Subject: [PATH backport 2/2] mlxsw: reg: Limit MTBR register records buffer by
|
|
one record
|
|
|
|
The MTBR register is used to obtain specific cable status, so just only
|
|
one data record is required in transaction.
|
|
|
|
Limit size of MTBR register to avoid sending redundant size of buffer
|
|
to firmware.
