From d9e2d185bf01e20339158f77c3fca00b02014912 Mon Sep 17 00:00:00 2001 From: Mark Lord Date: Wed, 30 Nov 2005 22:30:23 +0100 Subject: b44: missing netif_wake_queue() in b44_open() This patch fixes a problem plaguing Dell notebooks with built-in b44 ethernet: The driver refuses to transmit packets of any kind until after the first 5-second tx_timeout occurs. This bug causes DHCP negotiation to fail (timeout) during installation of Ubuntu Linux.

Currently, when we stop TX/RX channels we just do some number of loops without relying on actual spent time. This has finally bitten me on one of our systems (heavy network traffic during start up, RX channel is stopped several times to configure multicast list). Graceful channel stop can take up to 1 frame time, so I've added device specific timeout counter which depends on current link speed and calls to udelay() to really wait required amount of time before giving up.
