Improve performance in l3 submode
Two cases where performance has been improved
- When using a gateway from a routing table (l3 submode),
store the mac within the next hop table, to avoid a hash_lookup.
This gives ~10% improvement.
- Read tsc only once per bulk (of up to 64 packets).
This gives ~10% improvement to swap, 4% to gen.
In addition a small fix has been added, preventig "No route" Error
to be written too aften.
