71 * A mode that the chip can be put in. A mode defines a set of constraints on
72 * the interfaces that can exist while in that mode. Modes define a unit of
73 * configuration where all interfaces must be torn down to switch to a
74 * different mode. Some HALs may only have a single mode, but an example where
75 * multiple modes would be required is if a chip has different firmwares with
76 * different capabilities.
78 * When in a mode, it must be possible to perform any combination of creating
79 * and removing interfaces as long as at least one of the
80 * ChipIfaceCombinations is satisfied. This means that if a chip has two
81 * available combinations, [{STA} <= 1] and [{AP} <= 1] then it is expected
82 * that exactly one STA interface or one AP interface can be created, but it
83 * is not expected that both a STA and AP interface could be created. If it
84 * was then there would be a single available combination
85 * [{STA} <=1, {AP} <= 1].
87 * When switching between two available combinations it is expected that
88 * interfaces only supported by the initial combination must be removed until
89 * the target combination is also satisfied. At that point new interfaces
90 * satisfying only the target combination can be added (meaning the initial
91 * combination limits will no longer satisfied). The addition of these new
92 * interfaces must not impact the existence of interfaces that satisfy both
95 * For example, a chip with available combinations:
96 * [{STA} <= 2, {NAN} <=1] and [{STA} <=1, {NAN} <= 1, {AP} <= 1}]
97 * If the chip currently has 3 interfaces STA, STA and NAN and wants to add an
98 * AP interface in place of one of the STAs then first one of the STA
99 * interfaces must be removed and then the AP interface can be created after
100 * the STA had been torn down. During this process the remaining STA and NAN
101 * interfaces must not be removed/recreated.
103 * If a chip does not support this kind of reconfiguration in this mode then
104 * the combinations must be separated into two separate modes. Before
105 * switching modes all interfaces must be torn down, the mode switch must be
106 * enacted and when it completes the new interfaces must be brought up.
