When a Tx timestamp is requested, a pointer to the skb is stored in the
ravb_tstamp_skb struct. This was done without an skb_get. There exists
the possibility that the skb could be freed by ravb_tx_free (when
ravb_tx_free is called from ravb_start_xmit) before the timestamp was
processed, leading to a use-after-free bug.
Use skb_get when filling a ravb_tstamp_skb struct, and add appropriate
frees/consumes when a ravb_tstamp_skb struct is freed.

tc transparently maps the software priority number to hardware. Update
it to pass the major priority which is what most drivers expect. Update
drivers too so they do not need to lshift the priority field of the
flow_cls_common_offload object. The stmmac driver is an exception, since
this code assumes the tc software priority is fine, therefore, lshift it
just to be conservative.

Instead unmap it when the hypervisor call has completed. This patch
avoids the possibility that a buffer will not be unmapped because
a TX completion is lost or mishandled.

FW expects the driver to provide unique flow reference handles
for Tx or Rx flows. When a Tx flow and an Rx flow end up sharing
a reference handle, flow offload does not seem to work.
This could happen in the case of 2 flows having their L2 fields
wildcarded but in different direction.
Fix to incorporate the flow direction as part of the L2 key
v2: Move the dir field to the end of the bnxt_tc_l2_key struct to
fix the warning reported by kbuild test robot <lkp@intel.com>.
There is existing code that initializes the structure using
nested initializer and will warn with the new u8 field added to
the beginning. The structure also packs nicer when this new u8 is
added to the end of the structure [MChan].

Direction of the flow is determined using src_fid. For an RX flow,
src_fid is PF's fid and for TX flow, src_fid is VF's fid. Direction
of the flow must be specified, when getting statistics for that flow.
Currently, for DECAP flow, direction is determined incorrectly, i.e.,
direction is initialized as TX for DECAP flow, instead of RX. Because
of which, stats are not reported for this DECAP flow, though it is
offloaded and there is traffic for that flow, resulting in flow age out.
This patch fixes the problem by determining the DECAP flow's direction
using correct fid. Set the flow direction in all cases for consistency
even if 64-bit flow handle is not used.

When both RX buffers and RX aggregation buffers have to be
replenished at the end of NAPI, post the RX aggregation buffers first
before RX buffers. Otherwise, we may run into a situation where
there are only RX buffers without RX aggregation buffers for a split
second. This will cause the hardware to abort the RX packet and
report buffer errors, which will cause unnecessary cleanup by the
driver.
Ringing the Aggregation ring doorbell first before the RX ring doorbell
will prevent some of these buffer errors. Use the same sequence during
ring initialization as well.

During device shutdown, the VNIC clearing sequence needs to be modified
to free the VNIC first before freeing the RSS contexts. The current

of RSS contexts is not required with the new sequence.
Refactor the VNIC clearing logic into a new function bnxt_clear_vnic()

In struct frame_info, the cpuq member is never used. This cosmetic patch
removes it from the structure, and from the parsing of the frame header
as it's only set but never used.

The patch adds driver interface for reading the config attributes from user
provided buffer, and updates these values on nvm config flash partition.
This is basically an expansion of our existing ethtool -f implementation.
The management FW has exposed an additional method of configuring some of
the nvram options, and this makes use of that. This implementation will
come into use when newer FW files which contain configuration directives
employing this API will be provided to ethtool -f.

In myri10ge_probe(), myri10ge_alloc_slices() is invoked to allocate slices
related structures. Later on, myri10ge_request_irq() is used to get an irq.
However, if this process fails, the allocated slices related structures are
not deallocated, leading to memory leaks. To fix this issue, revise the
target label of the goto statement to 'abort_with_slices'.

If oct->fn_list.enable_io_queues() fails, no cleanup is executed, leading
to memory/resource leaks. To fix this issue, invoke
octeon_delete_instr_queue() before returning from the function.
