2008-03-25libertas: store rssi as an u32Holger Schurig
Don't store an (hardware base) u8 value in bss_descriptor, but just an unsigned int (RSSI is really unsigned). Compilers generate more efficent code for ints than for bytes.

2008-03-25libertas: convert GET_LOG to a direct commandHolger Schurig
Now uses __lbs_cmd() to get the "log" (it's actually more a snapshot of various counters, not a sequential log). Besides the "mechanical" convertion the patch add the following logical changes: * Removes the priv->logmsg variable, it was only used in one place anyway, also don't blindly get the counters when associating. Getting the counters then the user asks via WEXT for them is good enought. * don't set wstats.discard.fragment with log.rxfrag, because the latter is a counter for successfully received packets, not for fragmented packets.

2008-03-25libertas: fix scheduling while atomic bug in CMD_MAC_CONTROLHolger Schurig
The old code incorrectly used lbs_cmd_with_response() and now uses lbs_cmd_async(). While there I noticed that there is no real useful return values for asynchronous command functions, so I made the function "void".

2008-03-25libertas: make a handy lbs_cmd_async() commandHolger Schurig
This uses a static lbs_cmd_async_callback function, which is a noop. Just setting the callback argument to __lbs_cmd_async() to NULL won't work, because then the cmdnode wouldn't be released. This also makes __lbs_cmd_async() a static method, which is now only used by lbs_cmd() and lbs_cmd_async().

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.

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.

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.

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.
