Process QP fatal events from the error event queue.
For that, find the QP, using QPN from the event, and then call its
event_handler. To find the QPs, store created RC QPs in an xarray.

According to the IBA specification:
If a UD request packet is detected with an invalid length, the request
shall be an invalid request and it shall be silently dropped by
the responder. The responder then waits for a new request packet.
commit 689c5421bfe0 ("RDMA/rxe: Fix incorrect responder length checking")
defers responder length check for UD QPs in function `copy_data`.
But it introduces a regression issue for UD QPs.
When the packet size is too large to fit in the receive buffer.
`copy_data` will return error code -EINVAL. Then `send_data_in`
will return RESPST_ERR_MALFORMED_WQE. UD QP will transfer into
ERROR state.

iw_conn_req_handler() associates a new struct rdma_id_private (conn_id) with
an existing struct iw_cm_id (cm_id) as follows:
conn_id->cm_id.iw = cm_id;
cm_id->context = conn_id;
cm_id->cm_handler = cma_iw_handler;
rdma_destroy_id() frees both the cm_id and the struct rdma_id_private. Make
sure that cm_work_handler() does not trigger a use-after-free by only
freeing of the struct rdma_id_private after all pending work has finished.

BNXT_RE_COMP_MASK_UCNTX_HW_RETX_ENABLED was introduced to share the HW
retransmit capability between driver and lib. The main difference in
implementation for HW Retransmit support is the usage of MSN table or
PSN table . When HW retrans is enabled, HW expects MSN table to be
allocated by driver/lib, else PSN table (for older adapters).
FW expose a new field which gives MSN capability. Drivers and libs can
depend on the new field instead of HW Retrasns capability. For
adapters which support HW_RETX feature, MSN table capability will be
set. For older adapters, this value will be 0(to maintain backward
compatibility with older FW).
Rename UAPI just to capture the correct name of the HW capability
that driver/library is interested in. No functional impact even if
older rdma-core is used.

FW reports the HW capability to use PSN table or MSN table and
driver/library need to select it based on this capability.
Use the new capability instead of the older capability check for HW
retransmission while handling the MSN/PSN table. FW report
zero (PSN table) for older adapters to maintain backward compatibility.
Also, Updated the FW interface structures to handle the new fields.

With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.
This means that with:
__string(field, mystring)
Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.
There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:
git grep -l __assign_str | while read a ; do
sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
mv /tmp/test-file $a;
done
I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.
Note, the same updates will need to be done for:
__assign_str_len()
__assign_rel_str()
__assign_rel_str_len()
I tested this with both an allmodconfig and an allyesconfig (build only for both).

Undefined behavior is triggered when bnxt_qplib_alloc_init_hwq is called
with hwq_attr->aux_depth != 0 and hwq_attr->aux_stride == 0.
In that case, "roundup_pow_of_two(hwq_attr->aux_stride)" gets called.
roundup_pow_of_two is documented as undefined for 0.
Fix it in the one caller that had this combination.
The undefined behavior was detected by UBSAN:

Commit 3e2f544dd8a33 ("net: get stats64 if device if driver is
configured") moved the callback to dev_get_tstats64() to net core, so,
unless the driver is doing some custom stats collection, it does not
need to set .ndo_get_stats64.
Since this driver is now relying in NETDEV_PCPU_STAT_TSTATS, then, it
doesn't need to set the dev_get_tstats64() generic .ndo_get_stats64
function pointer.

With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core
instead of in this driver.
With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.
Remove the allocation in the hfi1 driver and leverage the network
core allocation instead.

Convert open coded RMW accesses for LNKCTL2 to use
pcie_capability_clear_and_set_word() which makes its easier to
understand what the code tries to do.
In addition, this futureproofs the code. LNKCTL2 is not really owned by
any driver because it is a collection of control bits that PCI core
might need to touch. RMW accessors already have support for proper
locking for a selected set of registers to avoid losing concurrent
updates (LNKCTL2 is not yet among the registers that need protection
but likely will be in the future).

This patch does a similar change for IPv4.
Instead of (struct rtable *)dst casts, we can use :
#define dst_rtable(_ptr) \
container_of_const(_ptr, struct rtable, dst)
Patch is smaller than IPv6 one, because IPv4 has skb_rtable() helper.
