention to global symbols.
6) relicense libbpf as LGPL-2.1 OR BSD-2-Clause from Alexei Starovoitov
to let Apache2 projects use libbpf
7) various AF_XDP fixes from Björn and Magnus

Until now, both Rx and Tx confirmation frames handled during
NAPI poll were counted toward the NAPI budget. However, Tx
confirmations are lighter to process than Rx frames, which can
skew the amount of work actually done inside one NAPI cycle.
Update the code to only count Rx frames toward the NAPI budget
and set a separate threshold on how many Tx conf frames can be
processed in one poll cycle.
The NAPI poll routine stops when either the budget is consumed
by Rx frames or when Tx confirmation frames reach this threshold.

Mark instructions that use pointers to areas in the stack outside of the
current stack frame, and process them accordingly in mem_op_stack().
This way, we also support BPF-to-BPF calls where the caller passes a
pointer to data in its own stack frame to the callee (typically, when
the caller passes an address to one of its local variables located in
the stack, as an argument).

When pre-processing the instructions, it is trivial to detect what
subprograms are using R6, R7, R8 or R9 as destination registers. If a
subprogram uses none of those, then we do not need to jump to the
subroutines dedicated to saving and restoring callee-saved registers in
its prologue and epilogue.
This patch introduces detection of callee-saved registers in subprograms
and prevents the JIT from adding calls to those subroutines whenever we
can: we save some instructions in the translated program, and some time
at runtime on BPF-to-BPF calls and returns.
If no subprogram needs to save those registers, we can avoid appending
the subroutines at the end of the program.

On performing a BPF-to-BPF call, we first jump to a subroutine that
pushes callee-saved registers (R6~R9) to the stack, and from there we
goes to the start of the callee next. In order to do so, the caller must
pass to the subroutine the address of the NFP instruction to jump to at
the end of that subroutine. This cannot be reliably implemented when
translated the caller, as we do not always know the start offset of the
callee yet.
This patch implement the required fixup step for passing the start
offset in the callee via the register used by the subroutine to hold its
return address.

Offloaded programs using BPF-to-BPF calls use the stack to store the
return address when calling into a subprogram. Callees also need some
space to save eBPF registers R6 to R9. And contrarily to kernel
verifier, we align stack frames on 64 bytes (and not 32). Account for
all this when checking the stack size limit before JIT-ing the program.
This means we have to recompute maximum stack usage for the program, we
cannot get the value from the kernel.
In addition to adapting the checks on stack usage, move them to the
finalize() callback, now that we have it and because such checks are
part of the verification step rather than translation.

This is the main patch for the logics of BPF-to-BPF calls in the nfp
driver.
The functions called on BPF_JUMP | BPF_CALL and BPF_JUMP | BPF_EXIT were
used to call helpers and exit from the program, respectively; make them
usable for calling into, or returning from, a BPF subprogram as well.
For all calls, push the return address as well as the callee-saved
registers (R6 to R9) to the stack, and pop them upon returning from the
calls. In order to limit the overhead in terms of instruction number,
this is done through dedicated subroutines. Jumping to the callee
actually consists in jumping to the subroutine, that "returns" to the
callee: this will require some fixup for passing the address in a later
patch. Similarly, returning consists in jumping to the subroutine, which
pops registers and then return directly to the caller (but no fixup is
needed here).
Return to the caller is performed with the RTN instruction newly added
to the JIT.
For the few steps where we need to know what subprogram an instruction
belongs to, the struct nfp_insn_meta is extended with a new subprog_idx
field.
Note that checks on the available stack size, to take into account the
additional requirements associated to BPF-to-BPF calls (storing R6-R9
and return addresses), are added in a later patch.
