In the path for re-enabling FW LLDP engine, there is
a call to register for LLDP MIB change events. This
call is redundant, in that the call to ice_pf_dcb_cfg
will already register the driver for these events. Also,
the call as it stands now is too early in the flow before
before DCB is configured.
Remove the redundant call.

Don't use the mdd_detected variable as an exit condition for this loop;
the first VF to NOT have an MDD event will cause the loop to terminate.
Instead just look at all of the VFs, but don't disable them. This
prevents proper release of resources if the VFs are rebooted or the VF
driver reloaded. Instead, just log a message and call out repeat
offenders.
To make it clear what we are doing, use a differently-named variable in
the loop.

Currently we have two MSI-x (IRQ) trackers, one for OS requested MSI-x
entries (sw_irq_tracker) and one for hardware MSI-x vectors
(hw_irq_tracker). Generally the sw_irq_tracker has less entries than the
hw_irq_tracker because the hw_irq_tracker has entries equal to the max
allowed MSI-x per PF and the sw_irq_tracker is mainly the minimum (non
SR-IOV portion of the vectors, kernel granted IRQs). All of the non
SR-IOV portions of the driver (i.e. LAN queues, RDMA queues, OICR, etc.)
take at least one of each type of tracker resource. SR-IOV only grabs
entries from the hw_irq_tracker. There are a few issues with this approach
that can be seen when doing any kind of device reconfiguration (i.e.
ethtool -L, SR-IOV, etc.). One of them being, any time the driver creates
an ice_q_vector and associates it to a LAN queue pair it will grab and
use one entry from the hw_irq_tracker and one from the sw_irq_tracker.
If the indices on these does not match it will cause a Tx timeout, which
will cause a reset and then the indices will match up again and traffic
will resume. The mismatched indices come from the trackers not being the
same size and/or the search_hint in the two trackers not being equal.
Another reason for the refactor is the co-existence of features with
SR-IOV. If SR-IOV is enabled and the interrupts are taken from the end
of the sw_irq_tracker then other features can no longer use this space
because the hardware has now given the remaining interrupts to SR-IOV.
This patch reworks how we track MSI-x vectors by removing the
hw_irq_tracker completely and instead MSI-x resources needed for SR-IOV
are determined all at once instead of per VF. This can be done because
when creating VFs we know how many are wanted and how many MSI-x vectors
each VF needs. This also allows us to start using MSI-x resources from
the end of the PF's allowed MSI-x vectors so we are less likely to use
entries needed for other features (i.e. RDMA, L2 Offload, etc).
This patch also reworks the ice_res_tracker structure by removing the
search_hint and adding a new member - "end". Instead of having a
search_hint we will always search from 0. The new member, "end", will be
used to manipulate the end of the ice_res_tracker (specifically
sw_irq_tracker) during runtime based on MSI-x vectors needed by SR-IOV.
In the normal case, the end of ice_res_tracker will be equal to the
ice_res_tracker's num_entries.
The sriov_base_vector member was added to the PF structure. It is used
to represent the starting MSI-x index of all the needed MSI-x vectors
for all SR-IOV VFs. Depending on how many MSI-x are needed, SR-IOV may
have to take resources from the sw_irq_tracker. This is done by setting
the sw_irq_tracker->end equal to the pf->sriov_base_vector. When all
SR-IOV VFs are removed then the sw_irq_tracker->end is reset back to
sw_irq_tracker->num_entries. The sriov_base_vector, along with the VF's
number of MSI-x (pf->num_vf_msix), vf_id, and the base MSI-x index on
the PF (pf->hw.func_caps.common_cap.msix_vector_first_id), is used to
calculate the first HW absolute MSI-x index for each VF, which is used
to write to the VPINT_ALLOC[_PCI] and GLINT_VECT2FUNC registers to
program the VFs MSI-x PCI configuration bits. Also, the sriov_base_vector
is used along with VF's num_vf_msix, vf_id, and q_vector->v_idx to
determine the MSI-x register index (used for writing to GLINT_DYN_CTL)
within the PF's space.
Interrupt changes removed any references to hw_base_vector, hw_oicr_idx,
and hw_irq_tracker. Only sw_base_vector, sw_oicr_idx, and sw_irq_tracker
variables remain. Change all of these by removing the "sw_" prefix to
help avoid confusion with these variables and their use.

Currently we set the default number of Rx descriptors per
queue to the system's page size divided by the number of bytes per
descriptor. For 4K page size systems this is resulting in 128 Rx
descriptors per queue. This is causing more dropped packets than desired
in the default configuration. Fix this by setting the minimum default
Rx descriptor count per queue to 512.

In PTP Tx implementation, driver kept scheduling a poll thread until the
timestamp is available. In the error scenarios (e.g. app requesting the
timestamp for non-ptp packet), this thread kept waiting for the timestamp
forever. This patch add changes to report such scenario as an error and
terminate the thread. Added a timeout of 2 seconds i.e., max time to wait
for Tx timestamp. Added a stat value ptp_skip_txts for reporting the number
of packets for which Tx timestamping is skipped.

1GbE Intel Wired LAN Driver Updates 2019-05-28
This series contains updates to e1000e, igb and igc.
Feng adds additional information on a warning message when a read of a

Gustavo A. R. Silva fixes up two "fall through" code comments so that
the checkers can actually determine that we did comment that the case
statement is falling through to the next case.
Sasha does some cleanup on the igc driver by removing duplicate
white space and removed a unneeded workaround for igc. Adds support for
flow control to the igc driver.
Konstantin Khlebnikov reverts a previous fix which was causing a false
positive for a hardware hang. Provides a fix so that when link is lost
the packets in the transmit queue are flushed and wakes the transmit
queue when the NIC is ready to send packets.

When CQE compression is enabled (Multi-host systems), compressed CQEs
might arrive to the driver rx, compressed CQEs don't have a valid hash
offload and the driver already reports a hash value of 0 and invalid hash
type on the skb for compressed CQEs, but this is not good enough.
On a congested PCIe, where CQE compression will kick in aggressively,
gro will deliver lots of out of order packets due to the invalid hash
and this might cause a serious performance drop.
The only valid solution, is to disable rxhash offload at all when CQE
compression is favorable (Multi-host systems).

Before Hardware's reset, it will wait for the driver to write
bit HCLGE_NIC_CMQ_ENABLE of register HCLGE_NIC_CSQ_DEPTH_REG
to 1, while the driver finishes its preparatory work will do that.
BTW, since some cases this register will be cleared, so it needs

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.
This patch fixes the following warning:
drivers/net/ethernet/intel/igb/e1000_82575.c: In function ‘igb_get_invariants_82575’:
drivers/net/ethernet/intel/igb/e1000_82575.c:636:6: warning: this statement may fall through [-Wimplicit-fallthrough=]

case E1000_CTRL_EXT_LINK_MODE_PCIE_SERDES:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

Failed in read the HW register is very serious for igb/igc driver,
as its hw_addr will be set to NULL and cause the adapter be seen as
"REMOVED".
We saw the error only a few times in the MTBF test for suspend/resume,
but can hardly get any useful info to debug.
Adding WARN() so that we can get the necessary information about
where and how it happens, and use it for root causing and fixing
this "PCIe link lost issue"
This affects igb, igc.

Make sure only the portals for the online CPUs are used.
Without this change, there are issues when someone boots with
maxcpus=n, with n < actual number of cores available as frames
either received or corresponding to the transmit confirmation
path would be offered for dequeue to the offline CPU portals,
getting lost.

Make sure we don't use an out-of-bound index for the per-port RSS
context array.
As of today, the global context creation in mvpp22_rss_context_create
will prevent us from reaching this case, but we should still make sure
we are using a sane value anyway.
