2008-07-11ixgb: fix race on rx_buffer_len in mtu changeJesse Brandeburg
some random coverage testing found that when changing mtu under heavy traffic load, NAPI would use the rx_buffer_len variable after it had been changed by change_mtu.

2008-07-11via-velocity: move residual free rx descriptors count register updateFrancois Romieu
Updates of the RBRDU have two different meanings depending on their context: 1. the receiving process has not started - the value which is written into the RBRDU register is supposed to be the free rx descriptors count (rounded to a multiple of 4) 2. the receiving process is running - the value increments the count above (sic) The update is currently issued deep inside the rx replenish chain (see velocity_give_many_rx_descs). Let's propagate enough information to the caller so that the rx replenish functions do not depend on hardware any more. It is needed to perform the Rx/Tx buffers housekeeping when MTU changes.

2008-07-11via-velocity: remove the bounce buffersFrancois Romieu
Executive summary: the bounce buffers are in my way - they use something like a 64 * 1500 bytes area of PCI consistent area - they are not resized when the MTU changes - they are used - to hand-pad undersized packets. skb_pad anyone ? - to linearize fragmented skbs whose fragment count goes beyond the 7 fragments hardware limit in order to claim scatter-gather support Actually the SG code is commented out and I wonder if it could not be implemented (ab-)using the large send feature of the chipset since the latter should support some multi-descriptor packet transmitting.

2008-07-08netdev: The ingress_lock member is no longer needed.David S. Miller
Every qdisc is assosciated with a queue, and in the case of ingress qdiscs that will now be netdev->rx_queue so using that queue's lock is the thing to do. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Move queue_lock into struct netdev_queue.David S. Miller
The lock is now an attribute of the device queue. One thing to notice is that "suspicious" places emerge which will need specific training about multiple queue handling. They are so marked with explicit "netdev->rx_queue" and "netdev->tx_queue" references. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-07-08rtl8187: Change detection of RTL8187B with USB ID of 8187Larry Finger
Some early versions of RTL8187B devices have a USB ID of 0x8187 rather than the 0x8189 of later models. In addition, it appears that these early units also must be programmed with lower power. Previous patches used the Product ID string to detect this situation, but did not address the low power question. This patch uses the hardware version and sets the power accordingly.

2008-07-08b43legacy: Remove switch statement with 64-bit indexLarry Finger
The gcc 3.4 fork used to compile the MN10300 port emits unwanted __ucmpdi2() calls for switch statements that use a 64bit value.
