Subject: [PATCH] net: phylink: call mac_an_restart for SGMII/QSGMII inband
|
||
|
|
interfaces too
|
||
|
|
|
||
|
|
It doesn't quite make sense why restarting the AN process should be
|
||
|
|
unique to 802.3z (1000Base-X) modes. It is valid to put an SGMII PCS in
|
||
|
|
in-band AN mode, therefore also make PHYLINK re-trigger an
|
||
|
|
auto-negotiation if needed.
|
