The patch roll back the change we made to support for the ability to start/stop independent Tx queues within a single net device in order to support 802.11e QoS. We need to be able to indicate to the upper layers that packets of a given priority can not be sent any more without halting transmission of all packets, and without rescheduling high priority packets down to the next priority level. So we return NETDEV_TX_BUSY in this case and rely on the stack would take care of rescheduling... which it apparently does immediately and consumes the CPU. This caused the ksoftirqd kernel thread consuming almost all the CPU... To put the code back to the way it was before we made these changes we put the call netif_queue_stop back in ipw_tx_skb. This effectively disables multiple priority based transmit queues for 802.11e, but given that its broken anyway...

README ------ This directory is mostly for Wireless LAN drivers, in their various incarnations (ISA, PCI, Pcmcia...). This separate directory is needed because a lot of driver work on different bus (typically PCI + Pcmcia) and share 95% of the code. This allow the code and the config options to be in one single place instead of scattered all over the driver tree, which is never 100% satisfactory. Note : if you want more info on the topic of Wireless LANs, you are kindly invited to have a look at the Wireless Howto : http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/ Some Wireless LAN drivers, like orinoco_cs, require the use of Wireless Tools to be configured : http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html Special notes for distribution maintainers : 1) wvlan_cs will be discontinued soon in favor of orinoco_cs 2) Please add Wireless Tools support in your scripts Have fun...
