8423e00b36 Eventhough r203504 eliminates taste traffic provoked by vdev_geom.c,
ZFS still like to open all vdevs, close them and open them again,
which in turn provokes taste traffic anyway.

I don't know of any clean way to fix it, so do it the hard way - if we can't
open provider for writing just retry 5 times with 0.5 pauses. This should
elimitate accidental races caused by other classes tasting providers created on
top of our vdevs.

98332c8c71 Right now, WITNESS just blindly pipes all the output to the
(TOCONS | TOLOG) mask even when called from DDB points.
That breaks several output, where the most notable is textdump output.
Fix this by having configurable callbacks passed to witness_list_locks()
and witness_display_spinlock() for printing out datas.

88a7eb29d2 This fixes a bug with the one-2-one model socket when a
user sets up a socket to a server sends data and closes
the socket before the server has called accept(). It used
to NOT work at all. Now we add a flag to the assoc and
defer assoc cleanup so that the accept will suceed.

8775710a1d SiS190 supports RX 10 bytes padding, CRC stripping as well as VLAN
hardware tag insertion/stripping. Remove conditional code that
disables these hardware features on SiS190. Also nuke RX fixup code
which is no more required on strict-alignment architectures because
SiS190 supports RX 10 bytes padding.
Now all hardware features except jumbo frame and WOL are supported.
Thanks to Masa Murayama who confirmed SiS190 also has the same
hardware features of SiS191.
I guess the only difference between SiS191 and SiS190 would be
jumbo frame support. It will be implemented in near future.

65329b3111 Implement TSO and TSO over VLAN. Increase number of allowed
fragmentation of mbuf chain to 32 from 16 because TSO can send 64KB
sized packet which in turn requires long list of mbuf chain. Due to
lack of documentation, I'm not sure whether driver have to pull up
ethernet/IP/TCP header with options to make controller work but
driver have to parse TCP header to update pseudo TCP checksum
anyway. The controller expects pseudo TCP checksum computed by
upper stack and the checksum should follow the MS NDIS
specification to make TSO work.

8da9c50775 Export hardware MAC statistics through sysctl node. Previously
fxp(4) already used to extract most hardware MAC statistics but it
didn't show them. With this change, all MAC statistics counters
are exported. Because there are a couple of new counters for 82558
and 82559, enable extended MAC statistics functionality to get
these counters. Accoring to public data sheet, 82559 MAC statistics
return 24 DWORD counters(3 counters are unknown at this moment) so
increase MAC counter structure to meet the MAC statistics block size.
The completion of MAC counter dump is now checked against
FXP_STATS_DR_COMPLETE status code which is appended at the end of
status block. Previously fxp(4) ignored the status of the
FXP_SCB_COMMAND_CU_DUMPRESET command. fxp(4) does not wait for the
completion of pending command before issuing
FXP_SCB_COMMAND_CU_DUMPRESET. Instead it skips the command and try
it next time. This scheme may show better performance but there is
chance to loose updated counters after stopping controller. So make
sure to update MAC statistics in fxp_stop().
While I'm here move sysctl node creation to fxp_sysctl_node().

eee9d99231 Push down the acquisition of the page queues lock into vm_pageq_remove().
(This eliminates a surprising number of page queues lock acquisitions by
vm_fault() because the page's queue is PQ_NONE and thus the page queues
lock is not needed to remove the page from a queue.)

db1f085eee Call vm_page_deactivate() rather than vm_page_dontneed() in
swp_pager_force_pagein().  By dirtying the page, swp_pager_force_pagein()
forces vm_page_dontneed() to insert the page at the head of the inactive
queue, just like vm_page_deactivate() does.  Moreover, because the page
was invalid, it can't have been mapped, and thus the other effect of
vm_page_dontneed(), clearing the page's reference bits has no effect.  In
summary, there is no reason to call vm_page_dontneed() since its effect
will be identical to calling the simpler vm_page_deactivate().

7251782989 8255x configure command requires number of bytes of configuration
table. The default size of the configuration table was 22 bytes. To
use extended feature of 82550/82551 the configuration table size
was expanded to 32 bytes. The added configuration for 82550/82551
specifies VLAN hardware tagging and IPSec configuration as well as
TCO.
To make configuration easier fxp(4) used a configuration template
and the template was copied to configuration table. After that,
some parameters of the configuration table was changed depending on
controller type and operation mode. However the size of template
was 22 bytes so some configuration parameters were not properly
initialized on 82550/82551.
Fix this by increasing the template size. For 82557, 82558 and
82559 the size of the configuration is still 22 bytes.

that host didn't join in promiscuous mode, driver have to set
promiscuous mode for multicast frames as well.
