The mv88e6xxx.h is meant to contains the chip structures and data.
Rename it to chip.h, as for other source/header pairs of the driver.
At the same time, ensure that relative header inclusions are separated

There was no reason for duplicating the code that initializes
ds->enabled_port_mask in both dsa_parse_ports_dn() and
dsa_parse_ports(), instead move this to dsa_ds_parse() which is early
enough before ops->setup() has run.
While at it, we can now make dsa_is_cpu_port() check ds->cpu_port_mask
which is a step towards being multi-CPU port capable.

We do not need to have a reference to a dsa_switch, instead we should

DCCP uses dccp_write_space() for sk->sk_write_space method.
Unfortunately a passive connection (as provided by accept())
is using the generic sk_stream_write_space() function.
Lets simply inherit sk->sk_write_space from the parent
instead of forcing the generic one.

If any errors are encountered while walking the device tree structure of
the MDIO bus for children, the code may silently continue, silently
exit, or throw an error and exit. This make it difficult for device
tree writers to know there is an error. Also, it makes any error in a
child entry of the MDIO bus be fatal for all entries. Instead, we
should provide verbose errors describing the error and then attempt to
continue if it all possible. Also, use of_mdio_parse_addr()

Currently when a data packet is retransmitted, we do not compute an
RTT sample for congestion control due to Kern's check. Therefore the
congestion control that uses RTT signals may not receive any update
during loss recovery which could last many round trips. For example,
BBR and Vegas may not be able to update its min RTT estimation if the
network path has shortened until it recovers from losses. This patch
mitigates that by using TCP timestamp options for RTT measurement
for congestion control. Note that we already use timestamps for
RTT estimation.

Since last patch, sctp doesn't need to alloc memory for asoc->stream any
more. sctp_stream_new and sctp_stream_init both are used to alloc memory
for stream.in or stream.out, and their names are also confusing.
This patch is to merge them into sctp_stream_init, and only pass stream
and streamcnt parameters into it, instead of the whole asoc.

As Marcelo's suggestion, stream is a fixed size member of asoc and would
not grow with more streams. To avoid an allocation for it, this patch is
to define it as an object instead of pointer and update the places using
it, also create sctp_stream_update() called in sctp_assoc_update() to
migrate the stream info from one stream to another.

40GbE Intel Wired LAN Driver Updates 2017-06-01
This series contains updates to i40e, i40evf and the "new" AVF virtchnl.
This is the introduction of the Intel(R) Ethernet Adaptive Virtual
Function driver code and device ID, as presented at the NetDEV 1.2
conference in 2016.
http://netdevconf.org/1.2/session.html?anjali-singhai
The idea is to convert the interface between the i40evf driver
and the parent i40e PF driver to be generic, as the i40evf driver
should in the future be able to run on top of other Intel PF
drivers, and negotiate any features beyond a "base expected" set.
