From 6eb18137643fee5f182d85c818062b4feddfb76b Mon Sep 17 00:00:00 2001 From: Dedy Lansky Date: Sun, 8 Feb 2015 15:52:03 +0200 Subject: cfg80211: add bss_type and privacy arguments in cfg80211_get_bss() 802.11ad adds new a network type (PBSS) and changes the capability field interpretation for the DMG (60G) band. The same 2 bits that were interpreted as "ESS" and "IBSS" before are re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid values are: "IBSS", "PBSS" (new) and "AP". In order to get the BSS struct for the new PBSS networks, change the cfg80211_get_bss() function to take a new enum ieee80211_bss_type argument with the valid network types, as "capa_mask" and "capa_val" no longer work correctly (the search must be band-aware now.) The remaining bits in "capa_mask" and "capa_val" are used only for privacy matching so replace those two with a privacy enum as well.
