From 97b33bdf9bddb6bebc2e87148df3e30aa7a13b2d Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Thu, 30 May 2019 15:11:06 +0200 Subject: [PATCH] net: phy: export phy_queue_state_machine We face the issue that link change interrupt and link status may be reported by different PHY layers. As a result the link change interrupt may occur before the link status changes. Export phy_queue_state_machine to allow PHY drivers to specify a delay between link status change interrupt and link status check. v2: - change jiffies parameter type to unsigned long Signed-off-by: Heiner Kallweit Suggested-by: Russell King Acked-by: Russell King Signed-off-by: David S.
