c1f570a6ab net: dsa: fix mii_bus to host_dev replacement
dsa_of_probe() still used cd->mii_bus instead of cd->host_dev when
building with CONFIG_OF=y. Fix this by making the replacement here as
well.

DSA Cleanups

This patch series does two things, first it cleans up the tag_protocol and
protocol ops being configured seperately.  Second it addresses the desire
to split DSA away from relying on a MII bus.

b4d2394d01 dsa: Replace mii_bus with a generic host device
This change makes it so that instead of passing and storing a mii_bus we
instead pass and store a host_dev.  From there we can test to determine the
exact type of device, and can verify it is the correct device for our switch.

So for example it would be possible to pass a device pointer from a pci_dev
and instead of checking for a PHY ID we could check for a vendor and/or device
ID.

5075314e4e dsa: Split ops up, and avoid assigning tag_protocol and receive separately
This change addresses several issues.

First, it was possible to set tag_protocol without setting the ops pointer.
To correct that I have reordered things so that rcv is now populated before
we set tag_protocol.

Second, it didn't make much sense to keep setting the device ops each time a
new slave was registered.  So by moving the receive portion out into root
switch initialization that issue should be addressed.

Third, I wanted to avoid sending tags if the rcv pointer was not registered
so I changed the tag check to verify if the rcv function pointer is set on
the root tree.  If it is then we start sending DSA tagged frames.

Finally I split the device ops pointer in the structures into two spots.  I
placed the rcv function pointer in the root switch since this makes it
easiest to access from there, and I placed the xmit function pointer in the
slave for the same reason.

====================
bonding: style, comment and assertion changes

This is a small and simple patch-set that doesn't introduce (hopefully) any
functional changes, but only stylistic and semantic ones.
Patch 01 simply uses the already provided __rlb_next_rx_slave function inside
rlb_next_rx_slave(), thus removing the duplication of code.
Patch 02 changes all comments that I could find to netdev style, removes
some outdated ones and fixes a few more small cosmetic issues (new line
after declaration, braces around if; else and such)
Patch 03 removes one extra ASSERT_RTNL() because we already have it in the
parent function and consolidates two other ASSERT_RTNL()s to the function
that is exported and supposed to be called with RTNL anyway.

First adjust a couple of locking comments that were left inaccurate,
then adjust comments to use the netdev styling and remove extra new
lines where necessary and add a couple of new lines between declarations
and code. These are all trivial styling changes, no functional change.
Also removed a couple of outdated or obvious comments.
This patch is by no means a complete fix of all netdev style violations
but it gets the bonding closer.

56924c3811 bonding: consolidate the two rlb_next_rx_slave functions into one
__rlb_next_rx_slave() is a copy of rlb_next_rx_slave() with the
difference that it uses rcu primitives to walk the slave list. We don't
need the two functions and can make rlb_next_rx_slave() a wrapper for
callers which hold RTNL.
So add a comment and ASSERT_RTNL() to make sure what is intended.

437024067a Merge branch 'tcpflags'
Eric Dumazet says:

====================
tcp: no longer keep around headers in input path

Looking at tcp_try_coalesce() I was wondering why I did :

if (tcp_hdr(from)->fin)
     return false;

The answer would be to allow the aggregation, if we simply OR the FIN and PSH
flags eventually present in @from to @to packet. (Note a change is also
needed in skb_try_coalesce() to avoid calling skb_put() with 0 len)

Then, looking at tcp_recvmsg(), I realized we access tcp_hdr(skb)->syn
(and maybe tcp_hdr(skb)->fin) for every packet we process from socket
receive queue.

We have to understand TCP flags are cold in cpu caches most of the time
(assuming TCP timestamps, and that application calls recvmsg() a long
time after incoming packet was processed), and bringing a whole
cache line only to access one bit is not very nice.

It would make sense to use in TCP input path TCP_SKB_CB(skb)->tcp_flags
as we do in output path.

This saves one cache line miss, and TCP tcp_collapse() can avoid dealing
with the headers.

e11ecddf51 tcp: use TCP_SKB_CB(skb)->tcp_flags in input path
Input path of TCP do not currently uses TCP_SKB_CB(skb)->tcp_flags,
which is only used in output path.

tcp_recvmsg(), looks at tcp_hdr(skb)->syn for every skb found in receive queue,
and its unfortunate because this bit is located in a cache line right before
the payload.

We can simplify TCP by copying tcp flags into TCP_SKB_CB(skb)->tcp_flags.

This patch does so, and avoids the cache line miss in tcp_recvmsg()

Following patches will
- allow a segment with FIN being coalesced in tcp_try_coalesce()
- simplify tcp_collapse() by not copying the headers.

	 For imx6sx, it alos is the clock source of interrupt coalescing.
	 The clock range: 200Mhz ~ 266Mhz.
clk_ref: refrence clock for tx and rx. For imx6sx enet RGMII mode,
	 the refrence clock is 125Mhz coming from internal PLL or external.
	 In i.MX6sx-arm2 board, the clock is from internal PLL.
	 clk_ref is optional, depends on board.
clk_enet_out: The clock can be output from internal PLL. It can supply 50Mhz
	 clock for phy. clk_enet_out is optional, depends on chip and board.
clk_ptp: 1588 ts clock. It is optional, depends on chip.

The patch add clk_ref to distiguish the different clocks.

0943629688 Merge branch 'be2net-next'
Sathya Perla says:

====================
be2net: patch set

Patch 1 fixes some minor issues with log messages in be2net.

Patch 2 replaces strcpy() calls with strlcpy() to avoid possible buffer
overflow.

Patch 3 improves the RX buffer posting scheme for jumbo frames.

Patch 4 replaces the use of v0 of SET_FLOW_CONTROL cmd with v1 to receive
a definitive completion status from FW.

Patch 5 adds support for ethtool "-m" ethtool option.

Patch 6 fixes port-type reporting via ethtool get_settings for QSFP/SFP+
interfaces.

Patch 7 fixes the usage of MODIFY_EQD FW cmd to target a max of 8 EQs on
Lancer chip.

Patch 8 enables PCIe error reporting even for VFs.

Pls consider applying this patch set to net-next. Thanks.

c30d72665c be2net: fix RX fragment posting for jumbo frames
In the RX path, the driver currently consumes upto 64 (budget) packets in
one NAPI sweep. When the size of the packet received is larger than a
fragment size (2K), more than one fragment is consumed for each packet.
As the driver currently posts a max of 64 fragments, all the consumed
fragments may not be replenished. This can cause avoidable drops in RX path.
This patch fixes this by posting a max(consumed_frags, 64) frags. This is
done only when there are atleast 64 free slots in the RXQ.

50762667f7 be2net: fix some log messages
This patch fixes the following minor issues with log messages in be2net:
  1) Period is not required at the end of log message.
  2) Remove "Unknown grp5 event" logs to reduce noise. The driver can safely
     ignore async events from FW it's not interested in.
  3) Reword a log message for better readability to say that SRIOV
     "is disabled" rather than "not supported".

233577a220 net: filter: constify detection of pkt_type_offset
Currently we have 2 pkt_type_offset functions doing the same thing and
spread across the architecture files. Remove those and replace them
with a PKT_TYPE_OFFSET macro helper which gets the constant value from a
zero sized sk_buff member right in front of the bitfield with offsetof.
This new offset marker does not change size of struct sk_buff.

ac7a04c33d net: dsa: change tag_protocol to an enum
Now that we introduced an additional multiplexing/demultiplexing layer
with commit 3e8a72d1da ("net: dsa: reduce number of protocol hooks")
that lives within the DSA code, we no longer need to have a given switch
driver tag_protocol be an actual ethertype value, instead, we can
replace it with an enum: dsa_tag_protocol.

Do this replacement in the drivers, which allows us to get rid of the
cpu_to_be16()/htons() dance, and remove ETH_P_BRCMTAG since we do not
need it anymore.
