[ECOS] How to correctly run SMSC LAN91C111 Driver by interrupt

["ariga masahiro" <ariga@link-lab.co.jp>]

Hi everyone,

Someone please help me.

I am trying to run SMSC LAN91C111 Ethernet Driver by interrupt
on own board.

I studied source if_lan91cxx.c and found next switching context

#ifndef CYGPKG_IO_ETH_DRIVERS_STAND_ALONE,

and concluded I must make CYGPKG_IO_ETH_DRIVERS_STAND_ALONE  '0'
in order to regisiter ISR etc.

I registered ISR into Vector Table.

When I Built,I confronted next errors.
/ecos-c/cygwin/home/LINK/inserter20070529-1_interrupt/untitled_install/lib/extras.o: 
In function `do_exec':
/opt/ecos/ecos-2.0/packages/hal/sh/arch/v2_0/src/redboot_linux_exec.c:114: 
undefined reference to `_eth_drv_dsr'
/opt/ecos/ecos-2.0/packages/hal/sh/arch/v2_0/src/redboot_linux_exec.c:83: 
undefined reference to `_eth_drv_funs'

I infered they are concerned with eth_drv.c,and found eth_drv.c was included 
in next three directotries in eCos source tree.
C:/cygwin/opt/ecos/ecos-2.0/packages/io\eth/v2_0/src/lwip/eth_drv.c
C:/cygwin/opt\ecos/ecos-2.0/packages/io\eth/v2_0/src/net/eth_drv.c
C:/cygwin/opt/ecos/ecos-2.0/packages/io\eth/v2_0/src/stand_alone/eth_drv.c

I am convinced that because I did not compile stand_alone,I confronted the 
errors.

So,first I tried to include /net/eth_drv.c.
I found in order to include /net/eth_drv.c I must make CYGPKG_NET available.
Then I was stuck in the mud.
I confronted Conflicting Errors continuously and couldn't even build 
redboot.
I abandoned.

Then, I next tried to include /lwip/eth_drv.c.
In order to do that,I changed option parameter a bit.
I commented "active_if" line.

cdl_component CYGPKG_IO_ETH_DRIVERS_LWIP
##        active_if     CYGPKG_NET_LWIP

Then I could include /lwip/eth_drv.c,
but confronted next errors.
src/lwip/io_eth_eth_drv.o 
/opt/ecos/ecos-2.0/packages/io/eth/v2_0/src/lwip/eth_drv.c
/opt/ecos/ecos-2.0/packages/io/eth/v2_0/src/lwip/eth_drv.c:70:29: 
cyg/kernel/kapi.h: No such file or directory
/opt/ecos/ecos-2.0/packages/io/eth/v2_0/src/lwip/eth_drv.c:89: parse error 
before "delivery"
/opt/ecos/ecos-2.0/packages/io/eth/v2_0/src/lwip/eth_drv.c:89: warning: type 
defaults to `int' in declaration of `delivery'

I am in predicament.

Please enlighten me what is correct way to run SMSC LAN91C111 Ethernet 
Driver by interrupt.
