[1/14] Orinoco driver updates - use netif_carrier_*()

[11/14] Orinoco driver updates - delay Tx wake

2005-02-23 Thread David Gibson
Delay netif_wake_queue() until the packet has actually been transmitted, rather than just when the firmware has copied it into its internal buffers. This seems to prevent problems on some Intersil firmware versions (I suspect the problems were caused by the firmware's buffers filling up).
