improvement on PPP recovery, to avoid sleep state concerns.
changed PPP pings from 60s(pingint)+10s(pingint2)*5(ip2count) tries to 60s(pingint)+5s(pingint2)*10(ip2count tries, correspondingly in FW c=5 d=5 to c=10 d=10
added r_addr and l_addr for consistency
turned ping2cont OFF, to be default as it did nothing.
