2014-09-203c59x: Fix bad offset spec in skb_frag_dma_mapNeil Horman1-1/+1
Recently aded the use of skb_frag_dma_map to 3c59x, but didn't realize it automatically included the frag_offset internally, as well as provided an option to specify an extra offset in the parameter list. We need to specify an offset of 0 in the parameter list to avoid skb corruption that results in lost connections.

2014-09-203c59x: Add dma error checking and recoveryNeil Horman1-9/+41
Noted that 3c59x has no checks on transmit for failed DMA mappings, and no ability to unmap fragments when a single map fails in the middle of a transmit. This patch provides error checking to ensure that dma mappings work properly, and unrolls an skb mapping if a fragmented skb transmission has a mapping failure to prevent leaks.

2014-09-20net: phy: bcm7xxx: utilize PHY revision in config_initFlorian Fainelli1-6/+15
Now that the GENET and SF2 drivers have been updated to communicate us what is the revision of the BCM7xxx integrated PHY, utilize that information in the config_init() callback to call into the appropriate workaround function based on our revision. While at it, we also print the revision and patch level to help debug new chips. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-20net: dsa: bcm_sf2: communicate integrated PHY revision to PHY driverFlorian Fainelli3-0/+18
The integrated BCM7xxx PHY contains no useful revision information in its MII_PHYSID2 bits 3:0, that information is instead contained in the SWITCH_REG_PHY_REVISION register. Read this register, store its value, and return it by implementing the dsa_switch::get_phy_flags() callback accordingly. The register layout is already matching what the BCM7xxx PHY driver is expecting to find. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-20net: bcmgenet: communicate integrated PHY revision to PHY driverFlorian Fainelli3-2/+14
The integrated BCM7xxx PHY contains no useful revision information in its MII_PHYSID2 bits 3:0, that information is instead contained in the GENET hardware block. We already read the GENET 32-bit revision register, so store the integrated PHY revision in the driver private structure, and then communicate this revision value to the PHY driver by overriding the phy_flags value.

2014-09-19net: fec: Workaround for imx6sx enet tx hang when enable three queuesFugang Duan1-2/+15
When enable three queues on imx6sx enet, and then do tx performance test with iperf tool, after some time running, tx hang. Found that: If uDMA is running, software set TDAR may cause tx hang. If uDMA is in idle, software set TDAR don't cause tx hang. There is a TDAR race condition for mutliQ when the software sets TDAR and the UDMA clears TDAR simultaneously or in a small window (2-4 cycles). This will cause the udma_tx and udma_tx_arbiter state machines to hang. The issue exist at i.MX6SX enet IP. So, the Workaround is checking TDAR status four time, if TDAR cleared by hardware and then write TDAR, otherwise don't set TDAR. The patch is only one Workaround for the issue ERR007885.

In this case, disabling DCB is not an error. We can still function, but we just have to let the user know.

2014-09-18ixgbe: determine vector count inside ixgbe_acquire_msix_vectorsJacob Keller1-37/+37
Our calculated v_budget doesn't matter except if we allocate MSI-X vectors. We shouldn't need to calculate this outside of the function, so don't. Instead, only calculate it once we attempt to acquire MSI-X vectors. This helps collocate all of the MSI-X vector code together.

2014-09-18ixgbe: move msix_entries allocation into ixgbe_acquire_msix_vectorsJacob Keller1-11/+13
We already have to kfree this value if we fail, and this is only part of MSI-X mode, so we should simply allocate the value where we need it. This is cleaner, and makes it a lot more obvious why we are freeing it inside of ixgbe_acquire_msix_vectors.

Similar to how ixgbevf handles acquiring MSI-X vectors, we can return an error code instead of relying on the flag being set.

2014-09-18can: flexcan: put TX mailbox into TX_INACTIVE mode after tx-completeMarc Kleine-Budde1-0/+3
After sending a RTR frame the TX mailbox becomes a RX_EMPTY mailbox. To avoid side effects when the RX-FIFO is full, this patch puts the TX mailbox into TX_INACTIVE mode in the transmission complete interrupt handler. This, of course, leaves a race window between the actual completion of the transmission and the handling of tx-complete interrupt. However this is the best we can do without busy polling the tx complete interrupt. Cc: linux-stable <stable@vger.kernel.org> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
2014-09-18can: flexcan: implement workaround for errata ERR005829David Jander1-1/+15
This patch implements the workaround mentioned in ERR005829: ERR005829: FlexCAN: FlexCAN does not transmit a message that is enabled to be transmitted in a specific moment during the arbitration process. Workaround: The workaround consists of two extra steps after setting up a message for transmission: Step 8: Reserve the first valid mailbox as an inactive mailbox (CODE=0b1000). If RX FIFO is disabled, this mailbox must be message buffer 0. Otherwise, the first valid mailbox can be found using the "RX FIFO filters" table in the FlexCAN chapter of the chip reference manual. Step 9: Write twice INACTIVE code (0b1000) into the first valid mailbox.

2014-09-18can: flexcan: correctly initialize mailboxesDavid Jander1-0/+7
Apparently mailboxes may contain random data at startup, causing some of them being prepared for message reception.
