Initially the phy_bus_name was added to manipulate the
driver name but it was recently just used to manage the
fixed-link and then to take some decision at run-time.
So the patch uses the is_pseudo_fixed_link and removes
the phy_bus_name variable not necessary anymore.
The driver can manage the mdio registration by using phy-handle,
dwmac-mdio and own parameter e.g. snps,phy-addr.
This patch takes care about all these possible configurations
and fixes the mdio registration in case of there is a real
transceiver or a switch (that needs to be managed by using
fixed-link).

Intel Wired LAN Driver Updates 2016-03-29
This series contains fixes to ixgbe and ixgbevf.
Tushar fixes an issue which was introduced with an earlier commit, where
hardware register RAR0 default MAC address does not get set properly.
Alex fixes two issues, first being the VXLAN port number should be stored
in network order instead of in host order. The second fix corrects the ATR
code to handle IPv6 extension headers. The issue was ATR code was assuming
that it would be able to use tcp_hdr for every TCP frame that came through,
but that is not the case, which resulted in bad filters being setup.
Mark fixes a use of usleep_range() to udelay() in the case where a lock
is being held.
Stefan fixes the offline self tests where ndo_stop() should be used instead
of ndo_close(), which causes IFF_UP to be cleared and interface routes get
removed.
Emil fixes the error case where we need to return an error when a MAC
address change is rejected by the PF. This helps prevent the user from
modifying the MAC address when the operation is not permitted.
Sridhar provides three fixes for ixgbe, all dealing with traffic class
offload handling.

The ATR code was assuming that it would be able to use tcp_hdr for
every TCP frame that came through. However this isn't the case as it
is possible for a frame to arrive that is TCP but sent through something
like a raw socket. As a result the driver was setting up bad filters in
which tcp_hdr was really pointing to the network header so the data was
all invalid.
In order to correct this I have added a bit of parsing logic that will
determine the TCP header location based off of the network header and
either the offset in the case of the IPv4 header, or a walk through the
IPv6 extension headers until it encounters the header that indicates
IPPROTO_TCP. In addition I have added checks to verify that the lowest
protocol provided is recognized as IPv4 or IPv6 to help mitigate raw
sockets using ETH_P_ALL from having ATR applied to them.

The VXLAN port number should be stored in network order instead of in host
order as it is accessed from the hot-path in ATR. This way we can avoid
having to do any byte swaps in order to validate the port number.
I moved the vxlan_port value into a hole in the read-mostly region of the
adapter struct. This way it should be in a warm cache-line instead of in
some isolated region in memory when it needs to be accessed.
In addition I went through and stripped a bunch of unneeded ifdef flags
since having an extra variable present doesn't really hurt anything and
makes the code easier to read. I also went through and dropped the
NETIF_F_RXCSUM flag which was being set in hw_encap_features but provides
no value as the flag is not evaluated in the Rx path.

skb_len needs to be skb_headlen(skb) in bcmgenet_xmit_single().
Fragmented skbs can have only Ethernet + IP + TCP headers (14+20+20=54 bytes)
in the linear buffer, followed by the rest in fragments. Bumping skb_len to
ETH_ZLEN would be incorrect for this case, as it would introduce garbage
between TCP header and the fragment data.
This also works with regular/non-fragmented small packets < ETH_ZLEN bytes.
Successfully tested this on GENETv3 with 42-byte ARP frames.
For testing, I used:
ethtool -K eth0 tx-checksum-ipv4 off
ethtool -K eth0 tx-checksum-ipv6 off

1. Add bytes_compl local variable to __bcmgenet_tx_reclaim() to collect

2. When bcmgenet device uses Tx checksum offload, each transmitted skb
gets an extra 64-byte header prepended to it. Before this header is
prepended to the skb, we need to save the skb "wire" length in
GENET_CB(skb)->bytes_sent, so that proper Tx bytes accounting can
be done in __bcmgenet_tx_reclaim().
3. skb->len covers the entire length of skb, whether it is linear or
fragmented. Thus, when we clean the fragments, do not increase
transmitted bytes.

- A few minor core fixups needed for the next patch series
- The IB SRIOV series. This has bounced around for several versions.
Of note is the fact that the first patch in this series effects
the net core. It was directed to netdev and DaveM for each iteration
of the series (three versions total). Dave did not object, but did
not respond either. I've taken this as permission to move forward
with the series.
- The new Intel X722 iWARP driver
- A huge set of updates to the Intel hfi1 driver. Of particular interest
here is that we have left the driver in staging since it still has an
API that people object to. Intel is working on a fix, but getting
these patches in now helps keep me sane as the upstream and Intel's
trees were over 300 patches apart.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull more rdma updates from Doug Ledford:
"Round two of 4.6 merge window patches.
This is a monster pull request. I held off on the hfi1 driver updates
(the hfi1 driver is intimately tied to the qib driver and the new
rdmavt software library that was created to help both of them) in my
first pull request. The hfi1/qib/rdmavt update is probably 90% of
this pull request. The hfi1 driver is being left in staging so that
it can be fixed up in regards to the API that Al and yourself didn't
like. Intel has agreed to do the work, but in the meantime, this
clears out 300+ patches in the backlog queue and brings my tree and
their tree closer to sync.
This also includes about 10 patches to the core and a few to mlx5 to
create an infrastructure for configuring SRIOV ports on IB devices.
That series includes one patch to the net core that we sent to netdev@
and Dave Miller with each of the three revisions to the series. We
didn't get any response to the patch, so we took that as implicit
approval.
Finally, this series includes Intel's new iWARP driver for their x722
cards. It's not nearly the beast as the hfi1 driver. It also has a
linux-next merge issue, but that has been resolved and it now passes
just fine.
Summary:
- A few minor core fixups needed for the next patch series
- The IB SRIOV series. This has bounced around for several versions.
Of note is the fact that the first patch in this series effects the

The driver calls gpiod_set_value() with GPIOD_OUT_* instead of 0 and 1, as
a result the PHY isn't really put back into reset state in macb_remove().
Moreover, the driver assumes that something else has set the GPIO direction
to output, so if it has not, the PHY may not be taken out of reset in
macb_probe() either...

Errata A-007273 (For FMan V3 devices only):
FMan soft reset is not finished properly if one
of the Ethernet MAC clocks is disabled
Workaround:
Re-enable all disabled MAC clocks through the DCFG_CCSR_DEVDISR2
register prior to issuing an FMAN soft reset.
Re-disable the MAC clocks after the FMAN soft reset is done.
