o Move setting the resource offsets to just after acquiring the ports in

code.
o Rename ed_pccard_Linksys to ed_pccard_dl100xx to reflect the underlying
chipset.
o Pass the ed_product structure into ed_pccard_{dl100xx,ax88x90} and have
those routines test the flags to see if this card should be probed in that
way.
o transition from ed_probe_Novell to ed_probe_Novell_generic since we already
have the resources setup.
o Move use of ed_probe_Novell_generic into ed_pccard_dl100xx to be more
consistant with ax88x90 case.
o simplify the code where we probe for the chipsets

as yet unknown, those cards report their MAC address a byte at a time.
However, other AX88x90 cards report the MAC address a word at a time.
Add a heuristic which looks at the high order bytes of the first 6
words. If they are all '0', assume the card is behaving like the
Linksys EC2T card. Since the default prefix for these cards appears
to be 00:e0:98, this appears to be a safe heuristic. While some cards
have been observed with different prefixes, they all work with this
heuristic.
I'm unsure if this is a bug in the EC2T card, or if it is a bug in the
initialization of the card. No other OS has this heuristic (although
w/o it, the MAC address that is used works).
listed in different orders. Since it is easy to identify the Modem

rather than hard coded rids. For such parts, go ahead and guess which
rid we should use based on the size. This guess appears reliable for
the two example cards that I have with different CIS info.

and linting procedure:
1. Remove useless sub-expression:
- if (*start || (!ifsspc && start > string && (nulonly || 1))) {
+ if (*start || (!ifsspc && start > string)) {
The sub-expression "(nulonly || 1)" always evaluates to true and
according to CVS logs seems to be just a left-over from some
debugging and introduced by accident. Removing the sub-expression
doesn't change semantics and a code inspection showed that the
variable "nulonly" is also not necessary here in any way (and the
expression would require fixing instead of removing).
2. Remove dead code:
- if (backslash && c == '\\') {
- if (read(STDIN_FILENO, &c, 1) != 1) {
- status = 1;
- break;
- }
- STPUTC(c, p);
- } else if (ap[1] != NULL && strchr(ifs, c) != NULL) {
+ if (ap[1] != NULL && strchr(ifs, c) != NULL) {
Inspection of the control and data flow showed that variable
"backslash" is always false (0) when the "if"-expression is
evaluated, hence the whole block is effectively dead code.
Additionally, the skipping of characters after a backslash is already
performed correctly a few lines above, so this code is also not
needed at all. According to the CVS logs and the ASH 0.2 sources,
this code existed in this way already since its early days.
3. Cleanup Style:
- ! trap[signo][0] == '\0' &&
+ ! (trap[signo][0] == '\0') &&
The expression wants to ensure the trap is not assigned the empty
string. But the "!" operator has higher precedence than "==", so the
comparison should be put into parenthesis to form the intended way of
expression. Nevertheless the code was effectively not really broken
as both particular NUL comparisons are semantically equal, of course.
But the parenthesized version is a lot more intuitive.
4. Remove shadowing variable declaration:
- char *q;
The declaration of symbol "q" hides another identical declaration of
"q" in the same context. As the other "q" is already reused multiple
times and also can be reused again without negative side-effects,
just remove the shadowing declaration.
5. Just small cosmetics:
- if (ifsset() != 0)
+ if (ifsset())
The ifsset() macro is already coded by returning the boolean result
of a comparison operator, so no need to compare this boolean result
again against a numerical value. This also aligns the macros usage to
the remaining existing code.

does not clear m_nextpkt for us. The mbufs are sent into netgraph and
then, if they contain a TCP packet delivered locally, they will enter
socket code again. They can pass the first assert in sbappendstream()
because m_nextpkt may be set not in the first mbuf, but deeper in the
chain. So the problem will trigger much later, when local program
reads the data from socket, and an mbuf with m_nextpkt becomes a
first one.
This bug was demasked by revision 1.54, when I made upcall queueable.
Before revision 1.54 there was a very small probability to have 2
mbufs in GRE socket buffer, because ng_ksocket_incoming2() dequeued
the first one immediately.
- in ng_ksocket_incoming2() clear m_nextpkt on all mbufs
read from socket.
- restore rev. 1.54 change in ng_ksocket_incoming().

refresh the PID which has the descriptor open. The PID is refreshed in various
operations like ioctl(2), kevent(2) or poll(2). This produces more accurate
information about current bpf consumers. While we are here remove the bd_pcomm
member of the bpf stats structure because now that we have an accurate PID we
can lookup the via the kern.proc.pid sysctl variable. This is the trick that
NetBSD decided to use to deal with this issue.
Special care needs to be taken when MFC'ing this change, as we have made a
change to the bpf stats structure. What will end up happening is we will leave
the pcomm structure but just mark it as being un-used. This way we keep the ABI
in tact.

an UP kernel this didn't cause problems, because the new mapping
would preempt the old one. In an SMP kernel this could lead to the
use of stale translations when processes move between CPUs at the
"right" moment. This fixes the last of the obvious SMP problems
and it should be safe to enable SMP by default now.
