[net-next 00/15][pull request] Intel Wired LAN Driver Updates 2014-06-08

[Jeff Kirsher]

This series contains updates to i40e and i40evf.

Jesse fixes an issue reported by Eric Dumazet where the driver was not
masking the right bits in the receive descriptor before checking them.
Also fixes TSO accounting since the kernel now can send as much as 32kB
in a single skb->frag[.] entry, even on a system with 4kB pages.

Anjali cleans up registers which are no longer supported.

Akeem cleans up code comments and removes num_msix_entries from the
interrupt setup routine since it was not being used.  Fixes an issue where
FD SB/ATR and NTUPLE configuration status were reported erroneously, so
now the driver reports FDir without further information.  Fixes a coding
error where during the registration for NAPI, the driver was requesting
256 budget.  The max recommended value for this NAPI_POLL_WEIGHT or 64.
Lastly, removed deprecated device IDs because they will not be shipped.

Mitch removes log messages which were redundant so therefore unnecessary.
Also removes a bogus code comment since VF drivers require MSI-X or they
won't get interrupts at all and cleans up the formatting of several log
messages.  Mitch also fixes the possibility of null pointers in VSI, since
not all VSIs have transmit rings.

Shannon ensures to clear the PXE mode bit on each reset after the AdminQ
has been rebuilt.

Catherine bumps the driver versions for i40e and i40evf.

The following are changes since commit fff1f59b1773fcbb563c503ad9c7ace54062144b:
  mac802154: llsec: add forgotten list_del_rcu in key removal

[net-next 01/15] i40e/i40evf: fix rx descriptor status

[Jeff Kirsher]

From: Jesse Brandeburg <jesse.brandeburg@intel.com>

As reported by Eric Dumazet, the driver is not masking the right
bits in the receive descriptor before it starts checking them.

This patch extends the mask to allow for the right bits to be
checked, and fixes the issue permanently via a define.

[net-next 03/15] i40e/i40evf: Clean up a few things

[Jeff Kirsher]

From: Akeem G Abodunrin <akeem.g.abodunrin@intel.com>

1. There is no ixgbe_watchdog_task function in the driver, so change
   the comment to the correct function name, i40e_watchdog_subtask.
2. Remove num_msix_entries from interrupt set_up routine
   because it is never used.
3. Remove some TBD comments that are not needed.

[net-next 04/15] i40evf: remove unnecessary log messages

[Jeff Kirsher]

From: Mitch Williams <mitch.a.williams@intel.com>

We don't need to print log messages when we encounter an out-of-memory
condition, as the allocator will do this for us. Also, remove a Tx hang
message that duplicates the one emitted by the netdev layer, and a
duplicate message in the watchdog.

A slightly associated trivial note:

One day it'd be nicer to use the same "if (!foo)"
test style everywhere.

[net-next 05/15] i40evf: remove bogus comment

[Jeff Kirsher]

From: Mitch Williams <mitch.a.williams@intel.com>

This comment is just plain false. VF drivers require MSI-X or they won't
get interrupts at all.

[net-next 06/15] i40evf: clean up log message formatting

[Jeff Kirsher]

From: Mitch Williams <mitch.a.williams@intel.com>

Clean up inconsistent log messages, mostly related to punctuation. Based
on the dogma that "kernel messages are not sentences", remove all
trailing periods. Reword a few of the messages to make them less
sentence-like.

[net-next 10/15] i40e: not all VSIs have rings

[Jeff Kirsher]

From: Mitch Williams <mitch.a.williams@intel.com>

Once more, with feeling: not all VSIs have rings. To assume so is to
invite null pointers to your party.

[net-next 11/15] i40e/i40evf: remove chatty reset messages

[Jeff Kirsher]

From: Mitch Williams <mitch.a.williams@intel.com>

Both the PF side and the VF side of the VF reset process are too noisy.
We already warn the user that a reset is happening, and that is
sufficient.

Because some of these message are inside if statements, we have to
rejigger the brackets at the same time to keep our coding style
consistent.

Unnecessary else, maybe simpler as

Thanks for your comments on these patches, Joe. I'm heading out for a three week vacation effective immediately, so I won't be getting to these comments right away. But "driver cleanup", including all of this stuff is on the top of my to-do list for when I get back.

[net-next 12/15] i40e/i40evf: fix TSO accounting

[Jeff Kirsher]

From: Jesse Brandeburg <jesse.brandeburg@intel.com>

The TSO logic in the transmit path had some assumptions that
have been broken now that the kernel can send as much as 32kB
in a single skb->frag[.] entry, even on a system with 4kB pages.

This fixes the assumptions and allows the kernel to operate
as efficiently as possible with both SENDFILE and SEND.

In addition, the hardware limit of data contained in a descriptor is
changed to the next power of two below where it currently is in
order to align to a power of two value, preventing a single byte
of data in a descriptor.

Re: [net-next 00/15][pull request] Intel Wired LAN Driver Updates 2014-06-08

Pulled, thanks Jeff.

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e and i40evf.

Jacob provides a i40e patch to remove ptp_tx_work() because it conflicts
with the interrupt-based handler and will cause spurious warning messages
to be displayed in the kernel log.  Since the hardware can properly trigger
an interrupt, we do not need to poll for an available timestamp in a work
queue any more.

Greg provides two patches for i40e, first to retain the MAC filter list
when changing a port VLAN.  Second fixes an issue where the function to
set the VF MAC address was not taking the port VLAN filter into account
when setting/clearing/resetting the VF's host administered MAC address.

Mitch provides three patches for i40evf, first adds support for getting
and setting RSS hashing options, RSS LUT entries, and getting the number
of device channels from ethtool.  Fixes a panic that woudl occur in the VF
if the PF driver failed or was removed from the host kernel.

Shannon adds driver version string to the driver version command so that
can be passed down through the firmware to low-level NC-SI functions.

Neerav provides several patches, first redistributes queue vectors after
DCB reconfiguration because the total number of queues that are configured
for a VSI may change based on a change in the total number of TCs enabled
as a result of a change in the DCB configuration based on DCBX.  Second,
allows the driver probe to continue when querying DCB config fails.
Lastly, provides changes to retrieve and store missing link config
information that was not being cached in the struct i40e_link_status.

Kevin provides a couple of patches, first to change a int variable type
to u16 to avoid a typecheck failure.  Second to update a function
parameters to remove an argument which is no longer used.

The following are changes since commit a49eb42a341f1df8fa0f9dc4449f9dd4a3234a2f:
  sched, act: allow to clear all actions as well
