net/rds: SOL_RDS socket option to explicitly select transport

Today the underlying transport (TCP or IB) for a PF_RDS socket is
implicitly selected based on the local address used to bind(2) the
PF_RDS socket. This results in some non-deterministic behavior when
there are un-numbered and IPoIB interfaces sharing the same IP address.
It also places the constraint that the IB interface must have an IP
address (and thus, IPoIB) configured on it.

The non-determinism may be avoided by providing the user-space application
a socket option that allows it to explicitly select the transport
prior to bind(2).

Patch 1 of this series provides the constant definitions needed by
the application via <linux/rds.h>.

Patch 2 provides the setsockopt support, and Patch 3 provides the
getsockopt support.

The currently attached transport for a PF_RDS socket may be obtained
from user space by invoking getsockopt(2) using the SO_RDS_TRANSPORT
option at the SOL_RDS level. The integer optval returned will be one
of the RDS_TRANS_* constants defined in linux/rds.h.

An application may deterministically attach the underlying transport for
a PF_RDS socket by invoking setsockopt(2) with the SO_RDS_TRANSPORT
option at the SOL_RDS level. The integer argument to setsockopt must be
one of the RDS_TRANS_* transport types, e.g., RDS_TRANS_TCP. The option
must be specified before invoking bind(2) on the socket, and may only
be used once on the socket. An attempt to set the option on a bound
socket, or to invoke the option after a successful SO_RDS_TRANSPORT
attachment, will return EOPNOTSUPP.

Normally the program attachment place (like sockets, qdiscs) takes
care of rcu protection and calls bpf_prog_put() after a grace period.
The programs stored inside prog_array may not be attached anywhere,
so prog_array needs to take care of preserving rcu protection.
Otherwise bpf_tail_call() will race with bpf_prog_put().
To solve that introduce bpf_prog_put_rcu() helper function and use
it in 3 places where unattached program can decrement refcnt:
closing program fd, deleting/replacing program in prog_array.

Currently, bcm_sysport_desc_rx() calls bcm_sysport_rx_refill() at the end of Rx
packet processing loop, after the current Rx packet has already been passed to
napi_gro_receive(). However, bcm_sysport_rx_refill() might fail to allocate a new
Rx skb, thus leaving a hole on the Rx queue where no valid Rx buffer exists.

To eliminate this situation:

1. Rewrite bcm_sysport_rx_refill() to retain the current Rx skb on the
Rx queue if a new replacement Rx skb can't be allocated and DMA-mapped.
In this case, the data on the current Rx skb is effectively dropped.

2. Modify bcm_sysport_desc_rx() to call bcm_sysport_rx_refill() at the
top of Rx packet processing loop, so that the new replacement Rx skb is
already in place before the current Rx skb is processed.

This is loosely inspired from d6707bec ("net: bcmgenet: rewrite

The thunderx ethernet driver fails to build on architectures
that do not have an atomic readq() and writeq() function for
64-bit PCI bus access:

include/asm-generic/io.h:195:23: error: implicit declaration of function 'readq' [-Werror=implicit-function-declaration]

It seems impossible to get this driver to work on most 32-bit
hardware, so it's better to add an explicit dependency, in
order to let us keep building 'allmodconfig' kernels on
all architectures.

As the driver is meant for the internal hardware on an arm64 SoC, this
is not a problem for usability. Allowing the build on all 64-bit
architectures rather than just CONFIG_ARM64 on the other hand means that
we get the benefit of build testing on x86.

Now that EQs management is in the sole responsibility of mlx4_core,
the IRQ affinity hints configuration should be in its hands as well.
request_irq is called only once by the first consumer (maybe mlx4_ib),
so mlx4_en passes the affinity mask too late. We also need to request
vectors according to the cores we want to run on.

mlx4_core distribution of IRQs to cores is straight forward,
EQ(i)->IRQ will set affinity hint to core i.
Consumers need to request EQ vectors, according to their cores
considerations (NUMA).

Previously, mlx4_en allocated EQs and used them exclusively.
This affected RoCE performance, as applications which are
events sensitive were limited to use only the legacy EQs.

Change that by introducing an EQ pool. This pool is managed
by mlx4_core. EQs are assigned to ports (when there are limited
number of EQs, multiple ports could be assigned to the same EQs).

An exception to this rule is the ASYNC EQ which handles various events.

Legacy EQs are completely removed as all EQs could be shared.

When a consumer (mlx4_ib/mlx4_en) requests an EQ, it asks for
EQ serving on a specific port. The core driver calculates which
EQ should be assigned to that request.

Because IRQs are shared between IB and Ethernet modules, their
names only include the PCI device BDF address.

net/mlx5: ConnectX-4 100G Ethernet driver

This patchset extends the mlx5_core driver to support Ethernet
functionality. The Ethernet functionality in the mlx5 driver is
integrated into the core driver and not as separated driver. The
IB functionality remains in the mlx5_ib driver as before.

This functionality will enable the Ethernet capability of Mellanox's new
famility of cards - ConnectX-4. Due to the fact that backword
compatability is being kept, existing Connect-IB cards that are using
this driver are fully working with the modified driver, and no issues
with current deployments should be seen.

Like the ConnectX-3 cards, ConnectX-4 is a VPI (Virtual Port Interface -
every port can be configured as Infiniband or Ethernet) card.
Unlike previous generations, the ConnectX-4 has a separate PCI function
per port.

The current code has a limitation that Infiniband and Ethernet port types
are mutually exclusive. When the driver is compiled with Ethernet
support, the Infiniband functionality is disabled and vice versa. To
control that we added the CONFIG_MLX5_CORE_EN config directive
which is 'n' by default, but can be changed by the user.

This limitation is short-lived and would be addressed soon.

As part of this patchset, mlx5_ifc.h was heavily modified [1]. This file
is now generated automatically from the device specification document.
Since this patch is too big for the mail server, it might be missing in
the mailing list, but could be pulled from an external git repository [2].

irq name selection is done at driver initialization and doesn't contain the
interface name as part of the irq name.
irq_balancer will still work thanks to an improvement introduced by Neil Horman
[3] to use sysfs instead of /proc/interrupts.

Patchset was applied on top of commit ed2dfd90 ("tcp/dccp: warn user for
preferred ip_local_port_range")

This patch contains the driver entry points but does not include

It also adds the option MLX5_CORE_EN to Kconfig to enable/disable the

en_[rt]x.c contains the data path related code specific to tx or rx.
en_txrx.c contains data path code which is common for both the rx and
tx, this is mainly napi related code.

Below are the objects that are being used by the hardware and the driver
in the data path:

Channel - one channel per IRQ. Every channel object contains:
  RQ  - describes the rx queue
  TIR - One TIR (Transport Interface Receive) object per flow type. TIR
        contains attributes for a type of rx flow (e.g IPv4, IPv6 etc).
        A flow is defined in the Flow Table.
        Currently TIR describes the RSS hash parameters if exists and LRO
        attributes.
  SQ  - describes the a tx queue. There is one SQ (Send Queue) per
        TC (traffic class).
  TIS - There is one TIS (Transport Interface Send) per TC.  It
        describes the TC and may later be extended to describe more
	transport properties.

Both RQ and SQ inherit from the object WQ (work queue). This common code
to describe the layout of CQE's WQE's in memory is in the files wq.[cj]

For every channel there is one NAPI context that is used for RX and
for TX.

Driver is using netdev_alloc_skb() to allocate skb's.
