Subject: net: dsa: qca8k: add additional MIB counter and make it dynamic
|
|
|
|
We are currently missing 2 additionals MIB counter present in QCA833x
|
|
switch.
|
|
QC832x switch have 39 MIB counter and QCA833X have 41 MIB counter.
|
|
Add the additional MIB counter and rework the MIB function to print the
|
|
correct supported counter from the match_data struct.
