Add support for Byte Queue Limits to the STMicro MAC driver.
Tested on a Amlogic S802 quad Cortex-A9 board, where the use of BQL
decreases the latency of a high priority ping from ~12ms to ~1ms when
the 100Mbit link is saturated by 20 TCP streams.

As removals can occur during resizes, entries may be referred to from
both tbl and future_tbl when the removal is requested. Therefore
rhashtable_remove() must unlink the entry in both tables if this is
the case. The existing code did search both tables but stopped when it
hit the first match.
Failing to unlink in both tables resulted in use after free.

IPv6 TCP sockets store in np->pktoptions skbs, and use skb_set_owner_r()
to charge the skb to socket.
It means that destructor must be called while socket is locked.
Therefore, we cannot use skb_get() or atomic_inc(&skb->users)
to protect ourselves : kfree_skb() might race with other users
manipulating sk->sk_forward_alloc
Fix this race by holding socket lock for the duration of
ip6_datagram_recv_ctl()

In commit 5a7baa78851b ("bonding: Advertize vxlan offload features when
supported"), Or Gerlitz added support conditional vxlan offload.
In this patch I also add support for all kind of tunnels,
but we allow a bonding device to not require segmentation,
as it is always better to make this segmentation at the very last stage,
if a particular slave device requires it.
Tested:
Setup a GRE tunnel,
on a physical NIC not having tx-gre-segmentation.
Results on bnx2x are even better, as we no longer have to segment
in software.

Static checkers complain that we should maybe set "ret" before we do the
"goto out;". They interpret the NULL return from br_port_get_rtnl() as
a failure and forgetting to set the error code is a common bug in this
situation.
The code is confusing but it's actually correct. We are returning zero
deliberately. Let's re-write it a bit to be more clear.

fixed_phy_set_link_update() contains an early check against a NULL
callback pointer, which basically prevents us from removing any
previous callback we may have set. The users of the fp->link_update
callback deal with a NULL callback just fine, so we really want to allow
"removing" a link_update callback to avoid dangling callback pointers
during e.g: module removal.

The kernel forcefully applies MTU values received in router
advertisements provided the new MTU is less than the current. This
behavior is undesirable when the user space is managing the MTU. Instead
a sysctl flag 'accept_ra_mtu' is introduced such that the user space
can control whether or not RA provided MTU updates should be applied. The
default behavior is unchanged; user space must explicitly set this flag
to 0 for RA MTUs to be ignored.

While doing further work on the fib_trie I noted a few items.
First I was using calls that were far more complicated than they needed to
be for determining when to push/pull the suffix length. I have updated the
code to reflect the simplier logic.
The second issue is that I realised we weren't necessarily handling the
case of a leaf_info struct surviving a flush. I have updated the logic so
that now we will call pull_suffix in the event of having a leaf info value
left in the leaf after flushing it.

This patch really does two things.
First it pulls the logic for determining if we should collapse one node out
of the tree and the actual code doing the collapse into a separate pair of
functions. This helps to make the changes to these areas more readable.
Second it encodes the upper 32b of the empty_children value onto the
full_children value in the case of bits == KEYLENGTH. By doing this we are
able to handle the case of a 32b node where empty_children would appear to
be 0 when it was actually 1ul << 32.

This change corrects an issue where if inflate or halve fails we were
exiting the resize function without at least updating the slen for the
node. To correct this I have moved the update of max_size into the while
loop so that it is only decremented on a successful call to either inflate
or halve.

This patch addresses two issues.
The first issue is the fact that I believe I had the RCU freeing sequence
slightly out of order. As a result we could get into an issue if a caller
went into a child of a child of the new node, then backtraced into the to be
freed parent, and then attempted to access a child of a child that may have
been consumed in a resize of one of the new nodes children. To resolve this I
have moved the resize after we have freed the oldtnode. The only side effect
of this is that we will now be calling resize on more nodes in the case of
inflate due to the fact that we don't have a good way to test to see if a
full_tnode on the new node was there before or after the allocation. This
should have minimal impact however since the node should already be
correctly size so it is just the cost of calling should_inflate that we
will be taking on the node which is only a couple of cycles.
The second issue is the fact that inflate and halve were essentially doing
the same thing after the new node was added to the trie replacing the old
one. As such it wasn't really necessary to keep the code in both functions
so I have split it out into two other functions, called replace and
update_children.

In doing performance testing and analysis of the changes I recently found
that by shifting the index I had created an unnecessary dependency.
I have updated the code so that we instead shift a mask by bits and then
just test against that as that should save us about 2 CPU cycles since we
can generate the mask while the key and pos are being processed.

When SRIOV commands are executed over the comm-channel and get
a fatal error (e.g. timeout, closing command failure) the VF enters
into error state and reset flow is activated.
To be able to recognize whether the failure was on a closing command, the
operational code for the given VHCR command is used. Once the device entered
into an error state we prevent redundant error messages from being printed.

In SRIOV, both the PF and the VF may attempt device recovery whenever they
assume that the device is not functioning. When the PF driver resets the
device, the VF should detect this and attempt to reinitialize itself.
The VF must be able to reset itself under all circumstances, even
if the PF is not responsive.
The VF shall reset itself in the following cases:
1. Commands are not processed within reasonable time over the communication channel.
This is done considering device state and the correct return code based on
the command as was done in the native mode, done in the next patch.
2. The VF driver receives an internal error event reported by the PF on the
communication channel. This occurs when the PF driver resets the device or
when VF is out of sync with the PF.
Add 'VF reset' capability, which allows the VF to reinitialize itself even when the
PF is not responsive.
As PF and VF may run their reset flow simulantanisly, there are several cases
that are handled:
- Prevent freeing VF resources upon FLR, when PF is in its unloading stage.
- Prevent PF getting VF commands before it has finished initializing its resources.
- Upon VF startup, check that comm-channel is online before sending
commands to the PF and getting timed-out.

We need to manage interface state to sync between reset flow and some other
relative cases such as remove_one. This has to be done to prevent certain
races. For example in case software stack is down as a result of unload call,
the remove_one should skip the unload phase.
Implement the remove_one case, handling AER and other cases comes next.
The interface can be up/down, upon remove_one, the state will include an extra
bit indicating that the device is cleaned-up, forcing other tasks to finish
before the final cleanup.

We activate reset flow upon command fatal errors, when the device enters an
erroneous state, and must be reset.
The cases below are assumed to be fatal: FW command timed-out, an error from FW
on closing commands, pci is offline when posting/pending a command.
In those cases we place the device into an error state: chip is reset, pending
commands are awakened and completed immediately. Subsequent commands will
return immediately.
The return code in the above cases will depend on the command. Commands which
free and close resources will return success (because the chip was reset, so
callers may safely free their kernel resources). Other commands will return -EIO.
Since the device's state was marked as error, the catas poller will
detect this and restart the device's software stack (as is done when a FW
internal error is directly detected). The device state is protected by a
persistent mutex lives on its mlx4_dev, as such no need any more for the
hcr_mutex which is removed.

This includes:
- resetting the chip when a fatal error is detected (the current code
does not do this).
- exposing the ability to enter error state from outside the catas code
by calling its functionality. (E.g. FW Command timeout, AER error).
- managing a persistent device state. This is needed to sync between
reset flow cases.

In the vxlan transmit path there is no need to reference the socket
for a tunnel which is needed for the receive side. We do, however,
need the vxlan_dev flags. This patch eliminate references
to the socket in the transmit path, and changes VXLAN_F_UNSHAREABLE
to be VXLAN_F_RCV_FLAGS. This mask is used to store the flags
applicable to receive (GBP, CSUM6_RX, and REMCSUM_RX) in the
vxlan_sock flags.

The UDP tunnel transmit functions udp_tunnel_xmit_skb and
udp_tunnel6_xmit_skb include a socket argument. The socket being
passed to the functions (from VXLAN) is a UDP created for receive
side. The only thing that the socket is used for in the transmit
functions is to get the setting for checksum (enabled or zero).
This patch removes the argument and and adds a nocheck argument
for checksum setting. This eliminates the unnecessary dependency
on a UDP socket for UDP tunnel transmit.

For SG or TSO, get one buffer descriptor and then unmap the related DMA memory, and then
get the next buffer descriptor, loop to while() to check "TX_READY". If "TX_READY" bit
still __IS__ existed in the BD (The next fraglist or next TSO packet is not transmited

above step with the same BD. The potential issue is that unmap the same DMA memory for

driver to use phy-supply devicetree property and the corresponding API, it cleans
the code a bit and make it simpler to maintain. This also replaces the property
phy_regulator by the standard property phy-supply in rk3288-evb-rk808.dts.

As these settings can be directly expressed from devicetree for both fixed
regulators and pmic-integrated regulators, it is more standard to set them
from dts and let the regulator framework use the right voltage informations
when it is used in the driver.

Always fully coalesce guest Rx packets into the minimum number of ring
slots. Reducing the number of slots per packet has significant
performance benefits when receiving off-host traffic.
Results from XenServer's performance benchmarks:
Baseline Full coalesce
Interhost VM receive 7.2 Gb/s 11 Gb/s
Interhost aggregate 24 Gb/s 24 Gb/s
Intrahost single stream 14 Gb/s 14 Gb/s
Intrahost aggregate 34 Gb/s 34 Gb/s
However, this can increase the number of grant ops per packet which
decreases performance of backend (dom0) to VM traffic (by ~10%)
/unless/ grant copy has been optimized for adjacent ops with the same
source or destination (see "grant-table: defer releasing pages
acquired in a grant copy"[1] expected in Xen 4.6).

Netlink FDB messages are sent in the link netns. The header of these messages
contains the ifindex (ndm_ifindex) of the netdevice, but this ifindex is
unusable in case of x-netns vxlan.
I named the new attribute NDA_NDM_IFINDEX_NETNSID, to avoid confusion with
NDA_IFINDEX.
