Subject: [PATCH 16/21] net: phylink: require supported_interfaces to be filled
|
||
|
|
|
||
|
|
We have been requiring the supported_interfaces bitmap to be filled in
|
||
|
|
by MAC drivers that have a mac_select_pcs() method. Now that all MAC
|
||
|
|
drivers fill in the supported_interfaces bitmap, it is time to enforce
|
||
|
|
this. We have already required supported_interfaces to be set in order
|
||
|
|
for optical SFPs to be configured in commit f81fa96d8a6c ("net: phylink:
|
||
|
|
use phy_interface_t bitmaps for optical modules").
|
||
|
|
|
||
|
|
Refuse phylink creation if supported_interfaces is empty, and remove
|
||
|
|
code to deal with cases where this mask is empty.
