d9a58a782e xen/netfront: improve truesize tracking
Using RX_COPY_THRESHOLD is incorrect if the SKB is actually smaller
than that. We have already accounted for this in
NETFRONT_SKB_CB(skb)->pull_to so use that instead.

Fixes WARN_ON from skb_try_coalesce.

9a6f7347f5 ath9k: Fix Kconfig for ATH9K_HTC
Ath9k consists of 2 different sub-modules: ATH9K and ATH9K_HTC.
Both uses common Atheros code from ath.ko and need ATH_COMMON.

However, while ATH9K selects ATH_COMMON, ATH9K_HTC does not.
As result, if ATH9K_HTC is the only Atheros card selected, compilation fails with
unresolved symbols.

This patch moves ATH_COMMON selection to the common part for both
ATH9K and ATH9K_HTC

7ffa592843 brcmsmac: Use udelay instead of usleep_range
wlc_lcnphy_rx_iq_cal_gain is called during initialization, i. e. when
executing brcms_up.
But brcms_up is called from brcms_ops_start while the latter holds a spin lock.
Thus, we cannot use usleep_range but have to use udelay.

This fixes:

6c653f6677 carl9170: fix -EINVAL bailout during init with !CONFIG_MAC80211_MESH
Sean reported that as of 3.7, his AR9170 device no longer works
because the driver fails during initialization. He noted this
is due to:
"In carl9170/fw.c, ar->hw->wiphy is tagged with
NL80211_IFTYPE_MESH_POINT support if the firmware has Content
after Beacon Queuing. This is both in interface_modes and the
only iface_combinations entry.

If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw
removes NL80211_IFTYPE_MESH_POINT from interface_modes, but
not iface_combinations.

wiphy_register then checks to see if every interface type in
every interface combination is in interface_modes.
NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON
warning and it returns -EINVAL, giving up."

Unfortunately, the iface_combination (types) feature bitmap
in ieee80211_iface_limit is part of a const member in the
ieee80211_iface_combination struct. Hence, the MESH_POINT
feature flag can't be masked by wiphy_register in the
same way as interface_modes in ieee80211_register_hw.

The socket calls from vxlan to join/leave multicast group aren't
using the index of the underlying device, as a result the stack uses
the first interface that is up. This results in vxlan being non functional

Fix this by providing the iflink field to the vxlan instance

793dad94e7 RDMA/cxgb4: Fix bug for active and passive LE hash collision path
Retries active opens for INUSE errors.

Logs any active ofld_connect_wr error replies.

Sends ofld_connect_wr on same ctrlq. It needs to go  on the same control txq as
regular CPL active/passive messages.

Retries on active open replies with EADDRINUSE.

Uses active open fw wr only if active filter region is set.

Adds stat for ofld_connect_wr failures.

This patch also adds debugfs file to show endpoints.

4945106d21 ksz884x: fix receive polling race condition
The ksz884x driver does receive processing in a custom tasklet, and
seems to be assuming that since it takes its private interface spinlock
with spin_lock_irq(), it won't be running concurrently with its own
interrupt handler, as it cannot be preempted by it, but since its
interrupt handler doesn't do any locking whatsoever, the receive
processing tasklet and interrupt handler can end up running concurrently
on different CPUs.

As a result of this, the ksz884x receive path ends up locking up fairly
easily, when the receive processing tasklet's reenabling of receive
interrupts (due to it being done with polling the receive ring) races
with the interrupt handler's disabling of receive interrupts (due to a
new receive interrupt coming in) resulting in the receive interrupt
being masked but the receive processing tasklet not being scheduled.

Fix this by making the ksz884x interrupt handler take its private
interface spinlock.  This requires upgrading the spin_lock() in the
transmit cleanup tasklet to a spin_lock_irq(), as otherwise the IRQ
handler can preempt transmit cleanup and deadlock the system, but
with those two changes, no more receive lockups have been observed.

log_num_mgm_entry_size to -1 (if the device actually supports flow

7b8157bedc mlx4_core: Adjustments to Flow Steering activation logic for SR-IOV
Separate flow steering capability detection from the decision to activate.

For the master (and for native), detect the flow steering capability
in mlx4_dev_cap, but activate the appropriate steering type in a new
function choose_flow_steering() based on detected data.

For VFs, activate flow steering based on what was actually activated
by the master, where that info is obtained via QUERY_HCA. This fixes
the current VF detection which is wrongly based on QUERY_DEV_CAP.

Also, for SR-IOV mode, if flow steering may be activated, do so only
if the max number of QPs per rule is sufficient to satisfy one
subscription per VF.  If not, fall back to B0 mode. This is needed to
serve registrations done by L2 network drivers such as mlx4_en and
IPoIB when the network stack attempts to join to multicast groups such
as all-hosts or the IPoIB broadcast group.

It divides filter region into regular filters and server filter portion. It
introduces new server filter region which will be exclusively used for creating
server filters. This region will not overlap with regular filter region.

It provides new API cxgb4_alloc_sftid in LLD for getting stid in case of LE
hash collision path. This new stid will be used to open server filter in the
filter region.
