- Add some additional config block bits for the i82558/i82559.
- Change the config block template to only fill in the must-be-one
reserved bits, leave fxp_init() to fill in all the important things.
- On the i82558/i82559, we can use "Receive Long Frames" rather than
"Save Bad Frames" to support the VLAN MTU.
- Use 802.3x flow control on the i82558/i82559. This is all handled
transparently by the hardware. When in promiscuous mode, allow
wire-watchers to see the flow control frames.
- Use the Extended TxCB format on the i82558/i82559. This places two
Transmit Buffer Descriptors directly in the TxCB, which should cover
the vast majority of packets transmitted. This saves PCI transactions
that would otherwise be required to fetch the TBD list.
With the tansmit queue length changes from yesterday, this gets us up to
11.5MB/s TCP transmit speed, out of an absolute maximum of 12MB/s possible
on a 100Mb/s link.
This fixes a `hang' on shutdown when the `Synchronise Cache' command
is sent to a disk. (It uses polled mode because it is called from inside
a shutdown hook).
interrupt priority, to avoid allocating additional mbufs on
splsched(). Move some other misc bits out of splched()-guarded
section. This should make the code a bit more friendly wrt e.g.
clock interrupts. Sligh performance improvement was observed with
this change (like 1-2% on slow machine), even.
This also fixes ancient kern/2478 by Bill Sommerfeld.
keeps us from stomping on ourselves.
Say we're in the middle of re-evaluating a loop (and sleeping) when a
command completes, or a timer refires, and this *other* thread decides
*it* wants to start re-evaluating the loop. Bad news.
We have to be a bit careful- if we can't acquire the MBOX semaphore at
interrupt level, we will simulate a host interface error. This is a bit
of a temp workaround. There's some work underway driven by a NetBSD
commercial user that will try and force most mailbox stuff into a
part A/part B interrupt driven model.
0xfe on my gateway 2000 circa 1993). That should not affect broken controllers
that choke on the kbc_auxtest, because for those the write/read test succeeds.
Although WEP is used in Windows also in an old firm,
because WEP is processed by the windows driver side.
If Prism2 Firm version is more than 0.8.3, WEP does work without 'Promiscuous ON'.
Roaming mode can change value into 'firm mode' and disable.
Authentication mode can change into 'Open System authentication'
and 'Shared Key Authentication' with Prism2 chip.
wi_get_id() was introduced in order that chip might judge automatically
whether it is Prism2 chip. Therefore, a pp_prism2 entry in
"struct wi_pcmcia_product" became unnecessary.
done when the command-in-progress bit has been cleared. The 1ms
time that is mentioned also seems wrong; 20,000us is not enough
on at least one machine. So, do a delay(100000) in ex_reset.
Fortunately, this function is only called when the card is
attached or when hardware failure is suspected.
While here, only mask one 1 bit in the 'reset hack' case.
