   4 Subject: [PATCH 09/15] net: dsa: mt7530: define MAC speed capabilities per
   5  switch model
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit
   9
  10 With the support of the MT7988 SoC switch, the MAC speed capabilities
  11 defined on mt753x_phylink_get_caps() won't apply to all switch models
  12 anymore. Move them to more appropriate locations instead of overwriting
  13 config->mac_capabilities.
  14
  15 Remove the comment on mt753x_phylink_get_caps() as it's become invalid with
  16 the support of MT7531 and MT7988 SoC switch.
  17
  18 Add break to case 6 of mt7988_mac_port_get_caps() to be explicit.
