[net-next 00/11][pull request] 100GbE Intel Wired LAN Driver Updates 2018-11-13

[Jeff Kirsher]

This series contains updates to the ice driver only.

Brett cleans up debug print messages by removing useless or duplicate
messages, and make sure we assign the hardware head pointer to head
instead of the software head pointer.  Resolved an issue when disabling
SRIOV we were trying to stop queues multiple times, so make sure we
disable SRIOV before stopping transmit and receive queues for VF.

Tony fixes a potential NULL pointer dereference during a VF reset.

Anirudh resolves an issue where we were releasing the VSI before
removing the VSI scheduler node, which was resulting in an error "Failed
to set LAN Tx queue context, error: -1".  Also fixed the guaranteed
number of VSIs available and used by discovering the device
capabilities to determine the 'guar_num_vsi' per function, rather than
always using the theoretical max number of VSIs every time.

Dave avoids a deadlock by nesting RTNL locking, so added a boolean to
determine if the RTNL lock is already held.

Lev fixes bad mask values which would break compilation.

Piotr increases the receive queue disable timeout since it can take
additional time to finish all pending queue requests.

Usha resolves an issue of VLAN priority tagged traffic not appearing on
all traffic classes, which was causing ETS bandwidth shaping to not work
as expected.

Henry fixes the reset path to cleanup the old scheduler tree before
rebuilding it.

Md Fahad removes a unnecessary check which was causing a driver load
error on platforms with more than 128 cores.

The following are changes since commit 3e536cff34244959c81575733c9ca60633f74e1b:
  net: phy: check if advertising is zero using linkmode_empty

[net-next 01/11] ice: Fix debug print in ice_tx_timeout

[Jeff Kirsher]

From: Brett Creeley <brett.creeley@intel.com>

Currently the debug print in ice_tx_timeout is printing useless and
duplicate values. First, head is being assigned to tx_ring->next_to_clean
and we are printing both of those values, but naming them HWB and NTC
respectively. Also, reading tail always returns 0 so remove that as well.

Instead of assigning the SW head (NTC) read to head, use the actual head
register and change the debug print to note that this is HW_HEAD. Also
reduce the scope of a couple variables.

[net-next 02/11] ice: Check for q_vector when stopping rings

[Jeff Kirsher]

From: Tony Nguyen <anthony.l.nguyen@intel.com>

There is a gap in time between a VF reset, which sets the q_vector to
NULL, and the VF requesting mapping of the q_vectors. If
ice_vsi_stop_tx_rings() is called during this time, a NULL pointer
dereference is encountered. Add a check in ice_vsi_stop_tx_rings()
to ensure the q_vector is set to avoid this situation from occurring.

[net-next 03/11] ice: Remove node before releasing VSI

[Jeff Kirsher]

From: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com>

Before releasing the VSI, remove the VSI scheduler node. If not,
the node is left in the scheduler tree and, on subsequent load, the
scheduler tree contains the node so it does not set it in vsi_ctx.
This, later, causes the node to not be found in ice_sched_get_free_qparent
which leads to a "Failed to set LAN Tx queue context, error: -1".

To remove the scheduler node, this patch introduces ice_rm_vsi_lan_cfg
and related helpers.

[net-next 04/11] ice: Calculate guaranteed VSIs per function and use it

[Jeff Kirsher]

From: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com>

Currently we are setting the guar_num_vsi to equal to ICE_MAX_VSI
which is the device limit of 768. This is incorrect and could have
unintended consequences. To fix this use the valid_function's 8-bit
bitmap returned from discovering device capabilities to determine the
guar_num_vsi per function. guar_num_vsi value is then passed on to
pf->num_alloc_vsi.

[net-next 05/11] ice: Avoid nested RTNL locking in ice_dis_vsi

[Jeff Kirsher]

From: Dave Ertman <david.m.ertman@intel.com>

ice_dis_vsi() performs an rtnl_lock() if it detects a netdev that is
running on the VSI. In cases where the RTNL lock has already been
acquired, a deadlock results. Add a boolean to pass to ice_dis_vsi to
tell it if the RTNL lock is already held.

[net-next 07/11] ice: Increase Rx queue disable timeout

[Jeff Kirsher]

From: Piotr Raczynski <piotr.raczynski@intel.com>

With much traffic coming into the port, Rx queue disable
procedure can take more time until all pending queue
requests on PCIe finish. Reuse ICE_Q_WAIT_MAX_RETRY macro
and increase the delay itself.

[net-next 08/11] ice: Call pci_disable_sriov before stopping queues for VF

[Jeff Kirsher]

From: Brett Creeley <brett.creeley@intel.com>

Previous to this commit the driver was immediately stopping Tx/Rx
queues when doing the following "echo 0 > sriov_numvfs" and then it was
calling pci_disable_sriov if the VFs are not assigned. This was causing
the VIRTCHNL_OP_DISABLE_QUEUES to fail because it was trying to stop
the queues for a second time.

Fix this by calling pci_disable_sriov before stopping the Tx/Rx queues.
This allows the VIRTCHNL_OP_DISABLE_QUEUES to get processed before the
driver tries to stop the Rx/Tx queues in ice_free_vfs.

[net-next 09/11] ice: Fix to make VLAN priority tagged traffic to appear on all TCs

[Jeff Kirsher]

From: Usha Ketineni <usha.k.ketineni@intel.com>

This patch includes below changes to resolve the issue of ETS bandwidth
shaping to work.

1. Allocation of Tx queues is accounted for based on the enabled TC's
   in ice_vsi_setup_q_map() and enabled the Tx queues on those TC's via
   ice_vsi_cfg_txqs()

2. Get the mapped netdev TC # for the user priority and set the priority
   to TC mapping for the VSI.

[net-next 10/11] ice: Destroy scheduler tree in reset path

[Jeff Kirsher]

From: Henry Tieman <henry.w.tieman@intel.com>

The scheduler tree is is always rebuilt during reset. The existing code
adds new scheduler nodes for queues but may not clean up earlier nodes.
This patch removed the old scheduler tree during reset before it is
rebuilt.

[net-next 11/11] ice: Remove ICE_MAX_TXQ_PER_TXQG check when configuring Tx queue

[Jeff Kirsher]

From: Md Fahad Iqbal Polash <md.fahad.iqbal.polash@intel.com>

This patch removes the condition checking of VSI TX queue number to
ICE_MAX_TXQ_PER_TXQG. This is an unnecessary check and causes a driver
load error on hosts that have more than 128 cores.
