5.1.3. Maximum Response Code
The Maximum Response Code field specifies the maximum time allowed
before sending a responding Report. The actual time allowed, called
the Maximum Response Delay, is represented in units of milliseconds,
and is derived from the Maximum Response Code as follows:
If Maximum Response Code < 32768,
Maximum Response Delay = Maximum Response Code
If Maximum Response Code >=32768, Maximum Response Code represents a
floating-point value as follows:
0 1 2 3 4 5 6 7 8 9 A B C D E F
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|1| exp | mant |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
Maximum Response Delay = (mant | 0x1000) << (exp+3)
5.1.9. QQIC (Querier's Query Interval Code)
The Querier's Query Interval Code field specifies the [Query
Interval] used by the Querier. The actual interval, called the
Querier's Query Interval (QQI), is represented in units of seconds,
and is derived from the Querier's Query Interval Code as follows:
If QQIC < 128, QQI = QQIC
If QQIC >= 128, QQIC represents a floating-point value as follows:
0 1 2 3 4 5 6 7
+-+-+-+-+-+-+-+-+
|1| exp | mant |
+-+-+-+-+-+-+-+-+
QQI = (mant | 0x10) << (exp + 3)
-- rfc3810
#define MLDV2_QQIC(value) MLDV2_EXP(0x80, 4, 3, value)
#define MLDV2_MRC(value) MLDV2_EXP(0x8000, 12, 3, value)
Above macro are defined in mcast.c. but 1 << 4 == 0x10 and 1 << 12 == 0x1000.
So the result computed by original Macro is larger.
