When processing the unregister notify for a hard interface, removing the sysfs files may lead to a circular deadlock (rtnl mutex <-> s_active). To overcome this problem, postpone the sysfs removal in a worker. Reported-by:

A delayed_work struct does not need to be initialized each every time before being enqueued. Therefore the INIT_DELAYED_WORK() macro should be used during the initialization process only. Signed-off-by:

The rmb in the Tx cleanup path is a much stronger barrier than we really need. All that is really needed is a read_barrier_depends since the location of the EOP descriptor is dependent on the eop_desc value. Signed-off-by:

When the physical function (PF) is reset for any reason the statistics collection in ixgbevf_update_stats needs to wait to update until after the reset synchronization ensures that the PF driver is up and running and is finished with its own reset. Go ahead and clear the link flag to indicate this when the control message from the PF is received. The reset synchronization and recovery in the watchdog task will eventually set the link flag up when the PF has resumed. Signed-off-by:

The out of tree driver and the in kernel driver should use the same interrupt handling logic for mailbox interrupts. The difference in the handlers was causing dissimilar behavior between the two drivers complicating debug and trouble shooting. Signed-off-by:

This change is meant to both improve the performance and reduce the size of ixgbe_tx_map. To do this I have expanded the work done in the main loop by pushing first into tx_buffer. This allows us to pull in the dma_mapping_error check, the tx_buffer value assignment, and the initial DMA value assignment to the Tx descriptor. The net result is that the function reduces in size by a little over a 100 bytes and is about 1% or 2% faster. Signed-off-by:

This change is meant to improve the efficiency of the Tx flags in ixgbe by aligning them with the values that will later be written into either the cmd_type or olinfo. By doing this we are able to reduce most of these functions to either just a simple shift followed by an or in the case of cmd_type, or an and followed by an or in the case of olinfo. To do this I also needed to change the logic and/or drop some flags. I dropped the IXGBE_TX_FLAGS_FSO and it was replaced by IXGBE_TX_FLAGS_TSO since the only place it was ever checked was in conjunction with IXGBE_TX_FLAGS_TSO. I replaced IXGBE_TX_FLAGS_TXSW with IXGBE_TX_FLAGS_CC, this way we have a clear point for what the flag is meant to do. Finally the IXGBE_TX_FLAGS_NO_IFCS was dropped since were are already carrying the data for that flag in the skb. Instead we can just check the bitflag in the skb. In order to avoid type conversion errors I also adjusted the locations where we were switching between CPU and little endian. Signed-off-by:

We were spending cycles separating the FCoE and TSO contexts even though we always overwriting the context anyway. Instead of doing that we can just use context 0 for all descriptors. Signed-off-by:

This change is meant to reduce the overhead for workloads that are not using either TSO or checksum offloads. Most of the time the compiler should jump ahead after failing this check to the VLAN check since in the ixgbe_tx_csum call we start with that check as well. Signed-off-by:

IEEE DCBx has a mechanism to change the default user priority. In the normal case the OS can handle this via cgroups, iptables, socket, options etc. With SR-IOV and direct assigned VF devices the default priority needs to be set by the PF device so the inserted VLAN tag is correct. Signed-off-by:

These are copying data into 16 char arrays. They all specify that the first string can't be more than 11 characters but once you add on the "-rx-" and the NUL character there isn't space for the %d. The first string is probably never going to be 11 characters, but if it is then let's truncate the string instead of corrupting memory. Signed-off-by:

When there is heavy transmission traffic in the CPDMA, then Rx descriptors memory is also utilized as tx desc memory looses all rx descriptors and the driver stops working then. This patch adds boundary for tx and rx descriptors in bd ram dividing the descriptor memory to ensure that during heavy transmission tx doesn't use rx descriptors. This patch is already applied to davinci_emac driver, since CPSW and davici_dmac shares the same CPDMA, moving the boundry seperation from Davinci EMAC driver to CPDMA driver which was done in the following commit commit 86d8c07f Author: Sascha Hauer <s.hauer@pengutronix.de> Date: Tue Jan 3 05:27:47 2012 +0000 net/davinci: do not use all descriptors for tx packets The driver uses a shared pool for both rx and tx descriptors. During open it queues fixed number of 128 descriptors for receive packets. For each received packet it tries to queue another descriptor. If this fails the descriptor is lost for rx. The driver has no limitation on tx descriptors to use, so it can happen during a nmap / ping -f attack that the driver allocates all descriptors for tx and looses all rx descriptors. The driver stops working then. To fix this limit the number of tx descriptors used to half of the descriptors available, the rx path uses the other half. Tested on a custom board using nmap / ping -f to the board from two different hosts. Signed-off-by:
