Hyong Youb Kim ed933c35ca net/enic: add the simple version of Tx handler
Add a much-simplified handler that works when all offloads are
disabled, except mbuf fast free. When compared against the default
handler, under ideal conditions, cycles per packet drop by 60+%.
The driver tries to use the simple handler first.

The idea of using specialized/simplified handlers is from the Intel
and Mellanox drivers.
