When booted with ACPI, random mac addresses are being
assigned to node1 interfaces due to mismatch of bgx_id
in BGX driver and ACPI tables.
This patch fixes this issue by setting maximum BGX devices
per node based on platform/soc instead of a macro. This
change will set the bgx_id appropriately.

ACPI support has been added to ARM IOMMU driver in 4.10 kernel
and that has resulted in VNIC interfaces throwing translation
faults when kernel is booted with ACPI as driver was not using
DMA API. This patch fixes the issue by using DMA API which inturn
will create translation tables when IOMMU is enabled.
Also VNIC doesn't have a seperate receive buffer ring per receive
queue, so there is no 1:1 descriptor index matching between CQE_RX
and the index in buffer ring from where a buffer has been used for
DMA'ing. Unlike other NICs, here it's not possible to maintain dma
address to virt address mappings within the driver. This leaves us
no other choice but to use IOMMU's IOVA address conversion API to
get buffer's virtual address which can be given to network stack
for processing.

Dinesh reported that RTA_MULTIPATH nexthops are 8-bytes larger with IPv6
than IPv4. The recent refactoring for multipath support in netlink
messages does discriminate between non-multipath which needs the OIF
and multipath which adds a rtnexthop struct for each hop making the
RTA_OIF attribute redundant. Resolve by adding a flag to the info
function to skip the oif for multipath.

This restores the ability to set a team device's mtu to anything higher
than 1500. Similar to the reported issue with bonding, the team driver
calls ether_setup(), which sets an initial max_mtu of 1500, while the
underlying hardware can handle something much larger. Just set it to
ETH_MAX_MTU to support all possible values, and the limitations of the
underlying devices will prevent setting anything too large.

Commit a93d01f577 ("RDS: TCP: avoid bad page reference in
rds_tcp_listen_data_ready") added the function
rds_tcp_listen_sock_def_readable() to handle the case when a
partially set-up acceptor socket drops into rds_tcp_listen_data_ready().
However, if the listen socket (rtn->rds_tcp_listen_sock) is itself going
through a tear-down via rds_tcp_listen_stop(), the (*ready)() will be
null and we would hit a panic of the form
BUG: unable to handle kernel NULL pointer dereference at (null)

:
In the above case, it is not fatal to encounter a NULL value for
ready- we should just drop the packet and let the flush of the
acceptor thread finish gracefully.
In general, the tear-down sequence for listen() and accept() socket
that is ensured by this commit is:
rtn->rds_tcp_listen_sock = NULL; /* prevent any new accepts */

Order of initialization in rds_tcp_init needs to be done so
that resources are set up and destroyed in the correct synchronization
sequence with both the data path, as well as netns create/destroy
path. Specifically,
- we must call register_pernet_subsys and get the rds_tcp_netid
before calling register_netdevice_notifier, otherwise we risk
the sequence
1. register_netdevice_notifier sets up netdev notifier callback
2. rds_tcp_dev_event -> rds_tcp_kill_sock uses netid 0, and finds
the wrong rtn, resulting in a panic with string that is of the form:

en_tc.c:(.text.mlx5e_create_encap_header_ipv6+0x110): undefined reference to `ip6_route_output_flags'
This adds a dependency to ensure that MLX5_CORE_EN can only be built
if we are able link the kernel successfully. The downside is that the
ethernet option can be hidden. Alternatively we could make MLX5_CORE
depend on "IPV6 || !IPV6", which would force MLX5_CORE to be a module
