Dear all,
I had posted this problem on the hostap list:
http://lists.shmoo.com/pipermail/hostap/2004-March/006018.html
Pavel Roskin briefly answered my question on the same list:
http://lists.shmoo.com/pipermail/hostap/2004-March/006025.html
and told me about the linux-pcmcia list. Pavel also mentioned about the
availability of a working patch:
http://ritz.dnsalias.org/linux/pcmcia-ti-routing-8.patch
which is apparently for 2.6 kernel, whereas I am developing on a 2.4
kernel. I have just skimmed through the recent posts about the TI bridges
to find a 2.4 patch.
Could anyone guide me with the appropriate correction?
PS. I would like to test the patch on my system hosting the TI card, whose
pci info is below:
