These drivers already call netif_stop_queue() so we should not be called unless tx space is available. Just free the skb and return TX_OK. Followup patch will remove NETDEV_TX_LOCKED from the kernel.

similar to atl1c: lock is only used in ndo_start_xmit, but we also advertised LLTX, so remove that as well and let core stack handle tx locking. Allows to remove the TX_LOCKED return value from the driver. Cc: Jay Cliburn <jcliburn@gmail.com> Cc: Chris Snook <chris.snook@gmail.com> Signed-off-by:

AFAICS this is safe: the lock is only used in the .ndo_start_xmit function and this driver does not set LLTX. Gets rid of TX_LOCKED return value, followup patches will remove it. Cc: Jay Cliburn <jcliburn@gmail.com> Cc: Chris Snook <chris.snook@gmail.com> Signed-off-by:

ndo_start_xmit never returns it to stack, but nes_nic_send helper used it if skb could not be queued to hardware. Switch to bool instead. Cc: <linux-rdma@vger.kernel.org> Signed-off-by:

Sergei Shtylyov says: ==================== Don't return NULL from get_phy_device() anymore Here's the set of 5 patches against DaveM's 'net-next.git' repo. The first patch makes get_phy_device() return only error values on error, the rest of the patches clean up the callers of that function... ==================== Signed-off-by: -

Arnd Bergmann asked that get_phy_device() returns either NULL or the error value, not both on error. Do as he said, return ERR_PTR(-ENODEV) instead of NULL when the PHY ID registers read as all ones. Suggested-by:

For sctp assoc, when rcvbuf_policy is set, it will has it's own rmem_alloc, when we dump asoc info in sctp_diag, we should use that value on RMEM_ALLOC as well, just like WMEM_ALLOC. Signed-off-by:

macvtap_device_event(NETDEV_UNREGISTER) should check vlan->minor to determine if it is being invoked in the context of a macvtap_newlink that failed, for example in this code sequence: macvtap_newlink macvlan_common_newlink register_netdevice call_netdevice_notifiers(NETDEV_REGISTER, dev) macvtap_device_event(NETDEV_REGISTER) <fail here, vlan->minor = 0> rollback_registered(dev); rollback_registered_many call_netdevice_notifiers(NETDEV_UNREGISTER, dev); macvtap_device_event(NETDEV_UNREGISTER) <nothing to clean up here> Signed-off-by:Francesco Ruggeri <fruggeri@arista.com> Acked-by:

If macvlan_common_newlink fails in register_netdevice after macvlan_init then it decrements port->count twice, first in macvlan_uninit (from register_netdevice or rollback_registered) and then again in macvlan_common_newlink. A similar problem may exist in the ipvlan driver. This patch consolidates modifications to port->count into macvlan_init and macvlan_uninit (thanks to Eric Biederman for suggesting this approach). v3: remove macvtap specific bits. Signed-off-by:

Manish Chopra says: ==================== qed: Bandwidth configuration support This series adds support in driver for min/max bandwidth configuration for the PF on the link change notification or on explicit request of bandwidth update from the MFW [management firmware].

This patch adds relevant APIs needed to configure WFQ (Weighted fair queueing) values for the vports. WFQ configuration is used per vport basis when minimum bandwidth update/configuration is notified to the PF by the management firmware. Signed-off-by:

Hariprasad Shenai says: ==================== cxgb4: minor fixes, decode msgs and code refactor for few functions This patch series adds new routine to get adapter information and removes some redundant messages logged in dmesg. Fixes race while freeing tx descriptors. Decodes module type and link down reason codes obtained from firmware. Refactor port initialization and FW_PORT_CMD handling. Pass correct port id in DCB message handler to obtain netdev associated. This patch series has been created against net-next tree and includes patches on cxgb4 driver. We have included all the maintainers of respective drivers. Kindly review the change and let us know in case of any review comments. ==================== Signed-off-by: -

The firmware can send a set of asynchronous replies through FW_PORT_CMD with DCBX information when that's negotiated with the Link Peer. The old code always assumed that a FW_PORT_CMD reply was always a Get Port Information message. This change conditionalizes the code to only handle the Get Port Information messages and throws a warning if we don't understand what we've been given. Also refactor t4_handle_fw_rpl() so that core functionality performed by t4_handle_get_port_info() for a specified port. Signed-off-by:

There could be race between t4_eth_xmit() and t4_free_sge_resources() while freeing tx descriptors, take txq lock in t4_free_sge_resources(). We need to stop the xmit frame path which runs in bottom half context while unloading the driver using _bh variant of the lock. This is to prevent the deadlock between xmit and driver unload.

Nicolas Dichtel says: ==================== netlink: align attributes when needed (patchset #3) This is the continuation (series #3) of the work done to align netlink attributes when these attributes contain some 64-bit fields. It's the last patchset from what I've seen. The last user of nla_put_u64() is block/drbd. This module does not use standard netlink API (see all the stuff in include/linux/genl_magic_struct.h and include/linux/genl_magic_func.h). I didn't modify it because it's seems hard to do it whithout testing and fully understanding the context (for example, why include/linux/drbd_genl.h is not part of uapi?). Any thoughts? ==================== Signed-off-by: -

Tom Herbert says: ==================== ila: Support for checksum neutral translations This patch set updates ILA to support draft-herbert-nvo3-ila-02. The primary addition is support checksum neutral ILA translation. This allows address to be performed and still keep any transport layer checksums that include the addresses in their pseudo header to still be correct without the translator needing to parse L4. Other items are: - Structures for ILA addresses, identifiers, locators - Disallow translation on non-ILA addresses (check by type in identifier). - Change xlat (nf_input) to translates solely based on matching locators not identifiers (since identifiers are not obfuscated by checksum neutral). - Side effect if above is that multiple ILA domains are supported. Each local locator can map to a different SIR address (ILA domain), and each domain defines its own identifier space. Tested: Ran TCP_RR with 200 cnxs. ILA performance is slightly better than previously since we are not longer parsing L4 for checksum handling. I amd seeing about 1% performance overhead. Also ran TCP_STREAM and tested non-ILA address (type=0) are not translated. v2: Fix compilation errors ==================== Signed-off-by: -

Support checksum neutral ILA as described in the ILA draft. The low order 16 bits of the identifier are used to contain the checksum adjustment value. The csum-mode parameter is added to described checksum processing. There are three values: - adjust transport checksum (previous behavior) - do checksum neutral mapping - do nothing On output the csum-mode in the ila_params is checked and acted on. If mode is checksum neutral mapping then to mapping and set C-bit. On input, C-bit is checked. If it is set checksum-netural mapping is done (regardless of csum-mode in ila params) and C-bit will be cleared. If it is not set then action in csum-mode is taken. Signed-off-by:

Change model of xlat to be used only for input where lookup is done on the locator part of an address (comparing to locator_match as key in rhashtable). This is needed for checksum neutral translation which obfuscates the low order 16 bits of the identifier. It also permits hosts to be in muliple ILA domains (each locator can map to a different SIR address). A check is also added to disallow translating non-ILA addresses (check of type in identifier).
