the opportunity to handle an ioctl before generic ifioctl handling
occurs. This will ease extending the kernel and sharing of code
between drivers.
First steps: Make the signature of ifioctl_common() match struct
ifinet->if_ioctl. Convert SIOCSIFCAP and SIOCSIFMTU to the new
ifioctl() regime, throughout the kernel.
interrupts/sec -- not the other way around. Caught by yamt.
When I can confirm that it won't lock the chip up on the models claimed
to be problematic, I'll probably adjust the packet timers a bit further
to see if I can get latency down under low load. But this should be
better.
handling, ether_mediastatus() and ether_mediachange(). Check for
a non-ENXIO error return from mii_mediachg(). (ENXIO indicates
that a PHY is suspended.)
This patch shrinks the source code size by 979 lines. There was
a 5100-byte savings on the NetBSD/i386 kernel configuration, ALL.
I have made a few miscellaneous changes, too:
gem(4): use LIST_EMPTY(), LIST_FOREACH().
mtd(4): handle media ioctls, for a change!
axe(4): do not track link status in sc->axe_link any longer
nfe(4), aue(4), axe(4), udav(4), url(4): do not reset all PHYs
on a change of media
Except for the change to mtd(4), no functional changes are intended.

82571 manual and Intel Application Note 450. Previously, we were setting
RADV and TIDV/TADV values that didn't make any sense given the enormous
ITR value we were setting (well outside the range recommended by Intel
and quite possibly rejected silently by the chip as junk) and setting
RADV without setting RDTR, which is explicitly documented as having no
effect.
A considerable performance improvement is achieved for TCP and UDP at
gigabit speed. I need to revisit this to deal with the timer ticks
being 4X as long when the chip's in 100mbit mode, and to set values
for the older chips' interrupt timers that are more like what the
appnote recommends. This should help for 82543 and newer, though.
identify sockaddr_dl abuse that remains in the kernel, especially
the potential for overwriting memory past the end of a sockaddr_dl
with, e.g., memcpy(LLADDR(), ...).
