Subject: [PATCH 643/660] net: sfp: remove incomplete 100BASE-FX and 100BASE-LX
|
|
support
|
|
|
|
The 100BASE-FX and 100BASE-LX support assumes a PHY is present; this
|
|
is probably an incorrect assumption. In any case, sfp_parse_support()
|
|
will fail such a module. Let's stop pretending we support these
|
|
modules.
