Description (partial)

Upstream throughput is affected when using DPON.
It seems that the random drop is less apparent after a few days if the modem are stable (staying online)

Currently seen on a MC20x20/MC3G60. For 88V/520, if we enabled 'cable upstream rate-limit-bwreq' and 'dpon', it will be also affected.
