Subject: [PATCH 105/189] net/hns3: fix PTP capability report
|
||
|
|
|
||
|
|
The PTP depends on special packet type reported by hardware which
|
||
|
|
enabled rxd advanced layout, so if the hardware doesn't support rxd
|
||
|
|
advanced layout, driver should ignore the PTP capability.
|
||
|
|
|
||
|
|
Fixes: 438752358158 ("net/hns3: get device capability from firmware")
