[Intel-wired-lan] [next PATCH S37 00/15] i40e/i40evf updates

[Bimmy Pujari]

Avinash Dayanand removes unnecessary code which caused supported link mode bug.

Catherine Sullivan adds a call to set the client interface down and fixes RSS
 to not be limited by the number of CPUs.

Greg Rose adds code to clean up MSIX irqs before suspend and save PCI state
before suspend.

Mitch Williams adds functions to clear default VSI, adds hw struct local
variable, writes HENA for VFs, reports RSS hash capability to stack, , fixes
buffer overflow problem by checking the address count and bailing out of the
loop at the appropriate time, adds code to activate correct MAC address filter
and sets default VSI without a reset

Serey Kong fixes missing DA cable check.

Shannon Nelson adds VSI info to macaddr messages.

Bimmy Pujari bumps version from 1.5.16 to 1.6.4.

[Intel-wired-lan] [next PATCH S37 01/15] i40e: add functions to control default VSI

[Bimmy Pujari]

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

Add functions to enable and disable default VSI on a VEB. This allows
for configuration of limited promiscuous mode specifically for bridging
purposes.

[Intel-wired-lan] [next PATCH S37 02/15] i40e: add hw struct local variable

[Bimmy Pujari]

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

This function uses the i40e_hw struct all over the place, so why doesn't
it keep a pointer to the struct? Add this pointer as a local variable
and use it consistently throughout the function.

If the user adds an obscene amount of MAC addresses, the driver will run
into the situation where it has too many address requests to fit into a
single PF message. The driver checks for this case, and calculates the
maximum number of messages that it can send. Then it completely ignores
this count and overflows the buffer.

Fix this by checking the address count and bailing out of the loop at
the appropriate time.

[Intel-wired-lan] [next PATCH S37 07/15] i40e: Clean up MSIX irqs before suspend

[Bimmy Pujari]

From: Greg Rose <gregory.v.rose@intel.com>

The i40e_suspend() function calls another function that preps the device
for the power save and resume by freeing all the tx/rx resources and
interrupts but that function does not free the "other" causes interrupt
vector and irq. It also fails to call synchronize_irq() before freeing
the irq vectors.  This sometimes may result in some AER errors on those
systems with that PCIe error reporting feature enabled.

Call synchronize_irq() before freeing irq vectors and explicitly free
the other causes interrupt resources and shut down that MSIX interrupt.

[Bimmy Pujari]

From: Catherine Sullivan <catherine.sullivan@intel.com>

Limiting qcount to pf->num_lan_msix, effectively limits the RSS queues
to only use the number of CPUs, and ignore all other queues. We don't
want to do this. If the user has changed the RSS settings to use more
queues then CPUS, we want to trust they know what they are doing and
let them. More importantly, if we tell them that is what we did, we want
to actually do it and allow traffic into all of the queues we have
allocated. This does not change the default setting to initially
allocate only the number of CPUS of queue pairs.

Always add MAC address at the tail of the MAC filter list. Since the
device's "real" MAC address is added first, it will always be at the
beginning of the list. This prevents an issue where the "real" MAC
filter might not get added if too many other filters are added before
bringing the interface up.

Real mac filter remains at top of filter list regardless of number of MACs added before bringing interface up, tools report hardware MAC

Bridges and entering/leaving promiscuous mode works correctly and does not trigger a reset
