[Intel-wired-lan] [next PATCH S82 1/9] i40evf: Do not clear MSI-X PBA manually

[Alice Michael]

From: Alexander Duyck <alexander.h.duyck@intel.com>

We should not be clearing the pending bit array for each vector manually.
The documentation for the hardware states that when in MSI-X mode the
pending bit array wil be cleared automatically. Us clearing it ourselves
just results in multiple opportunities for us to drop an interrupt.

[Intel-wired-lan] [next PATCH S82 2/9] i40evf: Clean-up flags for promisc mode to avoid high polling rate

[Alice Michael]

From: Alexander Duyck <alexander.h.duyck@intel.com>

If you enabled and disabled promiscuous mode on a VF you could easily put
it into a state where it would start firing interrupts on all queues at a
rate of 50+ interrupts per second even though there was no traffic present.
The issue seems to have been a stray admin queue feature flag set that was
leaving us in a high polling rate for the adminq task.

[Intel-wired-lan] [next PATCH S82 3/9] i40evf: Drop i40evf_fire_sw_int as it is prone to races

[Alice Michael]

From: Alexander Duyck <alexander.h.duyck@intel.com>

Having the interrupts firing while we are polling causes extra overhead and
isn't needed for most systems out there. If an interrupt is lost us
experiencing a 2s latency spike before recovering is still not acceptable
and masks the issue. We are better off just identifying systems that lose
interrupts and instead enable workarounds for those systems.

To that end I am dropping the code that was strobing the interrupts as
there is a narrow window where having them enabled can actually cause
race issues anyway where a few stray packets might get misses if the
interrupt is re-enabled and fires before we call napi_complete.

Also replace one line where we were using bit 31 instead of the define
for the bit to represent masking the interrupt enable bit.

[Intel-wired-lan] [next PATCH S82 4/9] i40e: change ppp name to ddp

[Alice Michael]

From: Jingjing Wu <jingjing.wu@intel.com>

PPP name was going to be confusing since PPP already means point
to point protocol. It is decided to change pipeline personalization
profile(ppp) to dynamic device personalization(ddp).

[Intel-wired-lan] [next PATCH S82 5/9] i40e: track id can be 0

[Alice Michael]

From: Jingjing Wu <jingjing.wu@intel.com>

track_id == 0 is valid for ?read only? profiles when
profile does not have any ?write? commands.

[Intel-wired-lan] [next PATCH S82 6/9] i40e: Fix FLR reset timeout issue

[Alice Michael]

From: Filip Sadowski <filip.sadowski@intel.com>

This patch allows detection of upcoming core reset in case NIC gets
stuck while performing FLR reset. The i40e_pf_reset() function returns
I40E_ERR_NOT_READY when global reset was detected.

[Intel-wired-lan] [next PATCH S82 7/9] i40e: link_down_on_close private flag support

[Alice Michael]

From: Mariusz Stachura <mariusz.stachura@intel.com>

This patch introduces new ethtool private flag used for
forcing true link state. Function i40e_force_link_state that implements
this functionality was added, it sets phy_type = 0 in order to
work-around firmware's LESM. False positive error messages were
suppressed.

[Intel-wired-lan] [next PATCH S82 8/9] i40evf: fix client notify of l2 params

[Alice Michael]

From: Alan Brady <alan.brady@intel.com>

The current method for notifying clients of l2 parameters is broken
because we fail to copy the new parameters to the client instance
struct, we need to do the notification before the client 'open' function
pointer gets called, and lastly we should set the l2 parameters when
first adding a client instance.

This patch first introduces the i40evf_client_get_params function to
prevent code duplication in the i40evf_client_add_instance and the
i40evf_notify_client_l2_params functions.  We then fix the notify l2
params function to actually copy the parameters to client instance
struct and do the same in the *_add_instance' function.  Lastly this
patch reorganizes the priority in which client tasks fire so that if the
flag for notifying l2 params is set, it will trigger before the open
because the client needs these new parameters as part of a client open
task.

[Intel-wired-lan] [next PATCH S82 9/9] i40e: Suppress compilation warning on kernels older than 3.12

[Alice Michael]

From: Pawe? Jab?o?ski <pawel.jablonski@intel.com>

In kernels before 3.12 the second parameter in netif_set_xps_queue
function has no const qualifier. It is generating warning in older
kernels. get_cpu_mask function always returns a pointer with const
qualifier. Adding the cast is enough to remove compilation warning.

I don't think I see any code change for this comment... did this get 
stripped out?

And my first thought at seeing this message would be "so what?"  There 
needs to be something that says this request is getting skipped.

This patch is only for older kernels (where the driver is compiling form source on older systems). In newest ones is not needed.
