Subject: [PATCH 02/14] net: dsa: qca8k: make mib autocast feature optional
|
||
|
|
|
||
|
|
Some switch may not support mib autocast feature and require the legacy
|
||
|
|
way of reading the regs directly.
|
||
|
|
Make the mib autocast feature optional and permit to declare support for
|
||
|
|
it using match_data struct in a dedicated qca8k_info_ops struct.
