   4 Subject: [PATCH] net: dsa: ocelot: add NET_VENDOR_MICROSEMI dependency
   5
   6 Selecting MSCC_OCELOT_SWITCH is not possible when NET_VENDOR_MICROSEMI
   7 is disabled:
   8
   9 WARNING: unmet direct dependencies detected for MSCC_OCELOT_SWITCH
  10   Depends on [n]: NETDEVICES [=y] && ETHERNET [=n] && NET_VENDOR_MICROSEMI [=n] && NET_SWITCHDEV [=y] && HAS_IOMEM [=y]
  11   Selected by [m]:
  12   - NET_DSA_MSCC_FELIX [=m] && NETDEVICES [=y] && HAVE_NET_DSA [=y] && NET_DSA [=y] && PCI [=y]
  13
  14 Add a Kconfig dependency on NET_VENDOR_MICROSEMI, which also implies
  15 CONFIG_NETDEVICES.
  16
  17 Depending on a vendor config violates menuconfig locality for the DSA
  18 driver, but is the smallest compromise since all other solutions are
  19 much more complicated (see [0]).
