* Fixed bugs in multicast address handling (flag was set in wrong register,David Greenman1995-05-261-266/+427
| | | | | | | | | | | | | | etc.). The tulip_start routine was rewritten to use less stack space (I've been having problems with wcarchive overflowing the stack and this should help a little). This version also has preliminary NetBSD support. Rod Grimes helped in testing this version of the driver. Thanks Rod. It's additionally been extensively tested here and on wcarchive.

The multicast hash algorithm uses the wrong (low) bits instead of the right (high) bits.

* Fixes to the aic7xxx sequencer code and device driver from Justin Gibbs:David Greenman1995-05-171-11/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) If a target initiated a sync negotiation with us and happened to chose a value above 15, the old code inadvertantly truncated it with an "& 0x0f". If the periferal picked something really bad like 0x32, you'd end up with an offset of 2 which would hang the drive since it didn't expect to ever get something so low. We now do a MIN(maxoffset, given_offset). 2) In the case of Wide cards, we were turning on sync transfers after a sucessfull wide negotiation. Now we leave the offset alone in the per target scratch space (which implies asyncronous transfers since we initialize it that way) until a syncronous negotation occurs. 3) We were advertizing a max offset of 15 instead of 8 for wide devices. 4) If the upper level SCSI code sent down a "SCSI_RESET", it would hang the system because we would end up sending a null command to the sequencer. Now we handle SCSI_RESET correctly by having the sequencer interrupt us when it is about to fill the message buffer so that we can fill it in ourselves. The sequencer will also "simulate" a command complete for these "message only" SCBs so that the kernel driver can finish up properly. The cdplay utility will send a "SCSI_REST" to the cdplayer if you use the reset command. 5) The code that handles SCSIINTs was broken in that if more than one type of error was true at once, we'd do outbs without the card being paused. The else clause after the busfree case was also an accident waiting to happen. I've now turned this into an if, else if, else type of thing, since in most cases when we handle one type of error, it should be okay to ignore the rest (ie if we have a SELTO, who cares if there was a parity error on the transaction?), but the section should really be rewritten after 2.0.5. This fix was the least obtrusive way to patch the problem. 6) Only tag either SDTR or WDTR negotiation on an SCB. The real problem is that I don't account for the case when an SCB that is tagged to do a particular type of negotiation completes or SELTOs (selection timeout) without the negotiation taking place, so the accounting of sdtrpending and wdtrpending gets screwed up. In the wide case, if we tag it to do both wdtr and sdtr, it only performs wdtr (since wdtr must occur first and we spread out the negotiation over two commands) so we always have sdtrpending set for that target and we never do a real SDTR. I fill properly fix the accounting after 2.0.5 goes out the door, but this works (as confirmed by Dan) on wide targets. Other stuff that is also included: 1) Don't do a bzero when recycling SCBs. The only thing that must explicitly be set to zero is the scb control byte which is done in ahc_get_scb. We also need to set the SG_list_pointer and SG_list_count to 0 for commands that do not transfer data. 2) Mask the interrupt type printout for the aic7870 case. The bit we were using to determine interrupt type is only valid for the aic7770. Submitted by: Justin Gibbs Notes: svn path=/head/; revision=8567

* After carefully reading three reference documents, and analyzingDavid Greenman1995-05-141-4/+4
| | | | | | | | | | | | | | | | | | the 802.3 frames generated by the DC21040 (which does automatic padding of less-than-minimum frames) and the frames generated by the 'ed' driver, I've found that there is indeed a bug in the size of "ETHER_MIN_LEN" as reported by several people, John Hay being the most recent. The driver was actually setting the length to 6+6+2+50 (64 bytes), which when adding in the CRC (which is automatically appended to the frame and not included in the length), the minimum frame is 4 bytes larger than it is supposed to be. All of this is confirmed by tcpdump showing 50 bytes of data for minimum frames from the 'ed' cards and 46 bytes from 'de' cards. This analysis has also revealed that there is garbage in the un-filled in portion at the end of the minimum frames from the 'ed' driver; I don't plan to fix this.
