Add constants and callback functions for the dwmac on rk3368 socs.
As can be seen, the base structure is the same, only registers and
the bits in them moved slightly.

The mac settings like RGMII/RMII, speeds etc are done in the so called
"General Register Files", contain numerous other settings as well and
always seem to change between Rockchip SoCs. Therefore abstract the
register accesses into a per-soc ops struct to make this reusable on
other Rockchip SoCs.

The first iteration of the dwmac-rk support did access an intermediate
clock directly below the pll selector. This was removed in a subsequent
revision, but the clock and one invocation remained. This results in
the driver trying to set the rate of a non-existent clock when the soc
and not some external source provides the phy clock for RMII phys.
So set the rate of the correct clock and remove the remaining now
completely unused definition.

Macvtap should be compatible with tuntap for
maximum number of queues.
commit 'baf71c5c1f80d82e92924050a60b5baaf97e3094 (tuntap:
Increase the number of queues in tun.)' removes
the limitations and increases number of queues in tuntap.
Now, Its safe to increase number of queues in Macvtap as well.
This patch also modifies 'macvtap_del_queues' function
to avoid extra memory allocation in stack.

Michael S. Tsirkin, Jason Wang :
Better way to use linked list to
avoid use of extra memory in stack.

Actor and Partner details can be accessed via proc-fs, sys-fs
entries or netlink interface. These interfaces are world readable
at this moment. The earlier patch-series made the LACP communication
secure to avoid nuisance attack from within the same L2 domain but
it did not prevent "someone unprivileged" looking at that information
on host and perform the same act.
This patch essentially avoids spitting those entries if the user
in question does not have enough privileges.

Netfilter updates for net-next
The following patchset contains a final Netfilter pull request for net-next
4.2. This mostly addresses some fallout from the previous pull request, small
netns updates and a couple of new features for nfnetlink_log and the socket
match that didn't get in time for the previous pull request. More specifically
they are:
1) Add security context information to nfnetlink_queue, from Roman Kubiak.
2) Add support to restore the sk_mark into skb->mark through xt_socket,
from Harout Hedeshian.
3) Force alignment of 16 bytes of per cpu xt_counters, from Eric Dumazet.
4) Rename br_netfilter.c to br_netfilter_hooks.c to prepare split of IPv6 code
into a separated file.
5) Move the IPv6 code in br_netfilter into a separated file.
6) Remove unused RCV_SKB_FAIL() in nfnetlink_queue and nfetlink_log, from Eric
Biederman.
7) Two liner to simplify netns logic in em_ipset_match().
8) Add missing includes to net/net_namespace.h to avoid compilation problems
that result from not including linux/netfilter.h in netns headers.
9) Use a forward declaration instead of including linux/proc_fs.h from
netns/netfilter.h
10) Add a new linux/netfilter_defs.h to replace the linux/netfilter.h inclusion
in netns headers.
11) Remove spurious netfilter.h file included in the net tree, also from Eric
Biederman.
12) Fix x_tables compilation warnings on 32 bits platforms that resulted from
recent changes in x_tables counters, from Florian Westphal.

====================
This series contains updates to fm10k only.
Alex provides two fixes for the fm10k, first folds the fm10k_pull_tail()
call into fm10k_add_rx_frag(), this way the fragment does not have to be
modified after it is added to the skb. The second fixes missing braces
to an if statement.
The remaining patches are from Jacob which contain improvements and fixes
for fm10k. First fix makes it so that invalid address will simply be
skipped and allows synchronizing the full list to proceed with using
iproute2 tool. Fixed a possible kernel panic by using the correct
transmit timestamp function. Simplified the code flow for setting the
IN_PROGRESS bit of the shinfo for an skb that we will be timestamping.
Fix a bug in the timestamping transmit enqueue code responsible for a
NULL pointer dereference and invalid access of the skb list by freeing
the clone in the cases where we did not add it to the queue. Update the
PF code so that it resets the empty TQMAP/RQMAP regirsters post-VFLR to
prevent innocent VF drivers from triggering malicious driver events.
The SYSTIME_CFG.Adjust direction bit is actually supposed to indicate
that the adjustment is positive, so fix the code to align correctly with
the hardware and documentation. Cleanup local variable that is no longer
used after a previous refactor of the code. Fix the code flow so that we
actually clear the enabled flag as part of our removal of the LPORT.

When a VF issues an LPORT_STATE request to enable a port that is already
enabled, the PF will first disable the VF LPORT. Then it should
re-enable the VF again with the new requested settings. This ensures
that any switch rules are cleared by deleting the LPORT on the switch.
However, the flow is bugged because we actually check if the VF is
enabled at the end, and thus don't re-enable it. Fix the flow so that we
actually clear the enabled flags as part of our removal of the LPORT.

During initialization, the VF counts its rings by walking the TQDLOC
registers. This works only if the TQMAP/RQMAP registers are set to map
all of the out-of-bound rings back to the first one. This allows the VF

that it resets the empty TQMAP/RQMAP registers post-VFLR to prevent
innocent VF drivers from triggering malicious driver events.

Currently, we don't notify the switch at all when the PF
administratively sets a new VLAN or MAC address. This causes the old
addresses to remain valid on the switch table. Since the PF is
overriding any configuration done directly by the VF, we choose to
simply re-create the LPORT for the VF. This does mean that all rules for
the VF will be dropped when we set something directly via the PF, but it
prevents some weird issues where the MAC/VLAN table retains some stale
configuration.

This patch cleans up the use of dma_get_required_mask and uses the
simpler dma_set_mask_and_coherent function instead of doing these as
separate steps.
I removed the dma_get_required_mask call because based on some minimal
testing it appears that either (a) we're not doing the right thing with
the call or (b) we don't need it anyways. If the value returned is
<48bits, we'll end up trying with 48 bits anyways. If it's over 48bits,
fm10k can't support that anyways, and we should try 48bits. If 48bits
fails, we'll fallback to 32bits. This cleans up some very funky code.
