The attribute specifies how many retries should be made to get the
Multicast Forward VC setup. The LEC will retry after
wflecMulticastFwdTimeout seconds and will double this timeout for each
each retry which follows. The timeout will not exeed 30 seconds however.
After wflecMulticastFwdRetry retries, the LEC will restart itself. If
wflecMulticastFwdRetry is set to 0 it will retry the BUS phase forever
and will never restart itself.
