Thanks for your reply.  I should have written more details about the
problem...

On recent 8-current, my de(4) NICs cannot send any (almost all) data
from it.

 * The system boots normally.

 * Probing/attaching the de(4) NICs are done successfully.

 * The system can receive data from the other hosts.  For example the
   following command was finished normally in 14 seconds:

$ /usr/bin/time scp other_host:/boot/kernel/kernel .
Password:
kernel                                        100% 4717KB 471.7KB/s   00:10
       14.03 real         0.53 user         0.40 sys
$ 

 * The system cannot send any data to the other hosts.  For example
   the following command was "stalled" and never finished
   (I interrupted the command after 5 minutes).  None of the data were
   sent:

$ /usr/bin/time scp /boot/kernel/kernel other_host:
Password:
kernel                                          1%  192KB   0.0KB/s - stalled -^CKilled by signal 2.
      336.01 real         0.05 user         0.17 sys
$

 * The system doesn't show any error/warning messages.

 * I can "slogin" from the other hosts to the system, and some small
   amount of text output (ex. an output of "dmesg") are done
   successfully.  But a bit large amount of text output are stopped
   after a few seconds.  For example:

$ ls -l /boot/kernel/kernel
-r-xr-xr-x  1 root  wheel  10975839 Dec 11 13:46 /boot/kernel/kernel
