Don't provide FCoE and iSCSI statistics to management firmware if CONFIG_CNIC is not set. Some needed structure fields are not defined without CONFIG_CNIC.

This patch moves the sock_ code from inet_diag.c to generic sock_diag.c file and provides necessary request_module-s calls and a pointer on inet_diag_compat dumping routine. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Now all the code works with sock_diag_req-compatible structs, so it's possible to stop using the inet_diag_type2proto in inet_csk_diag_fill. Pass the inet_diag_req into it and use the sdiag_protocol field. At the same time remove the explicit ext argument, since it's also on the req. However, this conversion is still required in _compat code, so just move this routine, not remove. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S.

The new API will specify family to work with. Teach the existing socket walking code to bypass not interesting ones. To preserve compatibility with existing behavior the _compat code sets interesting family to AF_UNSPEC to dump them all. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S.

Make inet_diag_dumo work with given header instead of calculating one from the nl message. The SOCK_DIAG_BY_FAMILY just passes skb's one through, the compat code converts the old header to new one. Also fix the bytecode calculation to find one at proper offset. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This one coinsides with the sock_diag_req in the beginning and contains only used fields from its previous analogue. The existing code is patched to use the _compat version of it for now. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>

When receiving the SOCK_DIAG_BY_FAMILY message we have to find the handler for provided family and pass the nl message to it. This patch describes an infrastructure to work with such nandlers and implements stubs for AF_INET(6) ones. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S.

Sorry, but the vger didn't let this message go to the list. Re-sending it with less spam-filter-prone subject. When dumping the AF_INET/AF_INET6 sockets user will also specify the protocol, so prepare the protocol diag handlers to work with IPPROTO_ constants.

The ultimate goal is to get the sock_diag module, that works in family+protocol terms. Currently this is suitable to do on the inet_diag basis, so rename parts of the code. It will be moved to sock_diag.c later. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>

commit 2df1a70a "bnx2x: Support for byte queue limits" has introduced an asymmetry in usage of netdev_tx_completed_queue and netdev_tx_sent_queue. Missing call to netdev_tx_sent_queue causes the crash during ethtool -t. The patch adds the missing call.

This patch adds functionality for avoiding orphaning SKB too early. The original skb is stashed away and the original destructor is called from the hi-jacked flow-on callback. If CAIF interface goes down and a hi-jacked SKB exists, the original skb->destructor is restored. Signed-off-by: Sjur Brændeland <sjur.brandeland@stericsson.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Flow control is implemented by inspecting the qdisc queue length in order to detect potential overflow on the TX queue. When a threshold is reached flow-off is sent upwards in the CAIF stack. At the same time the skb->destructor is hi-jacked by orphaning the SKB and the original destructor is replaced with a "flow-on" callback. When the "hi-jacked" SKB is consumed the queue should be empty, and the "flow-on" callback is called and xon is sent upwards in the CAIF stack.

NCM 1.0 does not support anything but Ethernet framing, hence CAIF payload will be put into Ethernet frames. Discovery is based on fixed USB vendor 0x04cc (ST-Ericsson), product-id 0x230f (NCM). In this variant only CAIF payload is sent over the NCM interface. The CAIF stack (cfusbl.c) will when USB interface register first check if we got a CDC NCM USB interface with the right VID, PID. It will then read the device's Ethernet address and create a 'template' Ethernet TX header, using a broadcast address as the destination address, and EthType 0x88b5 (802.1 Local Experimental - vendor specific). A protocol handler for 0x88b5 is setup for reception of CAIF frames from the CDC NCM USB interface. Signed-off-by: Sjur Brændeland <sjur.brandeland@stericsson.com> Signed-off-by: David S.

Reduce the number of dst_get_neighbour_noref() calls within a single call chain. Primarily by passing the neighbour pointer down to the helper functions. Handle dst_get_neighbour_noref() returning NULL in ipoib_start_xmit() by incrementing the dropped counter and freeing the packet. We don't want it to fall through into the ARP/RARP/multicast handling, since that should only happen when skb_dst() is NULL. Signed-off-by: David S.

IPV4 should do exactly what the IPV6 code does here, which is use the neighbour obtained via the dst entry.
