[BRIDGE]: Kill clone argument to br_flood_*

2007-09-16T23:20:48Z

The clone argument is only used by one caller and that caller can clone the packet itself. This patch moves the clone call into the caller and kills the clone argument. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[NET]: Share correct feature code between bridging and bonding

2007-08-14T05:52:14Z

http://bugzilla.kernel.org/show_bug.cgi?id=8797 shows that the bonding driver may produce bogus combinations of the checksum flags and SG/TSO. For example, if you bond devices with NETIF_F_HW_CSUM and NETIF_F_IP_CSUM you'll end up with a bonding device that has neither flag set. If both have TSO then this produces an illegal combination. The bridge device on the other hand has the correct code to deal with this. In fact, the same code can be used for both. So this patch moves that logic into net/core/dev.c and uses it for both bonding and bridging. In the process I've made small adjustments such as only setting GSO_ROBUST if at least one constituent device supports it. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

bridge: allow changing hardware address to any valid address

2007-04-26T05:28:50Z

For case of bridging pseudo devices, the get created/destroyed (Xen) need to allow setting address to any valid value. Signed-off-by: Stephen Hemminger

[SK_BUFF]: Introduce skb_reset_mac_header(skb)

2007-04-26T05:24:32Z

For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can later turn skb->mac.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 case, next will handle the slightly more "complex" cases. Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[NET]: Added GSO header verification

2006-06-29T23:57:53Z

When GSO packets come from an untrusted source (e.g., a Xen guest domain), we need to verify the header integrity before passing it to the hardware. Since the first step in GSO is to verify the header, we can reuse that code by adding a new bit to gso_type: SKB_GSO_DODGY. Packets with this bit set can only be fed directly to devices with the corresponding bit NETIF_F_GSO_ROBUST. If the device doesn't have that bit, then the skb is fed to the GSO engine which will allow the packet to be sent to the hardware if it passes the header check. This patch changes the sg flag to a full features flag. The same method can be used to implement TSO ECN support. We simply have to mark packets with CWR set with SKB_GSO_ECN so that only hardware with a corresponding NETIF_F_TSO_ECN can accept them. The GSO engine can either fully segment the packet, or segment the first MTU and pass the rest to the hardware for further segmentation. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[BRIDGE]: Add support for NETIF_F_HW_CSUM devices

2006-06-18T05:06:45Z

As it is the bridge will only ever declare NETIF_F_IP_CSUM even if all its constituent devices support NETIF_F_HW_CSUM. This patch fixes this by supporting the first one out of NETIF_F_NO_CSUM, NETIF_F_HW_CSUM, and NETIF_F_IP_CSUM that is supported by all constituent devices.

[BRIDGE]: forwarding remove unneeded preempt and bh diasables

2006-03-21T06:58:36Z

Optimize the forwarding and transmit paths. Both places are called with bottom half/no preempt so there is no need to use spin_lock_bh or rcu_read_lock. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

[BRIDGE]: limited ethtool support

2006-01-03T21:11:03Z

Add limited ethtool support to bridge to allow disabling features. Note: if underlying device does not support a feature (like checksum offload), then the bridge device won't inherit it. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller
