Renamed varible dst in ray_rx to mp as it is a pointer to an mbuf.
Correctly grok addresses in data packets.
Promte a couple of RECERRs to real errors.
Rewrote intro at top of file to reflect my better understanding of how it
the memory mapping works.
Clear the DONE list and move some thoughts into the TODO list.
Remove RECERR from RAY_DEBUG
Start to use a desired network parameter structure, only used in download
code as I've realised that there are some problems with the idea.
Break up ray_rx, and move the data packet handler into a seperate function. This meant some knock on changes in ray_rx_mgt/ray_rx_ctl to do with
mbuf freeing.
Remove some debug code/XXX comments that are out of date.
Force alphas to prefer mem mapping as the default.
Basically, we have a pointer to a function which we can call which will
return us a pointer to firmware for the card we have. We call this function
(if it's non-NULL) with the address of our mdvec f/w pointer.
The way this works is that if ispfw (as a module or a static) is loaded,
it initializes the pointer in isp_pci, so we can call into to it to fetch
a pointer to a f/w set.
If ispfw is MOD_UNLOADed, it's retained a pointer to our mdvec f/w pointers,
which then get zeroed out so we don't have any references to data that's
now gone from kernel memory. Removing the f/w saves ~360KBytes.
Alas, there is no autounload mechanism that works for is here.
through, establish what our LUN width is. Unfortunately, we can't ask
the f/w. If we loaded the f/w, we'll now assume we have expanded LUNs
(SCCLUN for fibre channel, just plain 32 LUN for SCSI). If we didn't
load firmware, assume 8 LUNs for SCSI and 1 LUN for Fibre Channel. We
have to assume only one LUN for Fibre Channel because the LUN setting
in Request Queue entries is in different places whether we have SCCLUN
firmware or not, so the only LUN guaranteed to work for both is LUN 0.
Clean up the rest of isp.c so that ISP2100_SCCLUN defines aren't used-
instead use run time determinants based upon isp->isp_maxluns.
After starting firmware, delay 500us to give it a chance to get rolling.
Fix the interrupt service routine to check for both isr && sema being zero
before thinking this was a spurious interrupt. Following the manuals,
allow for both Mailbox as well as Queue Reponse type interrupts for regular
SCSI.
(we always support fabric now). Remove SCCLUN definition (we always
support SCCLUN now, if we load the f/w). Add typedef definition of an
external firmware fetch function.
need this RSN.
Remove a pointless warning in the root device locating code.
Remove the "wd" compatibility name from the "ad" driver.
WARNING: If you have not updated to use /dev/wd* in your /etc/fstab
and modern bootblocks, it would be a very good idea to do so BEFORE
you upgrade your kernel.
Implement the Solaris way to break into DDB over a serial console
instead of sending a break. Sending the character sequence
CR ~ ^b will break the kernel into DDB (if DDB is enabled).

layout introduced in driver 1.5.3. The driver was
confused by the bogus TEKRAM table used to translate
user sync. setting to SCSI sync. factor.
Btw, the new TEKRAM DC-390 U3D and U3W Ultra-160
controllers seem to be using BIOS from SYMBIOS/LSI
and thus SYMBIOS NVRAM layout.
If that means that TEKRAM will now offer real
SYMBIOS software compatible SCSI controllers, then
it is a *GREAT NEWS*.
What we'd like to know is whether or not we have a listener
upstream that really hasn't configured yet. If we do, then
we can give a more sensible reply here. If not, then we can
reject this out of hand.
Choices for what to send were
Not Ready, Unit Not Self-Configured Yet
(0x2,0x3e,0x00)
for the former and
Illegal Request, Logical Unit Not Supported
(0x5,0x25,0x00)
for the latter.
We used to decide whether there was at least one listener
based upon whether the black hole driver was configured.
However, recent config(8) changes have made this hard to do
at this time.
Actually, we didn't use the above quite yet, but were sure considering it.
Generated a new macor, RAY_RECERR for reporting errors with. Verbosity set with IFF_DEBUG (recommended at present).
Add PRIBIO to tsleeps.
Catch detach on ray_ccs_alloc a little better.
Move sc_promisc into desired and current n/w parameters.
Remove IFQ_PEEK, we know the driver runs okay without it.
Drain the output queue in ray_stop.
Only use ray_mcast for ADD/DEL multi ioctls. ray_init_multi resets the
multicast list on startup. Simplifies ray_init a little.
Tidy some old comments.
ray_download_done now copies the whole desired n/w parameter set into the
current set. This is because I was missing soem parameters - like the
net type!
