net: enetc: distinguish error from valid pointers in enetc_fixup_clear_rss_rfs()

enetc_psi_create() returns an ERR_PTR() or a valid station interface
pointer, but checking for the non-NULL quality of the return code blurs
that difference away. So if enetc_psi_create() fails, we call
enetc_psi_destroy() when we shouldn't. This will likely result in
crashes, since enetc_psi_create() cleans up everything after itself when
it returns an ERR_PTR().

Rob's suggestion is to reimplement the enetc driver workaround as a
PCI fixup, and to modify the PCI core to run the fixups for all PCI
functions. This change handles the first part.

We refactor the common code in enetc_psi_create() and enetc_psi_destroy(),
and use the PCI fixup only for those functions for which enetc_pf_probe()
won't get called. This avoids some work being done twice for the PFs
which are enabled.

drivers: net: turn on XDP features

A summary of the flags being set for various drivers is given below.
Note that XDP_F_REDIRECT_TARGET and XDP_F_FRAG_TARGET are features
that can be turned off and on at runtime. This means that these flags
may be set and unset under RTNL lock protection by the driver. Hence,
READ_ONCE must be used by code loading the flag value.

Also, these flags are not used for synchronization against the availability
of XDP resources on a device. It is merely a hint, and hence the read
may race with the actual teardown of XDP resources on the device. This
may change in the future, e.g. operations taking a reference on the XDP
resources of the driver, and in turn inhibiting turning off this flag.
However, for now, it can only be used as a hint to check whether device
supports becoming a redirection target.

- netronome (nfp)

net: enetc: stop auto-configuring the port pMAC

The pMAC (ENETC_PFPMR_PMACE) is probably unconditionally enabled in the
enetc driver to allow RX of preemptible packets and not see them as
error frames. I don't know why TX preemption (ENETC_MMCSR_ME) is enabled
though. With no way to say which traffic classes are preemptible (all
are express by default), no preemptible frames would be transmitted
anyway.

Lastly, it may have been believed that the register write lock-step mode
(now deleted) needed the pMAC to be enabled at all times. I don't know
if that's true. However, I've checked that driver writes to PM1
registers do propagate through to the ENETC IP even when the pMAC is
disabled.

With such incomplete support for frame preemption, it's best to just
remove whatever exists right now and come with something more coherent
later.

Currently the enetc driver duplicates its writes to the PM0 registers

Create enetc_port_mac_wr() which writes both the PM0 and PM1 register
with the same value (if frame preemption is supported on this port).
Also create enetc_port_mac_rd() which reads from PM0 - the assumption
being that PM1 contains just the same value.

This will be necessary when we enable the MAC Merge layer properly, and
the pMAC becomes operational.

net: enetc: stop configuring pMAC in lockstep with eMAC

The MWLM bit (MAC write lock-step mode) allows register writes to the
pMAC to be auto-performed whenever the corresponding eMAC register is
written by the driver. This allows their configuration to remain
in sync.

The driver has set this bit since the initial commit, but it doesn't do
anything, since the hardware feature doesn't work (and the bit has been
removed from more recent versions of the documentation).

The driver does attempt, more or less, to keep those MAC registers in
sync by writing the same value once to e.g. ENETC_PM0_CMD_CFG (eMAC) and
once to ENETC_PM1_CMD_CFG (pMAC). Because the lockstep feature doesn't
work, that's what it will stick to.

Right now, a PHY-less port (no phy-mode, no fixed-link, no phy-handle)
doesn't register with phylink, but calls netif_carrier_on() from
enetc_start().

This makes sense for a VF, but for a PF, this is braindead, because we
never call enetc_mac_enable() so the MAC is left inoperational.
Furthermore, commit 71b77a7a27a3 ("enetc: Migrate to PHYLINK and
PCS_LYNX") put the nail in the coffin because it removed the initial
netif_carrier_off() call done right after register_netdev().

Without that call, netif_carrier_on() does not call
linkwatch_fire_event(), so the operstate remains IF_OPER_UNKNOWN.

Just deny the broken configuration by requiring that a phy-mode is
present, and always register a PF with phylink.

net: enetc: manage ENETC_F_QBV in priv->active_offloads only when enabled

Future work in this driver would like to look at priv->active_offloads &
ENETC_F_QBV to determine whether a tc-taprio qdisc offload was
installed, but this does not produce the intended effect.

All the other flags in priv->active_offloads are managed dynamically,
except ENETC_F_QBV which is set statically based on the probed SI capability.

This change makes priv->active_offloads & ENETC_F_QBV really track the
presence of a tc-taprio schedule on the port.

Some existing users, like the enetc_sched_speed_set() call from
phylink_mac_link_up(), are best kept using the old logic: the tc-taprio
offload does not re-trigger another link mode resolve, so the scheduler
needs to be functional from the get go, as long as Qbv is supported at
all on the port. So to preserve functionality there, look at the static
station interface capability from pf->si->hw_features instead.

ethernet: enetc: use eth_hw_addr_set()

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.

Pass a netdev into the helper instead of just the address,
read the address into an array on the stack, then call
eth_hw_addr_set().

net: enetc: add support for software TSO

This patch adds support for driver level TSO in the enetc driver using
the TSO API.

Beside using the usual tso_build_hdr(), tso_build_data() this specific
implementation also has to compute the checksum, both IP and L4, for
each resulted segment. This is because the ENETC controller does not
support Tx checksum offload which is needed in order to take advantage
of TSO.

With the workaround for the ENETC MDIO erratum in place the Tx path of
the driver is forced to lock/unlock for each skb sent. This is why, even
though we are computing the checksum by hand we see the following
improvement in TCP termination on the LS1028A SoC, on a single A72 core
running at 1.3GHz:

before: 1.63 Gbits/sec
after: 2.34 Gbits/sec
