[PATCH] mac80211: renumber and document the hardware flags
Currently, hardware flags that drivers must set are not documented well enough. Fix this. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Michael Wu <flamingice@sourmilk.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

+/**
+ * enum ieee80211_hw_flags - hardware flags
+ *
+ * These flags are used to indicate hardware capabilities to
+ * the stack. Generally, flags here should have their meaning
+ * done in a way that the simplest hardware doesn't need setting
+ * any particular flags. There are some exceptions to this rule,
+ * however, so you are advised to review these flags carefully.
+ *
+ * @IEEE80211_HW_HOST_GEN_BEACON_TEMPLATE:
+ * The device only needs to be supplied with a beacon template.
+ * If you need the host to generate each beacon then don't use
+ * this flag and call ieee80211_beacon_get() when you need the
+ * next beacon frame. Note that if you set this flag, you must
+ * implement the set_tim() callback for powersave mode to work
+ * properly.
+ * This flag is only relevant for access-point mode.
+ *
+ * @IEEE80211_HW_RX_INCLUDES_FCS:
+ * Indicates that received frames passed to the stack include
+ * the FCS at the end.
+ *
+ * @IEEE80211_HW_HOST_BROADCAST_PS_BUFFERING:
+ * Some wireless LAN chipsets buffer broadcast/multicast frames
+ * for power saving stations in the hardware/firmware and others
+ * rely on the host system for such buffering. This option is used
+ * to configure the IEEE 802.11 upper layer to buffer broadcast and
+ * multicast frames when there are power saving stations so that
+ * the driver can fetch them with ieee80211_get_buffered_bc(). Note
+ * that not setting this flag works properly only when the
+ * %IEEE80211_HW_HOST_GEN_BEACON_TEMPLATE is also not set because
+ * otherwise the stack will not know when the DTIM beacon was sent.
+ *
+ * @IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED:
+ * Channels are already configured to the default regulatory domain
+ * specified in the device's EEPROM
