This patch fixes the problem where the ethtool Supported link
modes list backplane interfaces on X722 devices for 10GbE with
SFP+ and Cortina retimer. This patch fixes the problem by setting
and using a flag for this particular device since the backplane
interface is only between the internal PHY and the retimer and it
should not be seen by the user as they cannot use it.
Without this patch, the user wrongly thinks that backplane interfaces
are supported on their device when they actually are not.

The PHY type value for unrecognized PHYs and cables was changed
based on firmware version number. Newer hardware use lower firmware
version numbers and this was causing some PHYs to be identified
as type 0x16 instead of 0xe (unknown).
Without this patch, newer card will incorrectly identify unknown
PHYs and cables.
This change adds hardware type to the check for firmware version
so the PHY type is reported correctly.

Armada 3700 is a new ARMv8 SoC from Marvell using same network controller
as older Armada 370/38x/XP. There are however some differences that
needed taking into account when adding support for it:
* open default MBUS window to 4GB of DRAM - Armada 3700 SoC's Mbus
configuration for network controller has to be done on two levels:
global and per-port. The first one is inherited from the
bootloader. The latter can be opened in a default way, leaving
arbitration to the bus controller. Hence filled mbus_dram_target_info
structure is not needed
* make per-CPU operation optional - Recent patches adding RSS and XPS
support for Armada 38x/XP enabled per-CPU operation of the controller
by default. Contrary to older SoC's Armada 3700 SoC's network
controller is not capable of per-CPU processing due to interrupt lines'
connectivity. This patch restores non-per-CPU operation, which is now
optional and depends on neta_armada3700 flag value in mvneta_port
structure. In order not to complicate the code, separate interrupt
subroutine is implemented.
For now, on the Armada 3700, RSS is disabled as the current
implementation depend on the per cpu interrupts.

Until now the virtual address of the received buffer were stored in the
cookie field of the rx descriptor. However, this field is 32-bits only
which prevents to use the driver on a 64-bits architecture.
With this patch the virtual address is stored in an array not shared with
the hardware (no more need to use the DMA API). Thanks to this, it is
possible to use cache contrary to the access of the rx descriptor member.
The change is done in the swbm path only because the hwbm uses the cookie
field, this also means that currently the hwbm is not usable in 64-bits.

Transmit queue timeout issue is seen in two cases
- Due to a race condition btw setting stop_queue at xmit()
and checking for stopped_queue in NAPI poll routine, at times
transmission from a SQ comes to a halt. This is fixed
by using barriers and also added a check for SQ free descriptors,
incase SQ is stopped and there are only CQE_RX i.e no CQE_TX.
- Contrary to an assumption, a HW errata where HW doesn't stop transmission
even though there are not enough CQEs available for a CQE_TX is
not fixed in T88 pass 2.x. This results in a Qset error with
'CQ_WR_FULL' stalling transmission. This is fixed by adjusting
RXQ's RED levels for CQ level such that there is always enough
space left for CQE_TXs.

After 326fe02d1e ("net/mlx4_en: protect ring->xdp_prog with rcu_read_lock"),
the rcu_read_lock() in bpf_prog_run_xdp() is superfluous, since callers
need to hold rcu_read_lock() already to make sure BPF program doesn't
get released in the background.
Thus, drop it from bpf_prog_run_xdp(), as it can otherwise be misleading.
Still keeping the bpf_prog_run_xdp() is useful as it allows for grepping
in XDP supported drivers and to keep the typecheck on the context intact.
For mlx4, this means we don't have a double rcu_read_lock() anymore. nfp can
just make use of bpf_prog_run_xdp(), too. For qede, just move rcu_read_lock()
out of the helper. When the driver gets atomic replace support, this will
move to call-sites eventually.
mlx5 needs actual fixing as it has the same issue as described already in
326fe02d1e ("net/mlx4_en: protect ring->xdp_prog with rcu_read_lock"),
that is, we're under RCU bh at this time, BPF programs are released via
call_rcu(), and call_rcu() != call_rcu_bh(), so we need to properly mark
read side as programs can get xchg()'ed in mlx5e_xdp_set() without queue
reset.

Add support for the (optional) SGMII PCS functionality of the Altera
TSE MAC. If the phy-mode is set to 'sgmii' then we attempt to discover
and initialise the PCS so that the MAC can communicate to the PHY.
The PCS IP block provides a scratch register for testing presence of
the PCS, which is mapped into one of the two MDIO spaces present in
the MAC's register space. Once we have determined that the scratch
register is functioning, we attempt to initialise the PCS to
auto-negotiate an SGMII link with the PHY. There is no need to monitor
or manage the SGMII link beyond this, since the normal PHY MDIO will
then be used to monitor the media layer.
The Altera TSE MAC has only one way in which it can be configured with an
SGMII PCS, and as such, this patch only looks to the phy-mode to select
whether or not to attempt to initialise the PCS registers. During
initialisation, we report the PCS's equivalent of a PHY ID register.
This can be parameterised during the IP instantiation and is often left
as '0x00000000' which is not an error.

To connect two ports of the same configuration (MDI to MDI or
MDI-X to MDI-X) with a 10/100/1000 Mbit/s connection, an
Ethernet crossover cable is needed to cross over the transmit
and receive signals in the cable, so that they are matched at
the connector level.
When connecting an MDI port to an MDI-X port a straight through
cable is used while to connect two MDI ports or two MDI-X ports
a crossover cable must be used. Conventionally MDI is used on end
devices while MDI-X is used on hubs and switches
Auto MDI-X automatically detects the required cable connection
type and configures the connection appropriately, removing the
need for crossover cables to interconnect switches or connecting
PCs peer-to-peer.
