LRO aka TPA and jumbo frame support uses aggregation ring for placing
Rx buffers. These features can generate multiple Rx completions for a
single Rx packet. Increase size of Rx Completion Queue to handle TPA
and aggregation ring events.

Reset mbuf->data_off before handing the Rx packet to the application.
We were not doing this in the TPA path. It can cause applications
using this field for post processing to work incorrectly.
