New Revision: 268233
URL: http://svnweb.freebsd.org/changeset/base/268233

Log:
  Initialize the switch vlan table at attachment.
  
  Update some comments on code, specifying the correct vlans used on switch
  setup.
  
  Advertise the proper switch operation mode (the rtl8366rb only support
  dot1q vlans).
  
  This fixes the breakage that i introduced on r249752 and make the rtl8366rb
  switch works again with etherswitchcfg(8).
  
  Tested on TP-Link 1043ND.
  
  Tested by:	me, Harm Weites (harm at weites.com)
