* [PATCH] ARM: dts: at91: VInCo: fix phy reset gpio flag

Fix gpio active flag for the phy reset-gpios property. The line is
active low instead of active high.
Actually, this flags was never used by the macb driver.

Hi,
Thanks for having reported this bug to me.
I hope that we will be able to move forward for changing the phy
reset code in the macb driver.
I plan to queue this patch through arm-soc for 4.7.
Thanks, best regards,
Nicolas

Well, who defines "correctly"? :-)
I can do that, it really doesn't matter. One way or the other, the
result will be the same. I'll move this to iproute2 in v3.

Thinking about this more, this *is* uAPI breakage and we can't do that.
It affects also gretap and current users of gretap lwtunnels would be
broken. This is even more likely as it's not possible to create gretap
lwtunnel using iproute2 without specifying a fake remote address.
In theory, we could wrap the current ipgre_tunnel_validate with a new
function that would be set as ipgre_link_ops->validate but that would
add unnecessary complexity and would make ipgre and gretap behavior
different.
I'm sorry, we have to live with what we have. This should have been
taken into account when you implemented lwtunnels for GRE, we can't
change this now, it's too late.
I'll send v3 with this patch being restored to exactly what I had in v1.

In-Reply-To: <20160425205650.GA31129@lunn.ch>
Hi Andrew,
Thanks for reviewing. I really appreciate your effort it.
I am already aware of MDIO mux framework but did not see it fit for our
use case due to below limitations:
1. Current MDIO mux framework is Ethernet centric and it is only meant to
mux multiple MII buses using same MDIO controller. This means it is only
meant for MII-compliant PHY devices (i.e. PHY devices having registers
as-per MII specs). This is not the case with Broadcom SATA PHYs, PCIe
PHYs, and USB PHYs even if we are sharing same MDIO controller for
accessing these PHYs.
2. The MDIO mux framework registers each child bus as MII bus. The Linux
Ethernet MDIO framework will scan for all attached PHY devices on given
MII bus and try to read MII PHY_ID register which is not present in all
Broadcom non-ethernet PHYs.
3. Let's say we ignore point1 and point2 above and go ahead and use MDIO
mux framework then we will still have to emulated MII PHY_ID read for
non-ethernet PHYs. Let's say we also emulate MII PHY_ID read in
non-ethernet PHYs then next thing is non-ethernet PHYs don't follow MII
state machine so all other MII PHY register read/write will not work.
4. Apart from these, by using MDIO mux framework we are making our
non-ethernet PHYs dependent on Linux network drivers which is not
acceptable. What if some product line does not need network subsystem at
all?
As you can see from above points, trying to re-use Linux Ethernet MDIO mux
framework for non-Ethernet PHYs is not the right way. The sole reason
being Linux MDIO mux framework is not generic enough to be shared across
IO subsystems. Due to this reason we had to come-up with "Shared MDIO
framework" which is very simple, generic and independent of I/O
subsystems.
I'll add PCIe PHYs driver based on Shared MDIO framework in next patch
revision to get a feel of its need.
Regards,
Pramod

I also fix the value of INET_DIAG_MAX. It's wrong since commit 8f840e47f190
which is only in net-next right now, thus I didn't make a separate patch.
Fixes: 8f840e47f190 ("sctp: add the sctp_diag.c file")

This is the continuation (series #3) of the work done to align netlink
attributes when these attributes contain some 64-bit fields.
It's the last patchset from what I've seen.
The last user of nla_put_u64() is block/drbd. This module does not use
standard netlink API (see all the stuff in include/linux/genl_magic_struct.h
and include/linux/genl_magic_func.h). I didn't modify it because it's seems
hard to do it whithout testing and fully understanding the context (for
example, why include/linux/drbd_genl.h is not part of uapi?).
Any thoughts?

Sounds reasonable for me.

Hi Nicholas,
Thanks for doing this.
I'll also add a fix for the macro-generated nla_put_64() in
nl80211_send_station(), unless there was a particular reason you didn't
take that one?
I suspect you just missed it while grepping, but wanted to ask.

* iproute2: bash completion function for tc
From: Quentin Monnet @ 2016-04-26 7:28 UTC (permalink / raw)
To: Jamal Hadi Salim, Stephen Hemminger; +Cc: Vincent Jardin, netdev
Hi Jamal, Stephen,
I searched for a function providing auto-completion for `tc` utility in
bash, but I found none. So I have created one, and I would like share it
with the community. It is available here:
https://github.com/6WIND/tc_bash-completion/blob/master/tc
I would like to make it easily available to tc users, so here is a
twofold request:
* I do not know where to submit the code. Should I submit here on netdev
for inclusion in iproute2 package, or rather to the bash-completion
repository on GitHub? I feel like it would receive better feedback and
updates if pushed to iproute2. Could you please provide some advice here?
* The completion for `tc` seems to work well; I have tested it with many
commands, but I am no tc expert, and there are probably some cases where
the completion fails to propose the correct choices. I would be really
interested in any feedback/bug reports that you, or anyone on this list
who uses tc, could provide.
Best regards,
Quentin

Probably not, this is because:

otherwise flush won't work
- llist can only add a node to the head of list.

The ioremap() hidden behind the io_mapping_map_wc() convenience helper
can be used for remapping multiple pages. Extend the helper so that
future callers can use it for larger ranges.

OK.
So what are the plans in the future?
Keep a "generic" codel.h (compatibility reasons?) for net or is it your split?
AFAICS I have seen a codel-implementation in block.git#wb-buf-throttle.
Does it make sense to have a more "super-generic" codel.h for re-use
(not only for net and block)?
Just a thought.
