Different from the submitted patch, a string ending with '[=' does not cause

maintain the statistics in the NIC's internal memory. Newer
controllers require register access to fetch these values. These
counters provide useful information to diagnose driver issues.
The check for alignment should be made against the physical address and not
the virtual address that maps it.

r212976): order the incoming arguments to fscale as st(0), st(1), and
mark temp2 volatile (only in case of compilation with clang) to force
clang to pop it correctly. No binary change when compiled with gcc.
This fixes ldexp() when compiled with clang on amd64, which makes
drand48() and friends work correctly again, and this in turn fixes
perl's tempfile().

One drawback is there is no way to disable flow-control as we still
don't have proper way to not advertise RX/TX pause capability to
link partner. But I don't think it would cause severe problems and
users can selectively disable flow-control in switch port.

set to use DHCP have no carrier. This can cause grief as it may take
some time for link to be established, and defaultroute may terminate
before this happens.
Introduce a defaultroute_carrier_delay variable and then wait that long
in defaultroute before bailing if no interfaces have carrier. With the
default settings defaultroute will wait for five seconds for this, and
the original 30 second wait for a default route to appear is unchanged.
Note that there is in discussion an alternative approach to the broader
problem of waiting for DHCP-configured routes. However, this change
addresses a real problem in the current defaultroute script.

low watermark is greater than or equal to 4 so receiving two more

The previous version of code have no locking when testing rt_refcnt.
The result of the lack of locking may result in a condition where
a routing entry have a reference count but at the same time have
RTPRF_OURS bit set and an expiration timer. These would eventually
lead to a panic:
panic: rtqkill route really not free

the cdevp_list but a separate directory list is needed for user created

Add a new directory entry flag DE_USER to mark entries which should

A new function to traverse cdevp_list and the directory list will be
