ice_is_tc_ena is used to check whether a given traffic class is
enabled. Because there are only 8 traffic classes, the function took
a u8 bitmap. This causes problems because it is cast to an unsigned
long causing a static analysis warning regarding Out-of-bounds read.
Fix this by simply updating ice_is_tc_ena to take an unsigned long.
Passing a u8 to this function should implicitly convert the value.

Check num_queue_pairs to avoid access to unallocated field of
vsi->tx_rings/vsi->rx_rings. Without this validation we can set
vsi->alloc_txq/vsi->alloc_rxq to value smaller than ICE_MAX_BASE_QS_PER_VF
and send this command with num_queue_pairs greater than
vsi->alloc_txq/vsi->alloc_rxq. This lead to access to unallocated memory.
In VF vsi alloc_txq and alloc_rxq should be the same. Get minimum
because looks more readable.
Also add validation for ring_len param. It should be greater than 32 and
be multiple of 32. Incorrect value leads to hang traffic on PF.

In case of MDD events on VF, don't clog kernel log with unlimited VF MDD
events message "VF 0 has had 1018 MDD events since last boot" - limit
events log message to 30, based on the observation in some experimentation
with sending malicious packet once, and number of events reported before
device stopped observing MDD events.
Also removed defunct macro "ICE_DFLT_NUM_MDD_EVENTS_ALLOWED" for tracking
number of MDD events allowed before disabling the interface...

This patch fixes the issue where port and PFC statistics counters are
incrementing at the wrong port with 4x25G cards.
Read the GLPRT port registers using lport parameter instead of pf_id to
update the statistics otherwise the pf_ids are flipped for ports 2 and 3
when read from the HW register PF_FUNC_RID and this is expected as per

Without rtnl lock protection filters can no longer safely manage block
offloads counter themselves. Refactor cls API to protect block offloadcnt
with tcf_block->cb_lock that is already used to protect driver callback
list and nooffloaddevcnt counter. The counter can be modified by concurrent
tasks by new functions that execute block callbacks (which is safe with
previous patch that changed its type to atomic_t), however, block
bind/unbind code that checks the counter value takes cb_lock in write mode
to exclude any concurrent modifications. This approach prevents race
conditions between bind/unbind and callback execution code but allows for
concurrency for tc rule update path.
Move block offload counter, filter in hardware counter and filter flags
management from classifiers into cls hardware offloads API. Make functions
tcf_block_offload_{inc|dec}() and tc_cls_offload_cnt_update() to be cls API
private. Implement following new cls API to be used instead:
tc_setup_cb_add() - non-destructive filter add. If filter that wasn't
already in hardware is successfully offloaded, increment block offloads
counter, set filter in hardware counter and flag. On failure, previously
offloaded filter is considered to be intact and offloads counter is not
decremented.
tc_setup_cb_replace() - destructive filter replace. Release existing
filter block offload counter and reset its in hardware counter and flag.
Set new filter in hardware counter and flag. On failure, previously
offloaded filter is considered to be destroyed and offload counter is
decremented.
tc_setup_cb_destroy() - filter destroy. Unconditionally decrement block
offloads counter.
tc_setup_cb_reoffload() - reoffload filter to single cb. Execute cb() and
call tc_cls_offload_cnt_update() if cb() didn't return an error.
Refactor all offload-capable classifiers to atomically offload filters to
hardware, change block offload counter, and set filter in hardware counter
and flag by means of the new cls API functions.

In order to remove dependency on rtnl lock, extend tcf_block with 'cb_lock'
rwsem and use it to protect flow_block->cb_list and related counters from
concurrent modification. The lock is taken in read mode for read-only
traversal of cb_list in tc_setup_cb_call() and write mode in all other
cases. This approach ensures that:
- cb_list is not changed concurrently while filters is being offloaded on
block.
- block->nooffloaddevcnt is checked while holding the lock in read mode,
but is only changed by bind/unbind code when holding the cb_lock in write
mode to prevent concurrent modification.

IQD devices offer limited support for bulking: all frames in a TX buffer
need to have the same target. qeth_iqd_may_bulk() implements this
constraint, and allows us to defer the TX doorbell until
(a) the buffer is full (since each buffer needs its own doorbell), or
(b) the entire TX queue is full, or
(b) we reached the BQL limit.

Due to their large MTU and potentially low utilization of TX buffers,
IQD devices in particular require fast TX recycling. This makes them
a prime candidate for a TX NAPI path in qeth.
qeth_tx_poll() uses the recently introduced qdio_inspect_queue() helper
to poll the TX queue for completed buffers. To avoid hogging the CPU for
too long, we yield to the stack after completing an entire queue's worth
of buffers.
While IQD is expected to transfer its buffers synchronously (and thus
doesn't support TX interrupts), a timer covers for the odd case where a
TX buffer doesn't complete synchronously. Currently this timer should
only ever fire for
(1) the mcast queue,
(2) the occasional race, where the NAPI poll code observes an update to
queue->used_buffers while the TX doorbell hasn't been issued yet.

This consolidates the SW statistics code, and improves it to
(1) account for the header overhead of each segment on a TSO skb,
(2) count dangling packets as in-error (during eg. shutdown), and
(3) only count offloads when the skb was successfully transmitted.
We also count each segment of an TSO skb as one packet - except for
tx_dropped, to be consistent with dev->tx_dropped.

If a driver wants to use the new Output Queue poll code, then the qdio
layer must disable its internal Queue scanning. Let the driver select
this mode by passing a special scan_threshold of 0.
As the scan_threshold is the same for all Output Queues, also move it
into the main qdio_irq struct. This allows for fast opt-out checking, a
driver is expected to operate either _all_ or none of its Output Queues
in polling mode.

While commit d36deae75011 ("qdio: extend API to allow polling") enhanced
the qdio layer so that drivers can poll their Input Queues, we don't
have the corresponding infrastructure for Output Queues yet.
Factor out a helper that scans a single QDIO Queue, so that qeth can
implement TX NAPI on top of it.
While doing so, remove the duplicated tracking of the next-to-scan index
(q->first_to_check vs q->first_to_kick) in this code path.
qdio_handle_aobs() needs to move slightly upwards in the code hierarchy,
so that it's still called from the polling path.

Recent commit added logic to determine the appropriate statistics block
size to allocate and the size is stored in bp->hw_ring_stats_size. But
if the firmware spec is older than 1.6.0, it is 0 and not initialized.
This causes the allocation to fail with size 0 and bnxt_open() to
abort. Fix it by always initializing bp->hw_ring_stats_size to the
legacy default size value.

Add a helper function "rtl_eee_enable" for setting EEE. Besides, I
move r8153_eee_en() and r8153b_eee_en(). And, I remove r8152b_enable_eee(),
r8153_set_eee(), and r8153b_set_eee().

If a VSI is not using a unicast filter or did not configure that
particular unicast filter, driver should not allow it to be removed
by the rogue VSI.

VSI, especially VF could request to add or remove filter for another VSI,
driver should really guide such request and disallow it.
However, instead of returning error for such malicious request, driver
can simply return success.
In addition, we are not tracking number of MAC filters configured per
VF correctly - and this leads to issue updating VF MAC filters whenever
they were removed and re-configured via bringing VF interface down and
up. Also, since VF could send request to update multiple MAC filters at
once, driver should program those filters individually in the switch, in
order to determine which action resulted to error, and communicate
accordingly to the VF.
So, with this changes, we now track number of filters added right from
when VF resources allocation is done, and could properly add filters for
both trusted and non_trusted VFs, without MAC filters mis-match issue in
the switch...
Also refactor code, so that driver can use new function to add or remove
MAC filters.

Users expect ethtool statistics to be updated on-demand when invoking
'ethtool -S <iface>' instead of providing a snapshot of statistics taken
once a second (the frequency of the watchdog task where stats are currently
updated). Update stats every time 'ethtool -S <iface>' is run.
Also, fix an indentation style issue and an unnecessary local variable
initialization in ice_get_ethtool_stats() discovered while investigating
the subject issue.

Move the assignment to local variables after validation.
Remove unnecessary checks in ice_vc_process_vf_msg() as the respective
functions are now performing the checks.

In some circumstances, VF devices can be deactivated while a message is
in-flight. In that case, a series of scary error message will be
printed in the log. Since these are actually harmless, check for this
case and suppress them. No harm, no foul.

The current flag name of "enable-fw-lldp" is a bit cumbersome.
Change priv-flag name to "fw-lldp-agent" with a value of on or
off. This is more straight-forward in meaning.
