2008-03-25libertas: remove some unused commandsHolger Schurig
Neither CMD_802_11_PAIRWISE_TSC nor CMD_802_11_GROUP_TSC is used or documented. It might have something to do with TKIP sequence counters, but that's just an educated guess. Remove all occurences of them. CMD_CODE_DNLD is also neither used nor documented.

2008-03-25libertas: rename packetfilter to mac_controlHolger Schurig
The CMD_MAC_CONTROL can be used for other things than just filtering packets, e.g. to enable and disable WMM. This uses the same term mac_control for the define, the function and the shadow value in struct lbs_private.

2008-03-17forcedeth: limit tx to 16Ayaz Abdulla
This is a critical patch which adds a workaround for a HW bug. The patch will limit the number of outstanding tx packets to 16. Otherwise, the HW could send out packets with bad checksums. The driver will still setup the tx packets into the ring, however, will only set the Valid bit on 16 packets at a time.

2008-03-17cxgb3: Fix transmit queue stop mechanismDivy Le Ray
The last change in the Tx queue stop mechanism opens a window where the Tx queue might be stopped after pending credits returned. Tx credits are returned via a control message generated by the HW. It returns tx credits on demand, triggered by a completion bit set in selective transmit packet headers. The current code can lead to the Tx queue stopped with all pending credits returned, and the current frame not triggering a credit return. The Tx queue will then never be awaken. The driver could alternatively request a completion for packets that stop the queue. It's however safer at this point to go back to the pre-existing behaviour.

This patch should resolve a problem that's troubled support for some RNDIS peripherals.

2008-03-17NEWEMAC: fix support for pause packetsPravin M. Bathija
Problem Description and Fix --------------------------- When a pause packet(with destination as reserved Multicast address) is received by the EMAC hardware to control the flow of frames being transmitted by it, it is dropped by the hardware unless the reserved Multicast address is hashed in to the GAHT[1-4] registers. This code fix adds the default reserved multicast address to the GAHT[1-4] registers in the EMAC(s) present on the chip. The flow control with Pause packets will only work if the following register bits are programmed in EMAC: EMACx_MR1[APP] = 1 EMACx_RMR[BAE] = 1 EMACx_RMR[MAE] = 1 Behavior that may be observed in a running system ------------------------------------------------- A host transferring data from a PPC based system may send a Pause packet to the PPC EMAC requesting it to slow down the flow of packets. If the default reserved multicast MAC address is not programmed into the GAHT[1-4] registers this Pause packet will be dropped by PPC EMAC and no Flow Control will be done. Signed-off-by: Pravin M.

V . interrupt is delivered . skb_recv_done does atomic napi test, ok some waiting disable_cb is called->check fails->bang! . poll would do napi check poll would do disable_cb The fix is to let enable_cb not disable the interrupt again, but expect the caller to do the cleanup if it returns false. In that case, the interrupt is only disabled, if the napi test_set_bit was successful.

2008-03-17ixgbe: Introduce adaptive interrupt moderationAyyappan Veeraiyan
82598 can produce a formidable interrupt rate, and is largely unusable without some form of moderation. The default behaviour before this patch is to limit irq's to a reasonable number. However, just like our other drivers we can reduce latency for small packet-type traffic considerably by allowing the irq rate to go up dynamically. This patch introduces a simple irq moderation algorithm based on traffic analysis. The driver will use more CPU to service small packets quicker but will perform the same on bulk traffic as the old code.
