d7097da403 Make TSO (TCP segmentation offload) capabilities visible and accessible with
'ifconfig em0 tso' and 'ifconfig em0 -tso'.  TSO for IPv4 and IPv6 is always
enabled or disabled together.  The driver may enable only one if it doesn't
support both.

Document 'tso' and '-tso' in the ifconfig(8) man pages.

233dcce118 First step of TSO (TCP segmentation offload) support in our network stack.
o add IFCAP_TSO[46] for drivers to announce this capability for IPv4 and IPv6
 o add CSUM_TSO flag to mbuf pkthdr csum_flags field
 o add tso_segsz field to mbuf pkthdr
 o enhance ip_output() packet length check to allow for large TSO packets
 o extend tcp_maxmtu[46]() with a flag pointer to pass interface capabilities
 o adjust all callers of tcp_maxmtu[46]() accordingly

ccf2597759 While convenient, avoid using alloca() for reasons specified in
the BUGS section of the alloca(3) manpage.  In particular, when
the number of TCP sockets is several tens of thousand, trying to
"sysctl -a" would SIGSEGV on the net.inet.tcp.pcblist entry (it
would exceed the stacksize ulimit, in an undetectable manner).

4962065404 Refine previous revision to allow acpi_wakecode.h to be safely built
from both the acpi module build directory and a kernel build directory.
The latter didn't work when one attempted to build a kernel which had
"device acpi" with the "make kernel-toolchain buildkernel" command
because a cross-compiler couldn't find anything in the standard system
include path (it's empty in the kernel-toolchain case).

Fix this by passing a better root path to kernel headers (src/sys)
which works for both cases, kernel and module (-I@ only worked for
module).

Also, while here, pass -nostdinc (and a different spelling for icc) --
it's a feature that the kernel source tree is self-contained, and this
change enforces this.

2c857a9be9 o Backout rev. 1.125 of in_pcb.c. It appeared to behave extremely
bad under high load. For example with 40k sockets and 25k tcptw
  entries, connect() syscall can run for seconds. Debugging showed
  that it iterates the cycle millions times and purges thousands of
  tcptw entries at a time.
  Besides practical unusability this change is architecturally
  wrong. First, in_pcblookup_local() is used in connect() and bind()
  syscalls. No stale entries purging shouldn't be done here. Second,
  it is a layering violation.
o Return back the tcptw purging cycle to tcp_timer_2msl_tw(),
  that was removed in rev. 1.78 by rwatson. The commit log of this
  revision tells nothing about the reason cycle was removed. Now
  we need this cycle, since major cleaner of stale tcptw structures
  is removed.
o Disable probably necessary, but now unused
  tcp_twrecycleable() function.

- only release device if g_gate_destroy() failed - if it succeeded device

- various other changes which makes forcible destruction reliable.

23da540855 The FreeBSD by default "disables" hyper-threading cores, by not scheduling
any threads to them. However, it still counts those cores as "active but
permanently idle" when calculating system-wide CPUs statistics. It is
incorrect, since it skews statistics quite a bit and creates real problems
for certain types of applications (monitoring applications for example),
by making them believe that the system does have enough idle CPU resources,
while in fact it does not.

Correct the problem by not calling performance counting routines on "disabled"
cores. The cleaner solution would be to just disable APIC timer interrupts on
those cores completely, but ENOTIME here and it is not clear if the
additional complexity really worth minor performance gain.

3c03c7095e GC dead code. If we want to stay polite to the foreign compilers,
we can find another way to issue an #error, but using a preprocessed
assembler for that purpose and clobbering libc.a with an empty .o
just for the sake of #error reporting is way too much of a burden.
