thorpej dc5a586c1c Use the common MII bit-bang module. 1999-11-19 18:17:14 +00:00
thorpej 4bdf6bd731 Call mii_down() as appropriate. 1999-11-12 18:14:17 +00:00
thorpej 0ad32f07d2 Revert this part of rev 1.59:
- Be more conservative when resetting the interface after a transmit error.

It caused the interface to totally wedge on the (somewhat common) transmit
FIFO underrun condition.

enami fc21ddd943 Call epstop at the beginning of epinit, especially to make sure that
ep_tick is untimeouted before new one is scheduled.  This makes 3C574-TX
works at least in 10Mb/s mode.

thorpej 5082673b91 - Encapsulate the EEPROM reading code into ep_read_eeprom(), and use
the correct "read eeprom" opcode on the RoadRunner (which has a larger
  EEPROM, and thus needs a different opcode to make room for the larger
  offsets).
- Reset and enable the MII before probing for PHYs, and reset and enable
  the MII in epinit().
- Be more conservative when resetting the interface after a transmit error.

Based on PR #8331, from Ryoji KATO.

Closer on 3c574, probably will work fine with the 3CCFEM556BI (which
won't have an older rev TDK Semi PHY, and which was tested by the author
of the PR).

thorpej f98d358a1f Rework layer 2 protocol input routines. Instead of calling e.g. ether_input()
directly, call the function pointer (*if_input)(ifp, m).  The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary.  Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.

jonathan 055b827e11 Calling DELAY() during polling for command completion of the normal
per-packet discard of every received packet increases latency and
decrease throughput.  INstead, Spin on S_COMMAND_IN_PROGESS for enough
iterations as the expected time to completion.  Only do DELAY()/poll
loops (as suggested by Jason Thorpe) if spinning fails.
Take PCI as fastest case and compute worst-case estimate.

Shorten DELAY() in S_COMMAND_COMPLETE polling-loop up 10, loop-count
down.  to speed up epreset() completion (m/c filter change, ifup/ipdown, etc).

jonathan 07c7535688 * Make doubly sure that the ep shutdownhooks are run at splnet() or above.
* Clear the `enabled' bit in the softc so late hardware interrupts
  (e.g., just after the full reset) done as part of shutdown) are dropped.
* Eliminate loops that  poll forever on S_COMMAND_IN_PROGRESS to complete.
  Add inline function with bounded loopcount plus small delay, to avoid
  bugs in EISA hardware which never sets S_COMMAND_IN_PROGRESS.
  Use for both TX_RESET/RX_RESET/GLOBAL_RESET cmds, and polling for
  discard-Rx completion

jonathan 2bf9a70e67 Endian-ness bugfix for elink3 on big-endian hosts.
Big-endian CPUs should use bus_space_{read,write}_multi_stream methods
  to PIO packet data to NIC in 16-bit or 32-bit chunks.
  Make it so.
  Since we don't have stream methods on all ports yet (esp. i386), use
  the bus_space_{read,write}_multi methods if the compile-time
  stream-method feature-test   macro is not set.
Originally from tsubai@netbsd.org, via HAYAKAWA koichi's cardbus patches.

thorpej f3bfb08d45 When determining the default media on the Vortex/Boomerang, don't pick
the full-duplex variant.  XXX We should check the EEPROM for "default to
full-duplex".
1998-08-28 18:16:02 +00:00
thorpej bc21c243cd For non-MII Vortex/Boomerang, set full-duplex in the MAC CONTROL register
in epsetmedia() if full-duplex is selected (new feature on these cards!)

On MII Boomerangs, set the full-duplex bit in MAC CONTROL in the statchg
callback from the MII layer.  Should fix full-duplex on these cards.

thorpej b170caf730 Completely rewrite media selection. Add support for the MII/PHY on
the 3Com 3c905-TX and 3c905-T4.  Fix handling of the MII on the
3c595-MII and 3c597-MII (can't talk to the PHYs on these cards; just
use "manual" for the external MII port).

Fixes kern/4782 (Chris Demetriou).

jonathan dbf4f7b71f * Tidy PHY [sic] selection code in epsetmedia().
* epinit() had both explicit xcvr selection for 3c589 and a call
  to epsetmedia().  The first is redundant; delete it, and EP_COAX_DEFAULT.

* Update comments to reflect 3c589 and 3c509B fixes.  Fix typos.

veego a2e1f15ba7 - Replace the check for EP_BUS_PCMCIA in epsetmedia with a check for

  and still works with the 3c589.

is 07b064e02e New ARP system, supports IPv4 over any hardware link.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

jonathan c7cec27edf Move if_ep media-sense code from front ends to inside back end,
to prepare for if_media, and to support EISA 3c59x cards:

  * change epconfig() to take a short that encodes the chipset
    type (3c509, or Demon/Vortex/Boomerang).
  * add  distinct 3c509 and Demon/Vortex/Boomerang media-sense
    functions to back end.
  * Add EISA match/attach support for the 3c592 and 3c597
    (Demon) cards as well as the 3c509-comatibl EISA 3c509/3c579.

  * Assume that ISA and ISA PnP cards are 3c509-style, until
    proof to the contrary (e.g. large packet support).

Tested on 3c595, 3c590, and 3c509b. Not tested on 3c515 or Demon.

jonathan 4fdff0ed65 * Add ep_complete_cmd() function, to issue commands that perform a reset
(RX_RESET, TX_RESET, GLOBAL_RESET).
  Commands issued while a reset is in progress may be dropped. The driver
  must wait until resets are complete; ep_complete_cmd() does so.
* Change RX_RESET,  TX_RESET, GLOBAL_RESET to use ep_complete_cmd().

* Revert epconfig() to use inline RX_RESET, TX_RESET.
  That avoids accidentally setting IFF_UP, which  breaks both diskless boot,
  and "halt" commands issued before the interface is brought up.
1997-02-16 04:09:18 +00:00
jonathan 9821b30fe4 Use DELAY() after doing a TX_RESET or RX_RESET command.
Newer boards (e.g., Vortex) take  time to reset, and wedge on some machines.
Polling on S_COMMAND_IN_PROGRESS would be better, but that doesn't
work with xx_RESET commands on 3c509s.
