Subject: [PATCH 1/1] net: dsa: mt7530: add support for in-band link status
|
|
|
|
Read link status from SGMII PCS for in-band managed 2500Base-X and
|
|
1000Base-X connection on a MAC port of the MT7531. This is needed to
|
|
get the SFP cage working which is connected to SGMII interface of
|
|
port 5 of the MT7531 switch IC on the Bananapi BPi-R3 board.
|
|
While at it also handle an_complete for both the autoneg and the
|
|
non-autoneg codepath.
