back to the original environ unconditionally. The setting of the
variable to save the previous environ is conditional; it happens when
ENV.e_committed is set. Therefore, don't try to swap the env back
unless the previous env has been initialized.

This chip works very unreliably on my Lanner embedded PC with the rl driver.
Lots of watchdog timeouts or poor performance.
Forcing the media type to 10 Meg (ifconfig rl0 media 10baseT/UTP) is a good
workaround.
This looks very similar to the problem reported in PR kern/18790
It is interesting to note that the linux driver has lots of special
case code for this chip.
More detail describing why chmod is installed into ${INSTALLTMP} since
rev 1.176:
We use Perl's MakeMaker-generated makefiles to install Perl. Since we
can't hack up MakeMaker's MM_Unix.pm to suit our build, we need chmod
to be around until we use our own makefiles to install perl.

This lets you resolve pathnames to their underlying physical path:
critter# realpath /sys/kern/subr_disk.c

Update the pwd man-page slightly.
* Some dummynet code incorrectly handled a malloc()-allocated pseudo-mbuf
header structure, called "pkt," and could consequently pollute the mbuf
free list if it was ever passed to m_freem(). The fix involved passing not
pkt, but essentially pkt->m_next (which is a real mbuf) to the mbuf
utility routines.
* Also, for dummynet, in bdg_forward(), made the code copy the ethernet header
back into the mbuf (prepended) because the dummynet code that follows expects
it to be there but it is, unfortunately for dummynet, passed to bdg_forward
as a seperate argument.

is already in 32-bit mode, we need to be able to detect this and still
read the chip ID code. Detecting 32-bit mode is actually a little
tricky, since we want to avoid turning it on accidentally. The easiest
way to do it is to just try and read the PCI subsystem ID from the
bus control registers using 16-bit accesses and compare that with the
value read from PCI config space. If they match, then we know we're in
16-bit mode, otherwise we assume 32-bit mode.
