From b16a228d05a95b27d77d07a91688382f68ece8a7 Mon Sep 17 00:00:00 2001 From: "simon@thekelleys.org.uk" Date: Sun, 30 Oct 2005 15:50:15 +0000 Subject: [PATCH] Atmel wireless update * Merge PCMCIA card table with new Brodowski PCMCIA id table. * Add missing entries to PCMCIA id table. * Other tweaks to conform with Documentation/driver-changes.txt (types, call request_region, etc) * Fix size of requested IO region. * Reduce printk verbosity. * Remove EXPERIMENTAL * tweak to association code - don't force shared key authentication when wep in use.
