During reboot or kexec, .shutdown is called, with the VFs probed to

net/mlx4_core: Fix SRIOV free-pool management when enforcing resource quotas
The Hypervisor driver tracks free slots and reserved slots at the global level
and tracks allocated slots and guaranteed slots per VF.
Guaranteed slots are treated as reserved by the driver, so the total
reserved slots is the sum of all guaranteed slots over all the VFs.
As VFs allocate resources, free (global) is decremented and allocated (per VF)
is incremented for those resources. However, reserved (global) is never changed.
This means that effectively, when a VF allocates a resource from its
guaranteed pool, it is actually reducing that resource's free pool (since
the global reserved count was not also reduced).
The fix for this problem is the following: For each resource, as long as a
VF's allocated count is <= its guaranteed number, when allocating for that
VF, the reserved count (global) should be reduced by the allocation as well.
When the global reserved count reaches zero, the remaining global free count
is still accessible as the free pool for that resource.
When the VF frees resources, the reverse happens: the global reserved count
for a resource is incremented only once the VFs allocated number falls below
its guaranteed number.

- BPF_X/BPF_K is 1 bit used to encode source operand of instruction
In classic:
BPF_X - means use register X as source operand

====================
bridge: multicast snooping patches / exports
The first patch is simply a cosmetic patch. So far I (and maybe others
too?) have been regularly confusing these two structs, therefore I'd
suggest renaming them and therefore making the follow-up patches easier
to understand and nicer to fit in.
The second patch fixes a minor issue, but probably not worth for stable.
On the other hand the first two patches are also preparations for the
third and fourth patch:
These two patches are exporting functionality needed to marry the bridge
multicast snooping with the batman-adv multicast optimizations recently
added for the 3.15 kernel, allowing to use these optimzations in common
setups having a bridge on top of e.g. bat0, too. So far these bridged
setups would fall back to simple flooding through the batman-adv mesh
network for any multicast packet entering bat0.

With this patch the bridge memorizes the source address of the currently

iw_cxgb4: Allocate and use IQs specifically for indirect interrupts
Currently indirect interrupts for RDMA CQs funnel through the LLD's RDMA
RXQs, which also handle direct interrupts for offload CPLs during RDMA
connection setup/teardown. The intended T4 usage model, however, is to
have indirect interrupts flow through dedicated IQs. IE not to mix
indirect interrupts with CPL messages in an IQ. This patch adds the
concept of RDMA concentrator IQs, or CIQs, setup and maintained by the
LLD and exported to iw_cxgb4 for use when creating CQs. RDMA CPLs will
flow through the LLD's RDMA RXQs, and CQ interrupts flow through the
CIQs.
Design:
cxgb4 creates and exports an array of CIQs for the RDMA ULD. These IQs
are sized according to the max available CQs available at adapter init.
In addition, these IQs don't need FL buffers since they only service
indirect interrupts. One CIQ is setup per RX channel similar to the
RDMA RXQs.
iw_cxgb4 will utilize these CIQs based on the vector value passed into
create_cq(). The num_comp_vectors advertised by iw_cxgb4 will be the
number of CIQs configured, and thus the vector value will be the index
into the array of CIQs.

Mitch adds code to allow for additional VSIs since the number of VSIs that
the firmware reports to us is a guaranteed minimum, not an absolute
maximum. The hardware actually supports for more than the reported value,
which we often need. Implements anti-spoofing for VFs for both MAC
addresses and VLANs, as well as enable this feature by default for all VFs.
Anjali changes the interrupt distribution policy to change the way
resources for special features are handled. Fixes the driver to not fall
back to one queue if the only feature enabled is ATR, since FD_SB
and FD_ATR need to be checked independently in order to decide if we
will support multiple queue or not. Allows the RSS table entry range
and GPS to be any number, not necessarily a power of 2 because hardware
does not restrict us to use a power of 2 GPS in the case of RSS as long as
we are not sharing the RSS table with another VSI (VMDq).
Frank modifies the driver to keep SR-IOV enabled in the case that RSS,
VMFq, FD_SB and DCB are disabled so that SR-IOV does not get turned off
unnecessarily.
Jesse fixes a bug in receive checksum where the driver was not marking
packets with bad checksums correctly, especially IPv6 packets with a bad
checksum. To do this correctly, we need a define that may be set by
hardware in rare cases.
Greg fixes the driver to delete all the old and stale MAC filters for the
VF VSI when the host administrator changes the VF MAC address from under
its feet.

Intel Wired LAN Driver Updates 2014-06-06
This series contains updates to i40e and i40evf.
Shannon sets the lan_veb index when the Virtual Ethernet Bridge (VEB) is
created for the basic LAN device and its Virtual Switch Interfaces (VSIs).
Also adds the VEB/VSI statistics in the ethtool stats output. Increases the
reset wait time because the original time was too optimistic and resets
were failing after EMPR. This won't delay the actual wait, just allows
us to poll more times as needed. He fixes the attempted removal of the
HMC space and unhook IRQs when a reset recovery fails because the HMC space
never got setup and IRQs are already unhooked in the first place, so the
removal is not necessary.
Jesse adds a log message for pre-production hardware so that the user is
notified that there may be issues with the hardware, yet does not prevent
the user from using the hardware. Add the printing of link messages
in the i40e driver like all the other Intel Ethernet drivers.
Mitch makes log message changes to i40evf to prevent confusion by making
the most common messages less scary by lowering them to a less terrifying
log level. This is due to the fact that depending on the timing of what
the PF driver is doing, it may take a few tries before the VF driver is able
to communicate with the PF driver on init or reset recovery.
Kamil provides a change to prevent the driver from getting into a endless
loop while trying to send GetVersion AQ command, since BO silicon blocks
AQ registers when in Blank Flash mode. So introduce a simple check for a
correct value in one of the AQ registers to be sure that AQ was configured
correctly.
Matt adds a function which indicates our intention to enable or disable a
particular transmit queue. Also adds a function to notify the device's
transmit unit that we are about to enable or disable a transmit queue.

If a reset recovery failed (e.g. firmware is broken), the HMC space won't
get set up. We don't need to try to delete it if it didn't get set up.
This stops some needless error messages when we already know we need to
just tear things down.
