2007-08-31- cxgb3 engine microcode loadDivy Le Ray
Load the engine microcode when an interface is brought up, instead of of doing it when the module is loaded. Loosen up tight binding between the driver and the engine microcode version. There is no need for microcode update with T3A boards. Fix the file naming. Do a better job at logging the loading activity.

2007-08-31cxgb3 - Fix dev->priv usageDivy Le Ray
cxgb3 used netdev_priv() and dev->priv for different purposes. In 2.6.23, netdev_priv() == dev->priv, cxgb3 needs a fix. This patch is a partial backport of Dave Miller's changes in the net-2.6.24 git branch. Without this fix, cxgb3 crashes on 2.6.23.

2007-07-31[NET]: ethtool_perm_addr only has one implementationMatthew Wilcox
All drivers implement ethtool get_perm_addr the same way -- by calling the generic function. So we can inline the generic function into the caller and avoid going through the drivers. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-07-09RDMA/cxgb3: Streaming -> RDMA mode transition fixesSteve Wise
Due to a HW issue, our current scheme to transition the connection from streaming to rdma mode is broken on the passive side. The firmware and driver now support a new transition scheme for the passive side: - driver posts rdma_init_wr (now including the initial receive seqno) - driver posts last streaming message via TX_DATA message (MPA start response) - uP atomically sends the last streaming message and transitions the tcb to rdma mode. - driver waits for wr_ack indicating the last streaming message was ACKed. NOTE: This change also bumps the required firmware version to 4.3. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-06-03network drivers: eliminate unneeded kill_vid codeStephen Hemminger
Many drivers had code that did kill_vid, but they weren't doing vlan filtering. With new API the stub is unneeded unless device sets NETIF_F_HW_VLAN_FILTER.

2007-04-25[SK_BUFF]: Convert skb->tail to sk_buff_data_tArnaldo Carvalho de Melo
So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

2007-04-25[SK_BUFF]: Introduce skb_transport_header(skb)Arnaldo Carvalho de Melo

For the common, open coded 'skb->h.raw = skb->data' operation, so that we can later turn skb->h.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple cases: skb->h.raw = skb->data; skb->h.raw = {skb_push|[__]skb_pull}() The next ones will handle the slightly more "complex" cases.

2007-03-02[VLAN]: Avoid a 4-order allocation.Dan Aloni
This patch splits the vlan_group struct into a multi-allocated struct.
