Re: [Etherboot-developers] Prism2 driver update?

[Boris <bo...@th...>]

The latest linux-wlan-ng is 0.1.15pre8, Looking at the changelog
[ftp://ftp.linux-wlan.org/pub/linux-wlan-ng/CHANGES], a few updates have
happened that I noticed since 0.1.13
- Applied pizza's patch to remove the pb_t structure and make all
    802.11<->ether conversions happen in-place.  Noticeably reduces
    cpu load.  Also includes a few misc bugfixes to the conversion code.
- Partial rewrite of the PCI/PLX/USB driver internals
- Fix an alignment bug in the rx path.
- Partial rewrite of copy_to_bap.
- More cleanups/deletions/fixes in wlan_compat.h
- Updates to hfa384x.h to reflect latest documentation

and David Gibson [the author and maintainer of the orinoco linux driver] has
a sept 13 update [http://ozlabs.org/people/dgibson/dldwd/]

Hope this helps out. :)
