net/enic: optimize the Tx function

Reduce host CPU overhead of Tx packet processing:
* Use local variables inside per-packet loop instead of fields in structs.
* Factor book keeping and conditionals out of the per-packet loop where
  possible.
* Post buffers to the nic at a maximum of every 64 packets
