thorpej 9ec2341af3 Add support for jumbo Ethernet frames on the DP83820. 2001-07-07 02:32:38 +00:00
thorpej 4f9dcdfb8a Split the receive interrupt handler into two versions, one for the
SiS900/DP83815, one for the DP83820.  In preparation for changes
to the DP83820 version for handling jumbo Ethernet frames.

thorpej ca4d373730 Implement support for IP/TCP/UDP checksum offloading provided by
network interfaces.  This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us.  In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software.  This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.

We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.

Note: hardware-assisted checksumming defaults to "off".  It is
enabled with ifconfig(8).  See the manual page for details.

Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.

thorpej f1f78293df - Add some instrumentation which can be enabled by defining
SIP_EVENT_COUNTERS.
- Decrease SIP_NTXSEGS to 8 and increase SIP_TXQUEUELEN to 256.
  This gives us 256 transmit jobs with only twice the descriptor
  memory footprint.  This prevents stalling transmissions due to
  lack of transmit jobs under heavy load.
- Increase SIP_NRXDESC to 128 so we don't run out of receive descriptors
  under extreme load.
- As recommended by the manual, leave one descriptor in the transmit ring
  with OWN clear to prevent wrap-around.
- Even though the manual claims that driver software must initialize
  TXDP if there are no pending transmissions when a new transmission
  is to be initialized, doing so causes serious performance degredation
  on the DP83820 under heavy load.  Not initializing TXDP also increases
  performance on the DP83815.

All of this gets us up to ~90Mb/s on both the DP83820 and DP83815 when
connected to a 100base network.

thorpej dbdf3820d8 Add a driver for the National Semiconductor DP83820 Gigabit Ethernet
chip.  This is found on the NetGear GA-622 and Asante FriendlyNet
GigaNIX.

thorpej 38c798fe9f Encapsulate name declarations in macros in preparation for adding
conditionally-compiled code for the DP83820.

briggs 2dbd96c75c There is no need to accept all ARP packets (regardless of destination
address) on the DP83815.  Noted by Shiva Shenoy <shiva@riverstonenet.com>
in private correspondence.

briggs 75a60f539a More fixes for the DP83815...
- Set the destination address register properly for "perfect match" mode
  in the receive filter setup.
- Do not enable multicast receipt unless we are configured for some multicast.
- Use the "recommended settings" (which set undocumented registers and
  documented-as-reserved fields) for the silicon revision 302h (not 203h,
  as documented in one of the two places in the manual) because the
  documentation is unclear and because those settings fix the card's
  behavior in "perfect match" mode.  Without those settings, the card
  was generating random CRC/invalid symbol errors and generally not
  working unless it was set to be promiscuous.

With these changes, this week's version of the Netgear FA311 works for me.

briggs 77a57bede4 Add a variant hook to read the ethernet MAC address from EEPROM differently
for the SiS 900 and the DP83815.  Also add some configuration suggested by
the DP83815 documentation for one model of the DP83815.

thorpej d1a5dabcc9 Gack, fix a stupid bug in the DP83815 multicast setup code. 2001-02-06 02:49:12 +00:00
sommerfeld 851de295eb Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

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 e925979f9b Preliminary support for the National Semiconductor DP83815 10/100
Ethernet chip, which is based on the SiS 900 core, but with differences
in the PHY and filter programming interface, and different WoL and
802.3x flow control programming.

This chip appears on new NetGear FA-312TX cards.  Thank goodness
they're finally ditching the LiteOn chips.

tsutsui 23830f1e6c - Check CR_RST rather than ISR_TXRCMP and ISR_RXRCMP in sip_reset()
- Add more delay after reset
- "Big endian mode" on SiS 900 seems broken so don't enable it;
  use htole32()/le32toh() instead
- Don't cast u_int16_t array to u_int8_t pointer
- Add some delay() to FILTER_EMIT macro in sip_set_filter()

Now SiS 900 works on my macppc.

mycroft d07e505604 Rather than guessing at the location of the PMCSR, use the pointer returned by
pci_get_capability().  (This is, after all, a standardized interface...)

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 ca9b9a3b2e Adapt to mii_phy_probe() change. 1999-11-04 00:24:00 +00:00
thorpej 4bd8f1566c Be a little nicer about memory usage:
* Don't allocate receive buffers until the interface is actually brought
  up, and release all of them if the interface is taken down.
* Add a knob (defaults to off) which will copy an incoming packet to
  a single header mbuf if it is small enough to fit in one, rather than
  burning an entire cluster on it.  Note that this change will be mostly
  moot if/when sbcompress() it changed to handle compressing clusters.
