Rename rl_setmulti() to rl_rxfilter() as rl_rxfilter() will handle
IFF_ALLMULTI/IFF_PROMISC as well as multicast filter configuration.
Rewrite RX filter logic to reduce number of register accesses and
make it handle promiscuous/allmulti toggling without controller
reinitialization.
Previously rl(4) counted on controller reinitialization to reprogram
promiscuous configuration but r211767 resulted in avoiding
controller reinitialization whenever promiscuous mode is toggled.
To address this, keep track of driver's view of interface state and
handle IFF_ALLMULTI/IFF_PROMISC changes without reinitializing
controller. This should fix a regression introduced in r211267.
While I'm here remove unnecessary variable reassignment in ioctl
handler.
there must be only one SYSINIT with SI_SUB_RUN_SCHEDULER+SI_ORDER_ANY order
SI_SUB_RUN_SCHEDULER+SI_ORDER_ANY should only be used to call
scheduler() function which turns the initial thread into swapper proper
and thus there is no further SYSINIT processing.
Other SYSINITs with SI_SUB_RUN_SCHEDULER+SI_ORDER_ANY may get ordered
after scheduler() and thus never executed. That particular relative
order is semi-arbitrary.
Thus, change such places to use SI_ORDER_MIDDLE.
Also, use SI_ORDER_MIDDLE instead of correct, but less appealing,
SI_ORDER_ANY - 1.

If an RCS file is truncated, rcsfile_getdelta() will return NULL. Instead
of faulting, check for NULL. However, returning an error would cause csup

will cause csup to download the entire file as a fixup.
Implement hardware MAC statistics for BCM5705 or newer Broadcom
controllers. bge(4) exported MAC statistics on controllers that
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.
Apply the same workaround for clang to amd64's version of ldexp.c (as in
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().
After r207391, brgphy(4) passes resolved flow-control settings to
parent driver. Use that information to configure flow-control.
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.

/etc/rc.d/defaultroute currently bails immediately if all interfaces
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.
Set the number of RX frames to receive after RX MBUF low watermark

RX frames should not be a problem.
