From ea177305b321a4127e448b88de20d5792682ace1 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Mon, 2 Jun 2008 17:51:23 -0400 Subject: ipw2200: queue direct scans When another scan is in progress, a direct scan gets dropped on the floor. However, that direct scan is usually the scan that's really needed by userspace, and gets stomped on by all the broadcast scans the ipw2200 driver issues internally. Make sure the direct scan happens eventually, and as a bonus ensure that the passive scan worker is cleaned up when appropriate. The change of request_passive_scan form a struct work to struct delayed_work is only to make the set_wx_scan() code a bit simpler, it's still only used with a delay of 0 to match previous behavior.

When we get a "PS sleep" event, we have to confirm this to the firmware. The confirm happens with a command, but this command is special: the firmware won't send us a response. if_cs_host_to_card() is setting priv->dnld_sent anyway, so this variable stayed at DNLD_DATA_SENT and was never cleared back. Now I put the special knowledge that the CMD_802_11_PS_MODE with CMD_SUBCMD_SLEEP_CONFIRMED doesn't need to need a response by directly clearing the dnld_sent state in lbs_send_confirmsleep().

The problem is that the added flow control check will always fail if flow control is set to autoneg and either RX or TX (or both) flow control is enabled. The driver defaults to setting flow control to autoneg and advertises both RX and TX flow control. The fix is to remove the errant check.

The first problem is that GPIO 0 and GPIO 2 have been swapped. This change prevented the administrator from turning on WOL when it is disabled in NVRAM. The fix is to add a new path for the 5761 that swaps the two GPIOs in the code as well. The second problem is that GPIO 1 could not be toggled by the driver because the GPIO is shared with the debug UART GPIO. This will prevent the administrator from being able to turn WOL off if it was enabled in NVRAM. The fix is to always disable the debug UART after a GRC reset.

If the queue is full, it then enables interrupts and waits for notification that more work has been performed. However, a side-effect of this scheme is that there are always xmit skbs left dangling when no new packets are sent, against the Documentation/networking/driver.txt guideline: "... it is not allowed for your TX mitigation scheme to let TX packets "hang out" in the TX ring unreclaimed forever if no new TX packets are sent." Add a timer to ensure that any time we queue new TX skbs, we will shortly free them again. This fixes an easily reproduced hang at shutdown where iptables attempts to unload nf_conntrack and nf_conntrack waits for an skb it is tracking to be freed, but virtio_net never frees it.
