Subject: [PATCH net-next 2/4] tg3: Adjust BD replenish thresholds

The BD replenish thresholds for the 57765 and newer ASIC revs are a
little strict.  They were tuned for a mode that is currently unused.
This patch relaxes the thresholds so that they are set to values more
inline with the resources available.
