There are other kconfig symbols which use SCSI_FC_ATTRS.
In order to maintain sanity and prevent kconfig warnings, change
all of these from using 'select' to using 'depends on' so that
proper symbol dependencies will be honored and circular depends
problems will be avoided.
This fixes kconfig warnings and build errors:

Reported by Nikolay Aleksandrov.  In efx_init_port() we call
 efx_mac_reconfigure() to work around a Falcon/A1 limitation, and this calls
 efx_{arch}_filter_sync_rx_mode(), which takes the addr_list_lock; but this
 lock is uninitialised, because we haven't called register_netdevice() yet.
So, in efx_farch_filter_sync_rx_mode(), check efx_dev_registered() before
 doing anything else.
The EF10 equivalent, efx_ef10_filter_sync_rx_mode(), already has the
 corresponding check.

Just like CNIC bnx2i/bnx2fc also have their tristate dependent on IPV6, however
using the same solution as CNIC can cause recursive dependecies during make.

Based on suggestions by Randy Dunlap, SCSI_NETLINK now depends on NET instead

Just like CNIC, tristate of these two modules is also dependent on IPV6.
These need to be handled separately as they select CNIC, which can override
tristate for CNIC from 'm' to 'y', which can cause build failures when ipv6 is
 compiled as a module even if CNIC's Kconfig will only 'm' or 'n' when ipv6 is
compiled as a module.

====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Currently, it is possible to modify the vlan filter
configuration to add pvid or untagged support.
For example:
  bridge vlan add vid 10 dev eth0
  bridge vlan add vid 10 dev eth0 untagged pvid

The second statement will modify vlan 10 to
include untagged and pvid configuration.
However, it is currently impossible to go backwards
  bridge vlan add vid 10 dev eth0 untagged pvid
  bridge vlan add vid 10 dev eth0

Here nothing happens.  This patch correct this so
that any modifiers not supplied are removed from
the configuration.

The bridge code checks if vlan filtering is enabled on both
ingress and egress.   When the state flip happens, it
is possible for the bridge to currently be forwarding packets
and forwarding behavior becomes non-deterministic.  Bridge
may drop packets on some interfaces, but not others.

This patch solves this by caching the filtered state of the
packet into skb_cb on ingress.  The skb_cb is guaranteed to
not be over-written between the time packet entres bridge
forwarding path and the time it leaves it.  On egress, we
can then check the cached state to see if we need to
apply filtering information.

The problem is that the slave is first linked and slave_cnt is
incremented afterwards leading to a div by zero in the modes that use it
as a modulus. What happens is that in bond_start_xmit()
bond_has_slaves() is used to evaluate further transmission and it becomes
true after the slave is linked in, but when slave_cnt is used in the xmit
path it is still 0, so fetch it once and transmit based on that. Since
it is used only in round-robin and XOR modes, the fix is only for them.
Thanks to Eric Dumazet for pointing out the fault in my first try to fix
this.

management frames, this solves interrop issues.  Johannes has another
set of trivial fixes, while Luca fixes the way we configure the filters
in the firmware. Last but not least, a new device is added by Oren."

This patch changes the logic in tx path to ensure that tx descriptors

Signed-off-by: Beniamino Galvani <b.galvani@gmail.com>
Signed-off-by: David S. Miller <davem@davemloft.net>

In the current implementation the cleaning of tx ring is done by the
NAPI poll handler, which is scheduled after rx interrupts. Thus, in
absence of received packets the reclaim of used tx buffers is never
executed, blocking further transmission.

This can be easily reproduced starting the transmission of a UDP flow
with iperf, which blocks almost immediately because skbs are not
returned to the stack and the socket send buffer becomes full.

The patch enables tx interrupts so that the tx reclaim is scheduled
after completed transmissions.

This reverts commit 09ebb810.

ath9k_hw_set_sta_beacon_timers() configures AR_TIM_PERIOD with
the beacon interval. Before this commit, the sleepduration was
never greater than the beacon interval. But now, the behavior
has changed. For example, with an AP that uses a beacon interval of 100:

ath: phy9: next beacon 61128704
ath: phy9: beacon period 204800
ath: phy9: DTIM period 204800

If the sleepduration is calculated based on the listen time, then
the bmiss threshold should also be changed since the HW would
be in sleep state for a longer time, but that is not done currently.

To avoid configuring a higher beacon interval based on the sleepduration,
revert to the original behavior. Power consumption is not a
problem since PS is disabled in ath9k anyway.

We wrongly tested QP context bits without BE conversion
as was spotted by sparse...

drivers/infiniband/hw/mlx4/qp.c:1685:38: sparse: restricted __be32 degrades to integer

Fix that!

Changing the vlan stripping policy of the QP isn't supported by older
firmware versions for the INIT2RTR command. Nevertheless, we've used it.

Fix that by doing this policy change using INIT2RTR only if the firmware
supports it, otherwise, we call UPDATE_QP command to do the task.

The current wrapper implementation of the UPDATE_QP command tries to get
the MAC index, even if MAC wasn't set by the VF. Fix it up to only handle
the MAC field if it's valid.

When doing VGT->VST->VGT state changes, we used an incorrect mask
for the vlan-stripping-disable (VSD) flag, hence the vlan related policy
for user-space Raw Ethernet QPs open by VFs wasn't really applied.

Fix that, by using the correct mask.

Single port VFs are seen PCI wise on both ports of the PF (we don't have
single port PFs with ConnectX). With this in mind, it's possible for
virtualization tools to try and configure a single ported VF through
the "wrong" PF port.

To handle that, we use the PF driver mapping of single port VFs to NIC
ports and adjust the port value before calling into the low level
code that does the actual VF configuration
