boards which use MII for media attachment.
ISV SROM format information lifted from Matt Thomas's `de' driver.
Thanks to Dave Sainty for experimenting w/ his 21140A MII boards, and
for supplying a fix to the MII bit-bang code (PR #8382).
- Only use 16 longword bursts.
- Reset the interface for receive filter setups that don't come from
the reset path.
Hi, Jason is getting really tired of broken clone chips, and really wishes
real 21140 boards were still available, because the DEC chips seem to work
Just Dandy.
support for the ISV SROM format used in the 2114{1,1A,2,3}. Note, like
the 21040, auto-sense is not yet supported for the 21041.
Add a "pre-init" hook, which will be used for the 2114x and PNIC (currently)
which allows chip-specific code to set up and write OPMODE before the
chip is reset. This is necessary in order for the chip's internal
pathways to get initialized properly for MII/SYM/PCS/SIA media attachments.
Thanks to Dave Sainty for the hint from the `de' driver that inspired the
pre-init hook.
- Fix the SROM checksum routine.
- Add code to parse the old DEC Address ROM SROM format.
- Rearrange the statchg routines a bit, to make them consistent with one
another.
- Add support for the DECchip 21040. XXX No support for media autosense
yet, and no support for any of the multi-port boards yet.
Tree structure:
- sys/arch/sh3: sh3 generic code
As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)
Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).
Drop multicast/broadcast packet looped back from myself.
This is to cope with SMC91C92 (Megahertz XJ10BT), which
loops back multicast packet to itself on promiscuous mode.
(should be ensured by chipset configuration)

put it in Store-and-Forward mode right from the get-go. This eliminates
the DMA underrun errors that prevented the receive filter setup from working
and caused smashed packets to go out onto the wire.
My NetGear FA310-TX board now works.
There are still "filter setup failed to complete" messages, however they
don't appear to indicate that the filter setup actually failed, since
unicast and multicast packet reception work fine. I will address this
problem shortly.
Reading the log for the FreeBSD `pn' driver suggests that these chips are,
in fact, pretty crappy, riddled with hardware bugs (for which more workarounds
are coming).
rewrite of the driver for the DECchip 21x4x Ethernet chips, and a variety
of clones.
Currently, the driver supports the Winbond 89C840F (this works pretty
well), and the Lite-On PNIC (e.g. NetGear PCI boards), however Lite-On
support may be broken [I may simply have a busted test board].
Eventually, support for the Macronix and ASIX chips will filter into
this driver, and then, slowly, support for the genuine DEC chips,
and maybe even the DE-425 EISA model.
and consider it to be like an RCC (receive copy complete). The RCC
code path has always checked for bad received packets.
- Trim the CRC length off the recived packet length; the EPIC/100 always
includes the CRC in the packet.
- Improve fatal error reporting.
