thorpej 569e9a31e2 For SLIP/STRIP/PPP, use generic soft interrupts, if available. 2001-01-15 16:33:30 +00:00
thorpej 1ce7cbc90b Sync with if_sl.c,v 1.65:
Once we have a complete frame, schedule a STRIP software interrupt,
and manipulate ipintrq from there.  This will allow us to clean up
the use of splimp() in this file later.

thorpej a5ee0c0a19 Sync with if_sl.c,v 1.64:
Make the buffer management in STRIP just a little less evil.

thorpej c5293456da Adapt to bpfattach() changes, and further centralize the bpfattach()
and bpfdetach() calls into link-type subroutines where possible.

thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

perry 41c3fea850 add multiple inclusion protection (and cleanup). 1998-02-09 17:43:44 +00:00
thorpej 7ec7599a61 Change the interface name from "st" to "strip", so as to match the
pseudo-device option listed in the kernel config file, and to avoid
a name clash with the "SCSI tape" driver.

thorpej d1c9089a16 Update for the new mbuf code, in a slighly kludgy way. Basically, these
drivers played a somewhat evil trick with clusters, which is now
replaced by a somewhat evil trick with regular malloc'd memory.

jonathan 36c640a447 * Remove old, unused SLIP variables from softc.
* Fix radio error-message parsing bug: old comparison against error
  prefix string  off by the size of the Starmode link-level protocol field.
* Fix radio reset finite state machine, given that parsing works properly.
* Add debugging messages about reset FSM if IFF_DEBUG is set.
* Remove #ifdefs notdef around back the check that discards newlines at
  the beginning of a frame. Every error message from the radio has a newline,
  as the radio send error messages terminated by \r\n, not  just \r like data
  frames. Not dropping the \n garbles the following data frame.
* Remove unused low-level debugging routines.
* Reformat the low-level bytestuff/RLL code to match the canonical source.
* Reduce MTU to 1100 bytes; 1200 bytes can overflow the radio buffers if the
  bytestuff/RLL does poorly.
* Fix radio-probe string to _not_ include a frame delimiter (\r): sending
  a \r to the radio tickles a bug in the firmware, causing the radio to
  smash the next frame sent after  the "**\r" probe string.
* Add calls to the tty t_oproc routine to make sure the probe and reset
  strings get sent to the modem promptly, rather than waiting for the next
  packet.
* Add PPP-style calls to the tty start-output function; seems to
  reduce latency marginally.

still to do:
* Flush output queue if resetting, since the radio is going to drop
  frames on the floor anyway if it needs resetting.
* Reduce tty start-output calls.

jonathan ed314bc45a Catch up to removal of if_unit and addition of if_xname and sc_unit,
blindly following the changes to if_sl.c.
