In smartnic env, if the host (PF) driver is not an e-switch manager, we
are not allowed to apply eswitch ports setups such as vlan (VST),
spoof-checks, min/max rate or state.
Make sure we are eswitch manager when coming to issue these callbacks
and err otherwise.
Also fix the definition of ESW_ALLOWED to rely on eswitch_manager
capability and on the vport_group_manger.
Operations on the VF nic vport context, such as setting a mac or reading
the vport counters are allowed to the PF in this scheme.
The modify nic vport guid code was modified to omit checking the
nic_vport_node_guid_modify eswitch capability.
The reason for doing so is that modifying node guid requires vport group
manager capability, and there's no need to check further capabilities.
1. set_vf_vlan - disallowed
2. set_vf_spoofchk - disallowed
3. set_vf_mac - allowed
4. get_vf_config - allowed
5. set_vf_trust - disallowed
6. set_vf_rate - disallowed
7. get_vf_stat - allowed
8. set_vf_link_state - disallowed

In smartnic env, the host (PF) driver might not be an e-switch
manager, hence the switchdev mode representors are running on
the embedded cpu (EC) and not at the host.
As such, we should avoid dealing with vport representors if
not being esw manager.
While here, make sure to disallow eswitch switchdev related
setups through devlink if we are not esw managers.

In smartnic env, the host (PF) driver might not be an e-switch
manager, hence the FW will err on driver attempts to deal with
setting/unsetting the eswitch and as a result the overall setup
of sriov will fail.
Fix that by avoiding the operation if e-switch management is not
allowed for this driver instance. While here, move to use the
correct name for the esw manager capability name.

eswitch manager
The check for cpu hit statistics was not returning immediate false for
any non vport rep netdev and hence we crashed (say on mlx5 probed VFs) if
user-space tool was calling into any possible netdev in the system.

Call the reoffload tcf_proto_op on all tcf_proto nodes in all chains of a
block when a callback tries to register to a block that already has
offloaded rules. If all existing rules cannot be offloaded then the
registration is rejected. This replaces the previous policy of rejecting
such callback registration outright.
On unregistration of a callback, the rules are flushed for that given cb.
The implementation of block sharing in the NFP driver, for example,
duplicates shared rules to all devs bound to a block. This meant that
rules could still exist in hw even after a device is unbound from a block
(assuming the block still remains active).

When traffic passes through a router port, it needs to be assigned a FID
for ASIC to forward correctly. For bridges, this FID used to be the one
corresponding to VLAN 1. In a previous patch, this was changed to
instead use the PVID at the time that the RIF is created. This patch

Stopping offload completely if replace of program failed dates
back to days of transparent offload. Back then we wanted to
silently fall back to the in-driver processing. Today we mark
programs for offload when they are loaded into the kernel, so
the transparent offload is no longer a reality.
Flags check in the driver will only allow replace of a driver
program with another driver program or an offload program with
another offload program.
When driver program is replaced stopping offload is a no-op,
because driver program isn't offloaded. When replacing
offloaded program if the offload fails the entire operation
will fail all the way back to user space and we should continue
using the old program. IOW when replacing a driver program
stopping offload is unnecessary and when replacing offloaded
program - it's a bug, old program should continue to run.
In practice this bug would mean that if offload operation was to
fail (either due to FW communication error, kernel OOM or new
program being offloaded but for a different netdev) driver
would continue reporting that previous XDP program is offloaded
but in fact no program will be loaded in hardware. The failure
is fairly unlikely (found by inspection, when working on the code)
but it's unpleasant.
Backport note: even though the bug was introduced in commit
cafa92ac2553 ("nfp: bpf: add support for XDP_FLAGS_HW_MODE"),
this fix depends on commit 441a33031fe5 ("net: xdp: don't allow
device-bound programs in driver mode"), so this fix is sufficient
only in v4.15 or newer. Kernels v4.13.x and v4.14.x do need to
stop offload if it was transparent/opportunistic, i.e. if
XDP_FLAGS_HW_MODE was not set on running program.

The r8168 vendor driver always uses value 0x27. In r8169 we have few
chips where 0x17 is used. So far this didn't matter because ASPM was

One of the chips affected by this change is RTL8168E-VL, on my system
with this chip value 0x27 works fine.

Refactor pch_gbe_set_multi in order to avoid unnecessary indentation &
make it clearer what the code is doing.
The one behavioral change from this patch is that we'll no longer
configure the MAC address registers for multicast addresses when the
IFF_PROMISC or IFF_ALLMULTI flags are set. In these cases, just as when
we want to monitor more multicast addresses than we have MAC address
registers, we disable multicast filtering so the MAC address registers
are unused.

The pch_gbe driver sets up multicast address filters using a convoluted
mechanism by which pch_gbe_set_multi allocates an array to hold
multicast addresses, copies desired addresses into that array, calls a
pch_gbe_mac_mc_addr_list_update function which copies addresses out of
that array into MAC registers, then frees the array.
This patch simplifies this somewhat by inlining
pch_gbe_mac_mc_addr_list_update into pch_gbe_set_multi, and removing the
requirement for the MAC addresses to stored consecutively in a single
array.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.
Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.
This simplifies the dependencies, and allows to improve compile-testing.

When using s/w buffer management, buffers are allocated and DMA mapped.
When doing so on an arm64 platform, an offset correction is applied on
the DMA address, before storing it in an Rx descriptor. The issue is
this DMA address is then used later in the Rx path without removing the
offset correction. Thus the DMA address is wrong, which can led to
various issues.
This patch fixes this by removing the offset correction from the DMA
address retrieved from the Rx descriptor before using it in the Rx path.
