[net-next v2 00/17][pull request] Intel Wired LAN Driver Updates 2015-01-16

[Jeff Kirsher]

This series contains updates to i40e and i40evf.

This series is a little bit larger than normal because two of the patches are
version bumps.

Shannon provides tweaks to i40e and i40evf to keep the firmware, software
and silicon validation in line together by removing unused and
deprecated code, adding define for iSCSI and fix queue mask size.  Fix
i40e so we do not give up in the reset/rebuild process if DCB setup
fails, just handle it the same as in the probe setup.  Cleans up PTP
log messages by removing the use of __func__ as we are not using that
any longer and removes the netdev name, since that can change and can
be misleading.  Adds struct size checks to indirect and command
structs that were left out previously.  Added admin queue API updates
(LLDP control, OEM OCSD and OCBB commands).

Kevin increases ASQ timeout for scenarios with multi-function devices.

Carolyn fixes a problem where the interrupts descriptions from the MSIx
configuration were truncating the needed bus info, which makes it hard
to distinguish configurations from port to port.  Increased the string
buffer size in order to allow the full data to be displayed.

Sravanthi cleans up the dump stats string from debugfs.

Jacob updates i40e to only enable the PTP interrupt in PFs which have PTP
enabled, instead of blindly enabling the PTP interrupt flags for all PFs.
Also updated i40e so that we do not do Tx or Rx timestamps if we do not
have PTP enabled.  Added the same check against pf->ptp_rx as we have
in Rx timestamp code path because it is possible that the user can
configure only Tx hardware timestamping so we do not want to check for
Rx timestamp hang since the software won't be handling them.

Neerav updates the driver to disable firmware LLDP agent for NICs with
a firmware version lower than v4.3 and added a message when this happens.
Adds parsing and reporting of iSCSI capability for a given device or
function, as well as adding support for iSCSI partition type with DCB
in NPAR mode.

v2:
 - Dropped patch 10 "i40e: clean up PTP log messages" based on feedback
   from David Laight and David Miller
 - Split up the original patch 13 "i40e: AQ API updates for new commands"
   into 2 patches (now #12 & #13) based on feedback from Or Gerlitz

The following are changes since commit 919d9db9521862d01712d9be25cd6ebfcc353eed:

[net-next v2 01/17] i40e/i40evf: AdminQ updates ww36

[Jeff Kirsher]

From: Shannon Nelson <shannon.nelson@intel.com>

Several little tweaks to keep FW, SV, and SW in line together
 - Remove the unused and deprecated
   i40e_aqc_opc_debug_modify_internals
 - Add define for iSCSI capability
 - Fix queue mask size
 - Adjust i40e_aqc_oem_param_change for ease-of-use

[net-next v2 03/17] i40e: fix proc/int descriptions

[Jeff Kirsher]

From: Carolyn Wyborny <carolyn.wyborny@intel.com>

This patch fixes a problem where the /proc/interrupts descriptions
from the msix configuration were truncating the needed bus info,
making it hard to distinguish configuration from port to port.
This patch increases the string buffer size in order to allow the
full data to be displayed and sync's the text formatting of the misc
and fdir interrupt names

[net-next v2 04/17] i40e: don't give up on DCB error after reset

[Jeff Kirsher]

From: Shannon Nelson <shannon.nelson@intel.com>

We don't need to give up in the reset/rebuild process if the DCB setup failed,
so handle it here the same as in the probe setup.  Also adjust the log strings
a little to look less scary.

From: Sravanthi Tangeda <sravanthi.tangeda@intel.com>

Dump Stats string has been removed from functional debugfs
help message. Now it does not show up when we echo command to
debugfs/Fortville queue.

We should not blindly enable the PTP interrupt flags for all PFs. We
should only enable the PTP interrupt in PFs which have enabled
PTP.

[net-next v2 09/17] i40e: check I40E_FLAG_PTP before handling Tx or Rx timestamps

[Jeff Kirsher]

From: Jacob Keller <jacob.e.keller@intel.com>

We should not be doing Tx or Rx timestamps if we do not have PTP
enabled. Add checks to ensure that we don't attempt to handle any PTP
related timestamping code if we have not enabled PTP on that PF.

[net-next v2 14/17] i40e: use same check for Rx hang as for Rx timestamps

[Jeff Kirsher]

From: Jacob Keller <jacob.e.keller@intel.com>

It's possible that the user configured only Tx hardware timestamping,
and thus we might be receiving PTP traffic which we timestamp but which
software never reads. In this case we don't want to check for Rx
timestamp hang, because we already know that software won't be handling
them. Thus, we add the same check against pf->ptp_rx as we have in the
Rx timestamp code path.

[net-next v2 15/17] i40e: when Rx timestamps disabled set specific mode

[Jeff Kirsher]

From: Jacob Keller <jacob.e.keller@intel.com>

Instead of leaving the Rx timestamps in the same mode as before if we
disable the Rx logic, we can set it into a mode that has the fewest
possible timestamps generated. To do this, select only V1 mode, but do
not enable UDP packet recognition. This should eliminate all (or at
least almost all) Rx timestamps, since V1 packets are always over UDP.

[net-next v2 16/17] i40e: Support for NPAR iSCSI partition with DCB

[Jeff Kirsher]

From: Neerav Parikh <neerav.parikh@intel.com>

Add parsing and reporting of iSCSI capability for a given device or
function.

Also add support for iSCSI partition type with DCB in NPAR mode.
In this mode it is expected that software would configure both the LAN
and iSCSI traffic classes for the iSCSI partition; whereas all the NIC
type partitions will use LAN TC (TC0) only.
Hence, the patch enables querying of DCB configuration in MFP mode and
configures TCs for iSCSI partition type.

Though NIC type partitions may not have more than 1 TC enabled for them
the port may have multiple TCs enabled and hence I40E_FLAG_DCB_ENABLED
will be set/reset on all the partitions based on number of TCs on the
port. This is required as in DCB environment it is expected that all
traffic will be priority tagged.
