From 823283549da144ff49e65c6e4a670b7784203e0b Mon Sep 17 00:00:00 2001 From: James Ketrenos Date: Wed, 24 Aug 2005 22:33:31 -0500 Subject: [PATCH] Catch ipw2100 up to equivelancy with v1.1.1 * Added WE-18 support. This allows the use of -Dext with wpa_supplicant > 0.4.x (thanks to Hong Liu) * Fixed #339 problem with iwconfig set/get txpower (thanks to Hong Liu) * Fixed #598 problem when with error messages when module loaded with 'disable=1' (thanks to Hong Liu) * Fixed #640 problem with 'iwlist retry' now showing min/max retry * Fixed compatibility with wpa_supplicant and the new -Dipw interface (that included a fix for 64-bit compatibility) * Added CFG_CRC_CHECK which allows passing through packets with bad CRCs while in monitor mode.
