Subject: ice: Do not configure port with no media

The firmware reports an error when trying to configure a port with no
media. Instead of always configuring the port, check for media before
attempting to configure it. In the absence of media, turn off link and
poll for media to become available before re-enabling link.

Move ice_force_phys_link_state() up to avoid forward declaration.

Subject: ice: Remove unnecessary flag ICE_FLAG_MSIX_ENA

This flag is not needed and is called every time we re-enable interrupts
in the hotpath so remove it. Also remove ice_vsi_req_irq() because it
was a wrapper function for ice_vsi_req_irq_msix() whose sole purpose was
checking the ICE_FLAG_MSIX_ENA flag.

Subject: ice: Restructure VFs initialization flows

This patch restructures how VFs are configured, and resources allocated.
Instead of freeing resources that were never allocated, and resetting
empty VFs that have never been created - the new flow will just allocate
resources for number of requested VFs based on the availability.

During VFs initialization process, global interrupt is disabled, and
rearmed after getting MSIX vectors for VFs. This allows immediate mailbox
communications, instead of delaying it till later and VFs.
PF communications resulted to using polling instead of actual interrupt.
The issue manifested when creating higher number of VFs (128 VFs) per PF.

Subject: ice: Increase size of Mailbox receive queue for many VFs

Currently we use the ICE_MBXQ_LEN for both the Mailbox send and receive
queues that are used to communicate with VFs. This is fine for the send
queue because the PF driver will lock the queue for every single send,
but for the Mailbox receive queue every VF is posting to its Mailbox
send queue and the hardware is then handing the message to the PF on its
Mailbox receive queue. This becomes a problem with many VFs because it
seems to overburden the Mailbox receive queue on the PF. Fix this by
increasing the Mailbox receive queue for the PF to 512 entries.

The number 512 was determined based on the number of VFs supported by
the device. We can have a total of 256 VFs so in the worst case this
allows the VFs to put 2 messages in the PFs Mailbox receive queue at the
same time.

Subject: ice: Move VF resources definition to SR-IOV specific file

In order to use some of the VF resources definition in the SR-IOV specific
virtchnl header file, this patch moves applicable code to
ice_virtchnl_pf.h file accordingly... and they should have been defined in
the destination file originally.

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.

Subject: ice: update ethtool stats on-demand

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.

Subject: ice: Alloc queue management bitmaps and arrays dynamically

The total number of queues available on the device is divided between
multiple physical functions (PF) in the firmware and provided to the
driver when it gets function capabilities from the firmware. Thus
each PF knows how many Tx/Rx queues it has. These queues are then
doled out to different VSIs (for LAN traffic, SR-IOV VF traffic, etc.)

To track usage of these queues at the PF level, the driver uses two
bitmaps avail_txqs and avail_rxqs. At the VSI level (i.e. struct ice_vsi
instances) the driver uses two arrays txq_map and rxq_map, to track
ownership of VSIs' queues in avail_txqs and avail_rxqs respectively.

The aforementioned bitmaps and arrays should be allocated dynamically,
because the number of queues supported by a PF is only available once
function capabilities have been queried. The current static allocation
consumes way more memory than required.

This patch removes the DECLARE_BITMAP for avail_txqs and avail_rxqs
and instead uses bitmap_zalloc to allocate the bitmaps during init.
Similarly txq_map and rxq_map are now allocated in ice_vsi_alloc_arrays.
As a result ICE_MAX_TXQS and ICE_MAX_RXQS defines are no longer needed.
Also as txq_map and rxq_map are now allocated and freed, some code
reordering was required in ice_vsi_rebuild for correct functioning.

Subject: ice: Add ice_get_main_vsi to get PF/main VSI

There are multiple places where we currently use ice_find_vsi_by_type
to get the PF (a.k.a. main) VSI. The PF VSI by definition is always
the first element in the pf->vsi array (i.e. pf->vsi[0]). So instead
add and use a new helper function ice_get_main_vsi, which just returns
pf->vsi[0].

Subject: ice: change work limit to a constant

The driver has supported a transmit work limit
that was configurable from ethtool for a long time, but
there are no good use cases for having it be a variable
that can be changed at run time.  In addition, this
variable was noted to be causing performance overhead
due to cache misses.

Just remove the variable and let the code use a constant
so that the functionality is maintained (a limit on the
number of transmits that will be cleaned in any one call
to the clean routines) without the cache miss.

Removes code, removes a variable, removes testing surface. Yay.

Subject: ice: Minor refactor in queue management

Remove q_left_tx and q_left_rx from the PF struct as these can be
obtained by calling ice_get_avail_txq_count and ice_get_avail_rxq_count
respectively.

The function ice_determine_q_usage is only setting num_lan_tx and
num_lan_rx in the PF structure, and these are later assigned to
vsi->alloc_txq and vsi->alloc_rxq respectively. This is an unnecessary
indirection, so remove ice_determine_q_usage and just assign values
for vsi->alloc_txq and vsi->alloc_rxq in ice_vsi_set_num_qs and use
these to set num_lan_tx and num_lan_rx respectively.

Subject: ice: change default number of receive descriptors

The driver should start out with a reasonable number of descriptors that
can prevent drops due to a CPU being in a power management state.
Change the default number of descriptors to 2048.
The user can always change the value at runtime.  Transmit descriptor
counts are not modified because they don't need to change due to the
speed of the interface, or for power managed CPUs, but the code is
simplified to a fixed value for the transmit default.

The driver is required to send a version to the firmware
to indicate that the driver is up. If the driver doesn't
do this the firmware doesn't behave properly.

The FW build id is currently being displayed as an int which doesn't make
sense. Instead display FW build id as a hex value. Also add other useful
information to the output such as NVM version, API patch info, and FW
build hash.

From 462acf6aca85cd4ee3e475f01240144c314f562c Mon Sep 17 00:00:00 2001
From: Tony Nguyen <anthony.l.nguyen@intel.com>
Date: Mon, 9 Sep 2019 06:47:46 -0700
Subject: ice: Enable DDP package download

Attempt to request an optional device-specific DDP package file
(one with the PCIe Device Serial Number in its name so that different DDP
package files can be used on different devices). If the optional package
file exists, download it to the device. If not, download the default
package file.

Log an appropriate message based on whether or not a DDP package
file exists and the return code from the attempt to download it to the
device.  If the download fails and there is not already a package file on
the device, go into "Safe Mode" where some features are not supported.
