config IWLWIFI_BCAST_FILTERING
bool "Enable broadcast filtering"
depends on IWLMVM
help
Say Y here to enable default bcast filtering configuration.
Enabling broadcast filtering will drop any incoming wireless
broadcast frames, except some very specific predefined
patterns (e.g. incoming arp requests).
If unsure, don't enable this option, as some programs might
expect incoming broadcasts for their normal operations.
