NAME
enum_ieee80211_hw_flags - hardware flags
SYNOPSIS
enum ieee80211_hw_flags {
IEEE80211_HW_HOST_GEN_BEACON_TEMPLATE,
IEEE80211_HW_RX_INCLUDES_FCS,
IEEE80211_HW_HOST_BROADCAST_PS_BUFFERING,
IEEE80211_HW_2GHZ_SHORT_SLOT_INCAPABLE,
IEEE80211_HW_2GHZ_SHORT_PREAMBLE_INCAPABLE
};
CONSTANTS
- 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 donīt 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_2GHZ_SHORT_SLOT_INCAPABLE
- Hardware is not capable of short slot operation on the 2.4 GHz
band. - IEEE80211_HW_2GHZ_SHORT_PREAMBLE_INCAPABLE
- Hardware is not capable of receiving frames with short preamble on the 2.4 GHz band.
DESCRIPTION
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 doesnīt need setting any particular flags. There are
some exceptions to this rule, however, so you are advised to review
these flags carefully.
