Revision 98bda63e20daab95bdc084ce00459a4f622a0505 authored by Roman Kiryanov on 19 February 2020, 21:40:06 UTC, committed by David S. Miller on 20 February 2020, 23:02:02 UTC
The description says 'If unsure, say N.' but the module is built as M by default (once the dependencies are satisfied). When the module is selected (Y or M), it enables NETFILTER_FAMILY_BRIDGE and SKB_EXTENSIONS which alter kernel internal structures. We (Android Studio Emulator) currently do not use this module and think this it is more consistent to have it disabled by default as opposite to disabling it explicitly to prevent enabling NETFILTER_FAMILY_BRIDGE and SKB_EXTENSIONS.
