From afbf30a2b78cac38e6ddae10a73063943b4783ee Mon Sep 17 00:00:00 2001 From: James Ketrenos Date: Thu, 25 Aug 2005 00:05:33 -0500 Subject: Catch ipw2200 up to equivelancy with v1.0.5 * Fixed #452 problem with setting retry limit (thanks to Hong Liu) * Fixed #592 race condition during association causing firmware errors * Fixed #602 problem with building in 64-bit environment * Fixed #625 problem with SCAN_REQUEST_EXT sometimes failing * Fixed #645 problem with bit rate not decreasing when moving laptop farther from AP * Fixed #656 problem with 'iwconfig eth1 mode auto' and 'modprobe' locking the system * Fixed #667 problem with "No space for Tx" for hwcrypto=1 * Fixed #685 kernel panic in rmmod caused by led work is still queued * Fixed #695 problem with network doesn't reassociate after suspend/resume * Fixed #701 problem with 'iwprvi sw_reset' not resetting the card from monitor mode * Fixed #710 problem with monitor mode being used after a WEP key has been configured * Fixed network->mode vs. priv->ieee->iw_mode checking (thanks to Ben Cahill) * Fixed "Unknown management packet %d" warning * Fixed setting channels multiple times in monitor mode causes scan stopped * Fixed ipw_wx_sw_reset doesn't switch firmware if mode is changed. * Add duplicate packet checking code (kill ping DUP! and TKIP replay warning) * Fix hardware encryption (both WEP and AES) doesn't work with fragmentation.
