Subject: [PATCH] enetc: update TSN Qbv PSPEED set according to adjust link
|
|
speed
|
|
|
|
ENETC has a register PSPEED to indicate the link speed of hardware.
|
|
It is need to update accordingly. PSPEED field needs to be updated
|
|
with the port speed for QBV scheduling purposes. Or else there is
|
|
chance for gate slot not free by frame taking the MAC if PSPEED and
|
|
phy speed not match. So update PSPEED when link adjust. This is
|
|
implement by the adjust_link.
