@ -1247,6 +1247,28 @@ N.B. the accuracy of the timing used to wait for the replies is
---------
Default:
$mcastretries = 0;
Set $mcastretries to the number of times to retry the multicast
If $mcastexpect is 0, this is simply the number of extra times
that it will send the multicast request
N.B. cgminer doesn't listen for multicast requests for 1000ms after
each one it hears
If $mcastexpect is > 0, it will stop looking for replies once it
has found at least $mcastexpect rigs, but it only checks this rig
limit each time it reaches the $mcasttimeout limit, thus it can find
more than $mcastexpect rigs if more exist
It will send the multicast message up to $mcastretries extra times or
until it has found at least $mcastexpect rigs
However, when using $mcastretries, it is possible for it to sometimes
ignore some rigs on the network if $mcastexpect is less than the
number of rigs on the network and some rigs are too slow to reply
---------
Default:
$allowgen = false;
