855590bfe7 mge(4): fix two bugs, which were leading to crash/hang under very heavy
network load.

1. Leave the RX interrupt routine if there is no mbuf available.

2. Properly initialize and track tx_desc_used_count counter so as not to
leak mbuf while traversing used descriptors.

15ccf24786 Handle mge(4) chip revision differences at run-time rather then compile time,
which is more flexible for future revisions, and lets eliminate some #defines
and compile conditionals.
