Documentation/networking/ is full of cryptically named files with
driver documentation. This makes finding interesting information
at a glance really hard. Move all those files into a directory
called device_drivers (since not all drivers are for device) and
fix up references.

With all callbacks converted, and the timer callback prototype
switched over, the TIMER_FUNC_TYPE cast is no longer needed,
so remove it. Conversion was done with the following scripts:
perl -pi -e 's|\(TIMER_FUNC_TYPE\)||g' \
$(git grep TIMER_FUNC_TYPE | cut -d: -f1 | sort -u)
perl -pi -e 's|\(TIMER_DATA_TYPE\)||g' \
$(git grep TIMER_DATA_TYPE | cut -d: -f1 | sort -u)
The now unused macros are also dropped from include/linux/timer.h.

While build testing with randconfig on x86, I ran into this warning
that appears to have been around forever
drivers/net/ethernet/ti/tlan.c: In function ‘tlan_probe1’:
drivers/net/ethernet/ti/tlan.c:614:1: error: label ‘err_out’ defined but not used [-Werror=unused-label]

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.

When using internal 10 Mbps PHY, isolate the external PHY from MII bus.
