+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.
