Currently, a copy of the Rx packet header is copied into the the sk_buff
private data so that we can advance the pointer into the buffer,
potentially discarding the original. At the moment, this copy is held in
network byte order, but this means we're doing a lot of unnecessary
translations.
The reasons it was done this way are that we need the values in network
byte order occasionally and we can use the copy, slightly modified, as part
of an iov array when sending an ack or an abort packet.
However, it seems more reasonable on review that it would be better kept in
host byte order and that we make up a new header when we want to send
another packet.
To this end, rename the original header struct to rxrpc_wire_header (with
BE fields) and institute a variant called rxrpc_host_header that has host
order fields. Change the struct in the sk_buff private data into an
rxrpc_host_header and translate the values when filling it in.
This further allows us to keep values kept in various structures in host
byte order rather than network byte order and allows removal of some fields
that are byteswapped duplicates.

Since ezchip network driver is written with big endian EZChip platform it
is necessary to add support for little endian architecture.
The first issue is that the order of the bits in a bit field is
implementation specific. So all the bit fields are removed.
Named constants are used to access necessary fields.
And the second one is that network byte order is big endian.
For example, data on ethernet is transmitted with most-significant
octet (byte) first. So in case of little endian architecture
it is important to swap data byte order when we read it from
register. In case of unaligned access we can use "get_unaligned_be32"
and in other case we can use function "ioread32_rep" which reads all
data from register and works either with little endian or big endian
architecture.
And then when we are going to write data to register we need to restore
byte order using the function "put_unaligned_be32" in case of
unaligned access and in other case "iowrite32_rep".
The last little fix is a space between type and pointer to observe
coding style.

The new NET_DEVLINK infrastructure can be a loadable module, but the drivers
using it might be built-in, which causes link errors like:
drivers/net/built-in.o: In function `mlx4_load_one':
:(.text+0x2fbfda): undefined reference to `devlink_port_register'
:(.text+0x2fc084): undefined reference to `devlink_port_unregister'

:(.text+0x33a03a): undefined reference to `devlink_port_type_clear'
:(.text+0x33a04e): undefined reference to `devlink_port_unregister'
There are multiple ways to avoid this:
a) add 'depends on NET_DEVLINK || !NET_DEVLINK' dependencies
for each user
b) use 'select NET_DEVLINK' from each driver that uses it
and hide the symbol in Kconfig.
c) make NET_DEVLINK a 'bool' option so we don't have to
list it as a dependency, and rely on the APIs to be
stubbed out when it is disabled
d) use IS_REACHABLE() rather than IS_ENABLED() to check for
NET_DEVLINK in include/net/devlink.h
This implements a variation of approach a) by adding an
intermediate symbol that drivers can depend on, and changes
the three drivers using it.

It turns out that there are two large arrays on the stack here, but
almost all the data in them is never used outside of the loop in
which it gets written, so we can replace the array with a single

The .valid flag is used later, so I'm replacing the array of structures

to replace it with a bitmask and set_bit()/find_first_bit()/
find_last_bit()/... operations. However, I have not tested this patch,

stmmac: enhance driver performances and update the version
According to Giuseppe, I send the v3 series.
This is a subset of patches to rework the driver in order to improve its
performances and make it more robust under stress conditions.
All patches have been ported on STi mainstream kernel branch and
tested on ARM STiH4xx platforms and newer ones.
This series also updates the driver version and prepares it
to include further development to support new chips.
In detail, these patches are:
o to rework and improve the internal DMA bus settings
Fine tuning is mandatory on some platforms for both
performance and stability issues.
o to rework and optimize the descriptor management.
This will help a lot on performance side and preparing
the inclusion on the GMAC4.x.
o to add a set of optimizations for both xmit and rx functions.
These will help a lot on performance side and making the driver
more robust in case of low memory conditions and under some
stress test, performed for example on IP-STB.
Below some throughput figures obtained on some boxes before and after
the patches.

V2: - rx_copybreak is now managed by using ethtool.
V3: - improve comments on PCIe detailing that there are no regressions
- rework some APIs to properly define some params as bool as expected
- rework the formula to get the element inside the ring. Comparing V2,
patches 4 and 13 have been merged because the same formula have been
used. After this rework, no evident benefit has been noticed in terms
of performances so the table above is still valid. Disassembling the
code for SH4 and ARM, with the new formula just an instr is saved
(depending on compiler flags) and this gives us not so relevanti gain,
for example, on SH4 where some instr are executed in the same pipeline
stage.
Ring sizes are now fixed and maybe they can be reworked to be tuned
w/o using stmmaceth= cmdline option. Indeed, nobody change these sizes
and indeed the numbers selected by default respect the budget and
avoid to pass invalid setup. These are the best driver default sizes
for ring and chain.
