o) Make the Simple Executive's warning function print "WARNING: " on the same
line as the warning it is displaying, rather than on a separate line.
reducing the number of runtime checks done by the SDK code.
o) Group board/CPU information at early startup by subject matter, so that e.g.
CPU information is adjacent to CPU information and board information is
adjacent to board information.

port connected to the Broadcom switch does not seem operable, but it's unclear
if that's simply due to a lack of configuration information for the switch.
The switch does not seem to present any identifying information via MDIO,
and is a BCM56512.
address passed from the bootloader, rather than using a hard-coded value.
Make FreeBSD announce itself on the LED display similar to other kernels.
Remove uses of the previous LED routines, which were under-used and only used
in drivers for what seem like debugging purposes, despite those drivers being
widely-tested.
Remove several inlines for accessing memory that duplicate other functions
which are now used instead, as they are now entirely unused.
- All packets in NETISR_IP queue are in net byte order.
- ip_input() is entered in net byte order and converts packet
to host byte order right _after_ processing pfil(9) hooks.
- ip_output() is entered in host byte order and converts packet
to net byte order right _before_ processing pfil(9) hooks.
- ip_fragment() accepts and emits packet in net byte order.
- ip_forward(), ip_mloopback() use host byte order (untouched actually).
- ip_fastforward() no longer modifies packet at all (except ip_ttl).
- Swapping of byte order there and back removed from the following modules:
pf(4), ipfw(4), enc(4), if_bridge(4).
- Swapping of byte order added to ipfilter(4), based on __FreeBSD_version
- __FreeBSD_version bumped.
- pfil(9) manual page updated.

altq_add() and its descendants. Currently altq(4) in FreeBSD is configured
via pf(4) ioctls, which can't configure altq(4) w/o holding locks.
Fortunately, altq(4) code in spife of using M_WAITOK is ready to receive
NULL from malloc(9), so change is mostly mechanical. While here, utilize
M_ZERO instead of bzero().
A large redesign needed to achieve M_WAITOK usage when configuring altq(4).
Or an alternative (not pf(4)) configuration interface should be implemented.

reside, and move there ipfw(4) and pf(4).
o Move most modified parts of pf out of contrib.
Actual movements:
sys/contrib/pf/net/*.c -> sys/netpfil/pf/
sys/contrib/pf/net/*.h -> sys/net/
contrib/pf/pfctl/*.c -> sbin/pfctl
contrib/pf/pfctl/*.h -> sbin/pfctl
contrib/pf/pfctl/pfctl.8 -> sbin/pfctl
contrib/pf/pfctl/*.4 -> share/man/man4
contrib/pf/pfctl/*.5 -> share/man/man5
sys/netinet/ipfw -> sys/netpfil/ipfw
The arguable movement is pf/net/*.h -> sys/net. There are
future plans to refactor pf includes, so I decided not to
break things twice.
Not modified bits of pf left in contrib: authpf, ftp-proxy,
tftp-proxy, pflogd.
The ipfw(4) movement is planned to be merged to stable/9,
to make head and stable match.

including the include directive.
Fix minor build issue corrected by converting yypush_buffer_state and
yypop_buffer_state to yy_set_buffer_state and a hard-coded 100-deep
stack. It was easier to fix it here than to import that support into
our flex.
The new tools and test hardness remain unsupported at the moment.
- Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs.
These are available as t3_tom and t4_tom modules that augment cxgb(4)
and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as
usual with or without these extra features.
- iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the
works and will follow soon.
Build-tested with make universe.
30s overview
============
What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the
capabilities of an interface:
# ifconfig -m | grep TOE
Enable/disable TCP offload on an interface (just like any other ifnet
capability):
# ifconfig cxgbe0 toe
# ifconfig cxgbe0 -toe
Which connections are offloaded? Look for toe4 and/or toe6 in the
output of netstat and sockstat:
# netstat -np tcp | grep toe
# sockstat -46c | grep toe
