URL: https://svnweb.freebsd.org/changeset/base/295876

Log:
  hyperv/hn: Staticize and rename packet TX done function
  
  It is only used in hv_netvsc_drv_freebsd.c; and rename it to hn_tx_done()
  mainly to reserve "xmit" for ifnet.if_transmit implement.
  
  While I'm here, remove unapplied comment.
