code only passed up the connection to the tcp stack when it was complete,
so it went directly into the so_comp (complete) queue. However, with
accept filters, there is an additional phase before calling it "complete".

renames the imen_mtx for x86 SMP, but also uses the lock to protect
access to the 8259 PIC on x86 UP. This also adds an appropriate lock to

Hopefully MFC: before the 4.5 release
for this file, but here goes nothing. This was my first attempt at
tidying up this file. Unfortunately, it just exposes many more horrors
in the code itself that had been masked by the eyesore that was there
before. I think this just needs to be put out of its misery.

re-cached, resulting in the leak. This commit is an interim fix until DES

to Phil Kernick:
"The problem is that in full duplex mode, the Conexant chip always reports a
carrier lost error, even when the frame is successfully sent. So, if we
have a Conexant chip, then ignore carrier lost when in full duplex
mode."
Since the Xircom chips seem to have the same issue and since we already
have a workaround for this, just expand the workaround test to also
check for DC_IS_CONEXANT().

This fixes the following bug:

All TCP ISNs that are sent out are valid cookies, which allows entries
in the syncache to be dropped and still have the ACK accepted later.
As all entries pass through the syncache, there is no sudden switchover
from cache -> cookies when the cache is full; instead, syncache entries
simply have a reduced lifetime. More details may be found in the
"Resisting DoS attacks with a SYN cache" paper in the Usenix BSDCon 2002
conference proceedings.
