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.

v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86

This chunk seems to be breaking MTUs > 1500 for me.

Please correct me if I'm wrong but it seems like we are now limiting
_all_ ethernet drivers to ETH_DATA_LEN in net-next.

No, because the driver can increase the netdev->max_mtu value as needed.

But since almost no driver is doing that, yet, right now in net-next
jumbo frames are not possible, no?  I thought the idea was the leave
the value at 0 so drivers can opt-in as needed but since setup_ether()
is initializing to 1500 now all ethernet driver get a default of
limiting to 1500.

IOW this patch made checks which were done only in eth_change_mtu()
mandatory for all drivers.

all ethernet drivers to be clear

The conversions he made were in cases where the driver's method was doing
exactly the same thing eth_change_mtu() does not.

He strictly worked to keep the behavior identical compared to before his
changes, please read his patches carefully.

Hm.  I must be missing something really obvious.  I just booted
net-next an hour ago and couldn't set MTU to anything larger than 1500
on either nfp or igb.  As far as I can read the code it will set the
max_mtu to 1500 in setup_ether() but none of the jumbo-capable drivers
had been touched by Jarod so far...

Indeed.

Jarod, this doesn't work.

I guess the idea was that if the driver overrides ndo_change_mtu and
enforeced it's limits there, the driver would still work after your
changes.

But that isn't what is happening, look at the IGB example.

It uses ether_setup(), which sets those new defaults, but now when
the MTU is changed you enforce those default min/max before the
driver's ->ndo_change_mtu() has a change to step in front and make
the decision on it's own.

This means your changes pretty much did indeed break a lot of
drivers's ability to set larger than a 1500 byte MTU.

Argh. Yeah, I see it now. I was primarily operating with the follow-on
patches also in play, which do touch all the ethernet drivers and set
max_mtu to match current behavior, didn't consider the max_mtu case where
only the initial patches were applied and the follow-on ones weren't. I've
sent that set, which should theoretically make this problem go away, but I
can also try to rework things if need be to restore intermediate jumbo
frames functionality. (And there are actually non-ethernet devices that
also call ether_setup and may or may not have larger than 1500 mtu that
aren't yet addressed by that follow-on set).

Looks like the simplest thing to do is going to be to revert a52ad514, and
only make that change after all callers of ether_setup() are setting
min/max_mtu themselves as needed, then it can be reintroduced.
