thorpej b84f740be0 Move bpfattach()/bpfdetach() calls into ether_ifattach()/ether_ifdetach(). 2000-11-15 01:02:11 +00:00
thorpej 7ca3fb9ef0 Move the check for "promisc + unicast + not for us" into ether_input(),
and change Ethernet drivers to always pass all received frames to
ether_input() (with a few exceptions, which are documented in the
code).

thorpej 7951ece147 Use splsched() instead of splhigh(), and explain why in a comment,
as well as document a pitfall of the approach being used.

jhawk 1e59d99d28 For all network drivers that call ether_ifattach(), and also
have _detach() functions:
  Ensure that softc keeps state about whether the attach succeeded,
  and make the detach function return immediately if the attach did
  not complete.

martin 41dc1a6839 Avoid stomping on the W0_CONFIG_CTRL register which seems not to be
implemented on EISA cards. This makes a 3Com 3C597 Fast Etherlink TX
work for me at last, fixing PR kern/7067.

augustss 169ac5b3c1 Remove register declarations. 2000-03-30 12:41:09 +00:00
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.

thorpej a6f861574a No longer necessary to futz with ifp->if_baudrate here. 2000-03-06 21:02:00 +00:00
itojun 1ccb9e8170 when change mbuf type, clear m_pkthdr so that we do not get panic with
old data in pointer fields.  NOTE: we'll extend m_pkthdr field soon.

Wondering: do mbuf pre-allocation code in elink3.c really buy us much
performance?  it comes with code duplicate/synchronization problem with
sys/mbuf.h...

enami c7573d517e - Bail out from attach stage if failed to enable card, number of iospace
or memspace is unexpected, failed to map iospace or failed to configure
the controller properly.
- Disestablish an interrupt handler if failed to enable card.

flags down from the parent to child vi mii_attach().

augustss 82559ba682 Move detach operations around a little to simplify (and perhaps get it
right?).  Prompted by Jason, itojun and myself.

"conventions".

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.

specific, move them into the chipset drivers.

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).
