6323132f45 Remove manual vlan header insertion in em_encap(). It is unnecessary as the
generic vlan_start() takes care of it when vlan hardware insertion is disabled.

In em_set_promisc() add a note that BPF may also be enabled without going into
promisc mode.

d066071e5e Handle all error cases from bus_dmamap_load_mbuf_sg(). Those are:
- EFBIG means the mbuf chain was too long and bus_dma ran out of segments.
   Defragment the mbuf chain and try again. (Already existed, not changed.)
 - ENOMEM means bus_dma could not obtain enough bounce buffers at this point
   in time.  Defer sending and try again later.
 - All other errors, in particular EINVAL, are fatal and prevent the mbuf
   chain from ever going through.  Drop it and report error.
 - Checking (nsegs == 0) is unnecessary as bus_dmamap_load_mbuf_sg() always
   reports an error if it is < 1.

This prevents broken packets from clogging the interface queue indefinately.

f7318c4798 Rather than autoscaling the number of TIME_WAIT sockets to maxsockets / 5,
scale it to min(ephemeral port range / 2, maxsockets / 5) so that people
with large gobs of memory and/or large maxsockets settings will not
exhaust their entire ephemeral port range with sockets in the TIME_WAIT
state during periods of heavy load.

Those who wish to tweak the size of the TIME_WAIT zone can still do so with
net.inet.tcp.maxtcptw.

ba03f04b14 Tweak the code to handle intercepting BIOS calls to int 0x15 to shave
another 16 bytes off of BTX (and thus boot2):
- Compare against the value of %eax that is saved on the stack instead of
  loading it into %eax (which requires saving the current %eax on the
  stack).
- Use %ch to examine the keyboard flag state in the BIOS to see if
  Ctrl-Alt-Del is pressed instead of %al so we don't have to save %eax on
  the stack anymore.

79660d10e4 Optimize the int 15/87 handler for space to shave another 16 bytes off of
BTX (and thus boot2):
- Don't bother saving %eax, %ebx, or %ecx as it is not necessary.
- Use a more compact sequence to load the base value out of a GDT entry
  by loading the contiguous low 24 bits into the upper 24 bits of %eax,
  loading the high 8 bits into %al, and using a ror to rotate the bits
  (2 mov's and a ror) rather than loading the pieces in smaller chunks
  (3 mov's and a shl).
- Use movzwl + leal instead of movl + movw + shll + addl.
- Use 'xchgl %eax,%foo' rather than 'movl %eax,%foo' for cases where
  it's ok to trash %eax.  xchgl %eax, foo is a 1-byte opcode whereas the
  mov is a 2-byte opcode.
- Use movzwl rather than xorl + movw.

5eae8ee0ac When tcp_output() receives an error upon sending a packet it reverts parts
of its internal state to ignore the failed send and try again a bit later.
If the error is EPERM the packet got blocked by the local firewall and the
revert may cause the session to get stuck and retry indefinitely.  This way
we treat it like a packet loss and let the retransmit timer and timeouts
do their work over time.

The correct behavior is to drop a connection that gets an EPERM error.
However this _may_ introduce some POLA problems and a two commit approach
was chosen.

b09219dff2 Various fixups, especially for the upcomming High Definition Audio
commit.

1) sys/dev/sound/pcm/sound.h
   sys/dev/sound/pcm/channel.c
   * Be more specific: SD_F_SOFTVOL -> SD_F_SOFTPCMVOL
2) sys/dev/sound/pcm/mixer.[ch]
   * Implement
       mix_setparentchild()
       mix_setrealdev()
       mix_getparent()
       mix_getchild()
     The purpose of these functions is implement relative volume
     adjustment, such as to tie two or more mixer device into a
     single logical device. Usefull for the upcoming HDA driver
     and few AC97 codec (such as AD1981B) where the master volume
     "vol" need to be implemented using this logical manner.
3) sys/dev/sound/pcm/ac97_patch.[ch]
   * Patch for AD1981B codec to enable (automuting) headphone jack sense.
4) sys/dev/sound/pcm/ac97.c
   * Implement proper logical master volume for AD9181B codec
     through various mix_set{parentchild,realdev}(). Tie both
     "ogain" (headphone volume) and "phone" (speaker/lineout) to
     a logical "vol".
5) sys/dev/sound/pcm/usb/uaudio_pcm.c
   * ditto, for "vol" -> { "pcm" }.

03e16bd83a Fix the IPv4 multicast routing detach path. On interface detach whilst
the MROUTER is running, the system would panic as described in the PR.

The fix in the PR is a good start, however, the other state associated
with the multicast forwarding cache has to be freed in order to avoid
leaking memory and other possible panics.

More care and attention is needed in this area.

b8c88cc531 The IPv4 code should clean up multicast group state when an interface
goes away. Without this change, it leaks in_multi (and often ether_multi
state) if many clonable interfaces are created and destroyed in quick
succession.

The concept of this fix is borrowed from KAME. Detailed information about
this behaviour, as well as test cases, are available in the PR.
