From: David VomLehn <vomlehn@texas.net>
v1: Initial version
v2: o Make necessary drivers/net/ethernet changes to integrate software
o Drop intermediate atlantic directory
o Remove Makefile things only appropriate to out of tree module
building
v3: o Move changes to drivers/net/ethernet/{Kconfig,Makefile} to the last
patch to ensure clean bisection.
o Removed inline attribute aq_hw_write_req() as it was defined in
only one .c file.
o #included pci.h in aq_common.h to get struct pci definition.
o Modified code to unlock based execution flow rather than using a
flag.
o Made a number of functions that were only used in a single file
static.
o Cleaned up error and return code handling in various places.
o Remove AQ_CFG_IP_ALIGN definition.
o Other minor code clean up.
v4: o Using do_div for 64 bit division.
o Modified NIC statistics code.
o Using build_skb instead netdev_alloc_skb for single fragment
packets.
o Removed extra aq_nic.o from Makefile
v5: o Removed extra newline at the end of the files.
o Wrapped cover letter lines.

This patch should _really_ be the last in the series

Could you explain the basis for this? By convention, we put tables of
content at the beginning of books and only indices at the back.
Analogously, make and config files can be used to established the
context for what follows, making it easier to understand. Once
committed, of course, the order no longer matters except as bisection is
concerned.

You don't create the files until later patches.
If you applied just this first patch and tried to
add CONFIG_AQTION=y to the .config, make fails.
That's bad for git bisect.
Every patch in this series should build properly.
If you delay the adding of the Makefile and Kconfig
until all the files are added, then it'd bisect fine.

Please go back and re-read the latest patches; I think you will find
your concern about CONFIG_AQTION addressed in the v5 patchset. The 01/13
patch no longer has the changes to Makefile and Kconfig in
drivers/net/ethernet that will pull in the Makefile and Kconfig from
drivers/net/ethernet/aquantia. Those changes are now in the 13/13 patch,
which should make it bisectable. If I am missing something, please let
me know.

Well fine then.
I just looked subject titles and didn't notice that change.

Please don't hide multiple declarations and types inside of a macro,
that makes the code harder to understand.
Use a sub-structure or similar, and pass that sub-structure to the
handlers.

Please don't reinvent the wheel.
Use test_bit, set_bit, clear_bit, test_and_set_bit, and
test_and_clear_bit. Using an atomic_t for flag bits is completely
inappropriate, that type is primarily meant for atomic counters.
The appropriate type for *_bit() operations is "unsigned long".

Have not looked at the driver yet, but the threading of your emails is
weird, each patch is in reply to the previous one. It would be more
natural to have all numbered patches be in reply to the cover letter,
which according to the version of git you seem to have used (2.7.4)
should already be the default. In graphical terms what we see right now is:
[PATCH 00/13]
[PATCH 01/13]
[PATCH 02/13]
....
While we should see:
[PATCH 00/13]
[PATCH 01/13]
[PATCH 02/13]
....
Can you fix that for future submissions, this may sound like a cosmetic
thing, but it really helps with threading/reading etc.
Thanks!

Can you either use PHYLIB to interface to your PHY (which does all the
nice state machine management) or at the very least ethtool_op_get_link()?

Consider switching to the new ksettings API and filling in a bit more

Yoda notations are usually frowned upon. Instead of making this decision
here, can you push that down to the actual function reading the statistics?

You need to check that stringset == ETH_SS_STATS here since that's the
only thing you support. ethtool usually does not do it if the ioctl()
returning the data does not exist, but other bogus applications might.

The extern does not appear necessary here. Alternatively you may define
all the ethtool function pointers in this header file, but leave the
struct ethtool_ops in the main driver file which registers them at the
time of the netdev creation, up to you.

You should really try MSI(x) first and fallback to leagcy PCI INT# if
you cannot succeed, asking for a driver rebuild to switch between these
behaviors may not be an option for most people (a module parameter may
be an option but is usually not such a great idea).

That's not enough, you need to deal with Unicast address filtering,
promiscuous mode, and if you run out of space in your multicast address
filter.

That probably means nothing since it's the first time for the upstream
kernel that such a driver exists. Defining versions of software is such
an interesting subject anyway!

Few build warnings with W=1 (W=2 is just too verbose) that you may want
to fix, this was with GCC 4.8, newer compilers may flag new warnings as
well:
drivers/net/ethernet/aquantia/aq_main.c: In function
'aq_pci_probe_get_hw_ops_by_id':
drivers/net/ethernet/aquantia/aq_main.c:41:6: warning: variable 'err'
set but not used [-Wunused-but-set-variable]
int err = 0;
^
drivers/net/ethernet/aquantia/aq_main.c: In function 'aq_pci_remove':
drivers/net/ethernet/aquantia/aq_main.c:237:6: warning: variable 'err'
set but not used [-Wunused-but-set-variable]
int err = 0;

This looks like it is a consequence of setting the git configuration
item format.thread to deep. I've switched it to shallow, which should
give the threading you suggest.

You might want to create an aqtion or atlantic folder just in case you
later on submit a driver for another aquantia NIC. That would keep the
directory structure clean.

Yes, we did have it that way at one point. But...there is also the
kernel philosophy of not putting in something for future expansion; you
can always do it later... Honestly, I've vacillated on this particular one.

(please don't top post). There are several threads at the moment talking
about renaming driver directory (synopsys/stmmac, mlx5), doing it later
is certainly a possibility but is really frowned upon, since it will
later on make the life of people backporting -stable changes a lot harder.
Even if there is just one driver at the moment, I would go with a
dedicated directory for it, there are enough object files that justify
this choice IMHO.

About that top-posting...I agree, but Microsoft has the entire planet
doing it the other way. They find bottom posting confusing and often
can't even figure out that you replied. One more reason I've hated
Microsoft since 1976. So, I suspect I'm not the only one who
occasionally slips up. My apologies.

Good argument.

I think that the check that the passed MTU is at least 68 bytes is
justified and correct.
This convention is followed by a large number of Ethernet drivers; for example,
http://lxr.free-electrons.com/source/drivers/net/ethernet/intel/i40e/i40e_main.c#L2246
http://lxr.free-electrons.com/source/drivers/net/ethernet/intel/ixgbe/ixgbe_main.c#L6049
The size of 68 bytes is originated from RFC 791:
https://tools.ietf.org/html/rfc791
...
Every internet module must be able to forward a datagram of 68 octets
without further fragmentation.
This is because an internet header may be up to 60 octets, and the
minimum fragment is 8 octets.
...

Rami Rosen

Actually, the core will already impose min/max of ETH_MIN_MTU and
ETH_DATA_LEN. See
commit a52ad514fdf3b8a57ca4322c92d2d8d5c6182485

net: deprecate eth_change_mtu, remove usage
With centralized MTU checking, there's nothing productive done by
eth_change_mtu that isn't already done in dev_set_mtu, so mark it as
deprecated and remove all usage of it in the kernel. All callers have been
audited for calls to alloc_etherdev* or ether_setup directly, which means
they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu
prints out a netdev_warn about being deprecated, for the benefit of
out-of-tree drivers that might be utilizing it.
Of note, dvb_net.c actually had dev->mtu = 4096, while using
eth_change_mtu, meaning that if you ever tried changing it's mtu, you
couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set
to 4096 to remedy that.
