[Avila] IXP 400 Access Libary and Ethernet Drivers

[Tim Harvey]

Joel,=0A=0AI'm also not fond at all of snapgear... its very outdated and no=
t supported (its free :) ).  I have no experience with uClibc as all of my =
work has been using glibc.  Do you really need uClibc and does it really of=
fer a large space/footprint savings?  I would love to see a good modern com=
parision of glibc vs uClibc.  I've had no difficulties building the latest =
wireless-tools with glibc and the GW BSP.=0A=0AI haven't bothered trying to=
 move to a better build system for my projects because of the difficulty I =
had before the latest GW BSP when I had to integrate the IAL myself into th=
e kernel.  Over time I've added so many external packages to my build tree,=
 its not very 'snapgear' anymore :)=0A=0ATim =0A=0A----- Original Message -=

e used the snapgear distribution that you are speaking of, and though I=0Ad=
idn't find it as flexible as buildroot, it worked fairly well.  The big=0Ap=
roblem is that some of the packages are a little outdated and had to be=0Au=
pdated, and this is more of a pain with snapgear than with buildroot.=0A=0A=
I would be totally happy to stick with snapgear as I have my whole platform=
=0Aup and running perfectly but compiled against libc.  I want to compile=
=0Aagainst uClibc and I have been having a bugger of a time compiling 1 pac=
kage=0AI absolutely must have with snapgear/uclibc.  The package is wireles=
s tools=0Aand with either the one that comes with the snapgear distribution=
 or the=0Alatest version, I can compile against uClibc with no problem but =
I can't=0Aactually run the binary because it seems to still be looking for =
the libc=0Alibrary (when it was compiled against uClibc)=0A=0ASince I haven=
't been able to fix the snapgear problem (have a support=0Arequest on uClin=
ux message boards), I thought I would try to switch to=0Abuildroot which ha=
s gone fairly smoothly except for this issue.  I would be=0Ahappy with some=
 advice on either problem so I can complete the project and=0Abe done with =
it :)=0A=0AJoel=0A=0A-----Original Message-----=0AFrom: Tim Harvey [mailto:=

Wow, looks like your going through a lot of uncessesary thrash.  Why don't=
=0Ayou just use the BSP that Gateworks supplies for their boards?  Its read=
y to=0Ago (although the 2.6.x kernel is 2.6.15-uc0, but quite frankly I'm n=
ot sure=0AI understand the constant desire to keep up with the absolute lat=
est=0Akernel).=0A=0AThe answer to your question is yes - if you want to use=
 the ENET you have to=0Ahave the IntelAccess Library (or equivalent 'driver=
' code for the internal=0ANetwork Processing Engines or NPE's).  Think of t=
he NPE's as a 'soft-mac'=0Afor lack of a better term.  The reason you are g=
oing through all this thrash=0Ais that Intel, in their infinite wisdom will=
 not release their library to=0Athe GPL which keeps it from being integrate=
d into the Linux kernel.  There=0Ais some work on an opensource, reverse en=
gineered?, GPL driver to solve this=0Aissue, but I haven't followed that mu=
ch.=0A=0AThe Gateworks BSP, and possibly some of the other third party BSP'=
s=0Asupporting avila, keeps you from having to go through this thrash becau=
se it=0Asupplies a kernel pre-patched with the IAL.=0A=0ATim=0A=0A=0A----- =
