commit 70172a73a90d1d12157a7ee99350275a68a4f57d
Author: Sepherosa Ziehau <sephe at dragonflybsd.org>

    emx(4): Compact transmit path a little bit
    - emx_buf.m_head is only set/cleared in the last emx_buf associated with
      the packet, so we don't need to keep clearing it in transmit descriptor
      setup loop.
    - Used transmit descriptors do not need to be cleared in txeof and tx_collect
