Virgin import of Xircom PCCARD driver v1.20 (1999/06/13):

1999-06-22T19:12:08+00:00

* Conformance with Dingo specification. This includes:
	Collision/error statistics gathering.
	Multicast address filtering, eg. the hash filter.
	Initialisation and interrupt handling sequences.
Note that I've started on some of this already in v1.20.

* The probe routine needs some more work, to identify oddities such as the
  REM10.

* There are still problems with the autonegotiation code; specifically, it
  won't autonegotiate with some 10/100 hubs.  This might simply be the hardware
  not getting along, in which case there's nothing we can do, but it's still
  worth investigating

* CEM28/CEM33 support.  Should be able to integrate this directly from the
  Linux code.

* Performance enhancements:
	Full-duplex on 10Mbit networks.
	Virtual shared-memory mode.
	Early send and receive modes.

Virgin import of Xircom PCCARD driver v1.19.

1999-05-14T02:26:20+00:00

v1.19 (1999/04/15) updates the CEM56/REM56 support.

Current bugs & misfeatures
--------------------------
* CE2 cards still not working reliably. Unclear if this is related to
  packet I/O code or interrupt handling.
* Autonegotiation support remains flaky. We're now OK with 10Mbit auto
  hubs, but certain combination of hardware will fail to connect.

Virgin import of Xircom PCCARD driver v1.18

1999-05-14T02:00:38+00:00

Virgin import of Xircom PCCARD driver v1.17

1999-05-14T01:58:59+00:00

v1.17 (1999/03/28) has xperimental fixes to 10Mbit autonegotiation and
CE2 input lockup.

KNOWN BUGS
==========

* Media auto-negotiation is definitely not right.  It will work in most
  circumstances and seems to connect OK to most 100Mbit networks, however some
  pathological combinations of hubs/networks/peers seem to confuse it.

* CE2 support is somewhat flakey (ranging from 'works perfectly' to 'hangs the
  machine' so far).  I've fixed the probe routine and a potential lockup in
  the output routine, but a lot of people still report that they can't receive
  or transmit.

* You won't be able to use the modem and Ethenet parts of a multifunction card
  simultaneously.  This is limitation the current FreeBSD PCMCIA support.
  Likewise, there is no support for CardBus devices.

Virgin import of Xircom PCCARD driver v1.14

1999-05-14T01:50:10+00:00

This driver is mostly based on the `xirc2ps' driver for Linux by Werner
Koch.  Werner has even allowed his code to be distributed under a BSD licence,
making our life considerably easier -- thanks Werner!

This driver supports:
* Intel EtherExpress(TM) PRO/100 PCCARD (16-bit version)
* Xircom CreditCard CE2 / CEM28 / CEM33 / CE3 / CEM56 Ethernet adapters.
* Toshiba Advanced Network 10/100 PCCARD
* Certain Compaq Netelligent 10/100 branded cards

v1.14 has major changes to media selection code, and bugfixes in the
probe routine.
