Subject: [PATCH] net: phy: realtek: clear master_slave_state if link is down
|
|
|
|
rtlgen_decode_physr() which sets master_slave_state isn't called in case
|
|
the link is down and other than rtlgen_read_status(),
|
|
rtl822x_c45_read_status() doesn't implicitely clear master_slave_state.
|
|
|
|
Avoid stale master_slave_state by always setting it to
|
|
MASTER_SLAVE_STATE_UNKNOWN in rtl822x_c45_read_status() in case the link
|
|
is down.
|
|
