AHG may be armed to use the stored header, which by design is limited
to edits in the PSN/A 32 bit word (bth2).
When the code is trying to send a BECN, the use of the stored header
will lose the BECN bit.
Fix by avoiding AHG when getting ready to send a BECN. This is
accomplished by always claiming the packet is not a middle packet which
is an AHG precursor. BECNs are not a normal case and this should not
hurt AHG optimizations.

The code for handling a marked UD packet unconditionally returns the
dlid in the header of the FECN marked packet. This is not correct
for multicast packets where the DLID is in the multicast range.
The subsequent attempt to send the CNP with the multicast lid will
cause the chip to halt the ack send context because the source
lid doesn't match the chip programming. The send context will
be halted and flush any other pending packets in the pio ring causing
the CNP to not be sent.
A part of investigating the fix, it was determined that the 16B work
broke the FECN routine badly with inconsistent use of 16 bit and 32 bits
types for lids and pkeys. Since the port's source lid was correctly 32
bits the type mixmatches need to be dealt with at the same time as
fixing the CNP header issue.
Fix these issues by:
- Using the ports lid for as the SLID for responding to FECN marked UD
packets
- Insure pkey is always 16 bit in this and subordinate routines
- Insure lids are 32 bits in this and subordinate routines

Currently, the kernel protects access to the agent ID allocator on a per
port basis using a spinlock, so it is impossible for two apps/threads on
the same port to get the same TID, but it is entirely possible for two
threads on different ports to end up with the same TID.
As this can be confusing (regardless of it being legal according to the
IB Spec 1.3, C13-18.1.1, in section 13.4.6.4 - TransactionID usage),
and as the rdma-core user space API for /dev/umad devices implies unique
TIDs even across ports, make the TID an atomic type so that no two
allocations, regardless of port number, will be the same.

There are few issues with validation of netdevice and listen id lookup
for IB (IPoIB) while processing incoming CM request as below.
1. While performing lookup of bind_list in cma_ps_find(), net namespace
of the netdevice can get deleted in cma_exit_net(), resulting in use
after free access of idr and/or net namespace structures.
This lookup occurs from the workqueue context (and not userspace
context where net namespace is always valid).
CPU0 CPU1
==== ====
bind_list = cma_ps_find();
move netdevice to new namespace
delete net namespace
cma_exit_net()
idr_destroy(idr);
[..]
cma_find_listener(bind_list, ..);
2. While netdevice is validated for IP address in given net namespace,
netdevice's net namespace and/or ifindex can change in
cma_get_net_dev() and cma_match_net_dev().
Above issues are overcome by using rcu lock along with netdevice
UP/DOWN state as described below.
When a net namespace is getting deleted, netdevice is closed and
shutdown before moving it back to init_net namespace.
change_net_namespace() synchronizes with any existing use of netdevice
before changing the netdev properties such as net or ifindex.
Once netdevice IFF_UP flags is cleared, such fields are not guaranteed
to be valid.
Therefore, rcu lock along with netdevice state check ensures that,
while route lookup and cm_id lookup is in progress, netdevice of
interest won't migrate to any other net namespace.
This ensures that associated net namespace of netdevice won't get
deleted while rcu lock is held for netdevice which is in IFF_UP state.

del_netdev_default_ips()

However, ib_cache_gid_del() was not getting invoked in non bonding
scenarios because event_ndev and rdma_ndev are same.
Therefore, fix such condition to ignore checking upper device when event
ndev and rdma_dev are same; similar to bond_set_netdev_default_gids().
Which this fix ib_cache_gid_del() is invoked correctly; however
ib_cache_gid_del() doesn't find the default GID for deletion because
find_gid() was given default_gid = false with
GID_ATTR_FIND_MASK_DEFAULT set.
But it was getting overwritten by ib_cache_gid_set_default_gid() later
on as part of add_cmd().
Therefore, mac address change used to work for default GID.
With refactor series [1], this incorrect behavior is detected.
Therefore,
when deleting default GID, set default_gid and set MASK flag.
when deleting IP based GID, clear default_gid and set MASK flag.

Fix build errors when INFINIBAND_USER_ACCESS=m and MLX5_INFINIBAND=y.
The build error occurs when the mlx5 driver code attempts to use
USER_ACCESS interfaces, which are built as a loadable module.
Fixes these build errors:
drivers/infiniband/hw/mlx5/main.o: In function `populate_specs_root':
../drivers/infiniband/hw/mlx5/main.c:4982: undefined reference to `uverbs_default_get_objects'
../drivers/infiniband/hw/mlx5/main.c:4994: undefined reference to `uverbs_alloc_spec_tree'
drivers/infiniband/hw/mlx5/main.o: In function `depopulate_specs_root':
../drivers/infiniband/hw/mlx5/main.c:5001: undefined reference to `uverbs_free_spec_tree'
Build-tested with multiple config combinations.
