2014-07-24i40e: Give link more time after setting flow controlCatherine Sullivan1-3/+7
Give link a little more time to come back up after setting flow control before resetting. In the new NVMs it is taking longer for link to come back. This causes the driver to attempt to reset the link, which then errors because the firmware was already in the middle of a reset. Also, initialize err to 0.

2014-07-24i40e/i40evf: fix extension header csum logicJesse Brandeburg2-4/+0
The hardware design requires that the driver avoid indicating checksum offload success on some ipv6 frames with extension headers. The code needs to just check for the IPV6EXADD bit and if it is set punt the checksum to the stack. I don't know why the code was checking TCP on inner protocol, as that code doesn't make any sense to me but seems wrong, so remove it.

2014-07-24i40e/i40evf: Add nvmupdate supportShannon Nelson10-16/+866
This implements a state machine intended to support the userland tool for updating the device eeprom. The state machine implements one-shot reads, writes, multi-step write sessions, and checksum requests. If we're in the middle of a multi-step write session, no one should fire off other writes, however, one shot reads are valid. The userland tool is expected to keep track of its session status, arrange the placement and ordering of the writes, and deal with the checksum requirement. This patch also adds nvmupdate support to ethtool callbacks. The get_eeprom() and set_eeprom() services in ethtool are used here to facilitate the userland NVMUpdate tool. The 'magic' value in the get and set commands is used to pass additional control information for managing the read and write steps. The read operation works both as normally expected in the standard ethtool method, as well as with the extra NVM controls. The write operation works only for the expanded NVM functions - the normal ethtool method is not allowed because of the NVM semaphore management needed for multipart writes, as well as the checksum requirement.

2014-07-24ixgbe: don't check minimum link when direct assigned to virtual machineJacob Keller1-4/+19
This patch prevents the display of the minimum link qualification check if we might be in a virtual machine. This check is incorrect and misleading in this case, since we actually don't really know what the available bandwidth is. To do so, we simply check whether each function on the bus matches our device id. If it doesn't the most likely scenario is that we're directly assigned to a virtual machine.

Add basic support for rx busy polling. Instead of introducing new states and spinlock to synchronize between NAPI and polling method, this patch just reuse NAPI state to avoid extra overhead for fast path and simplified the codes. Test was done between a kvm guest and an external host. Two hosts were connected through 40gb mlx4 cards. With both busy_poll and busy_read are set to 50 in guest, 1 byte netperf tcp_rr shows 127% improvement: transaction rate was increased from 8353.33 to 18966.87.

2014-07-22dp83640: Fix receive timestamp race conditionStefan Sørensen1-71/+102
When timestamping received packets, rx_timestamp_work may be scheduled before the timestamps is received from the hardware resulting in the packet beeing delivered without the timestamp. This is fixed by changing the receive timestamp path: On receiving a packet that need timestamping, the rxts list is traversed. If a match is found, packet+timestamp are delivered, otherwise the packet is added to a rx_queue. When a timestamp arrives rx_queue is traversed and if a matching packet is found, it is delivered with the timestamp. Otherwise the timestamp is added to the rxts list for matching with packets arriving later. In case the hardware drops a timestamp, a workqueue regularly checks the queue for old packets and delivers them without a timestamp.

When port is down dev_addr is changed (e.g. by bonding) but current_mac is not touched. When port is up again, hash_mac is updated to dev_addr, but current_mac isn't. This leads to inconsistency between current_mac and mac_hash. Because of that, mlx4_en_replace_mac() fails to find current_mac in mac_hash.

Now that all the users of mvpp2_bm_bufs_free() have been fixed, we can safely clean the function prototype. The function is always called to release all the buffers in a BM pool, and the number of buffers freed is not needed. Therefore, we change the return to a void, and remove the "num" parameter.

2014-07-22net: mvpp2: Fix the BM pool buffer release checkEzequiel Garcia1-3/+3
After a call to mvpp2_bm_bufs_free(), the caller usually wants to know if the function successfully freed the requested number. However, this cannot be done by looking into the BM pool count, because the current buffer count was updated by mvpp2_bm_bufs_free(). In fact, the current callers of mvpp2_bm_bufs_free() use it to release all the buffers in the pool, so we can fix this by simply checking if the pool is not empty.

2014-07-22net: mvpp2: Enable proper PHY polling and fix port functionalityMarcin Wojtas1-8/+32
Currently, the network interfaces that are not configured by the bootloader (using e.g. tftp or ping) can detect the link status but are unable to transmit data. The network controller has a functionality that allows the hardware to continuously poll the PHY and directly update the MAC configuration accordingly (speed, duplex, etc.). However, this doesn't work well with phylib's software-based polling and updating MAC configuration in the driver's callback. This commit fixes this issue by: 1. Setting MVPP2_PHY_AN_STOP_SMI0_MASK in MVPP2_PHY_AN_CFG0_REG in mvpp2_init(), which disables the harware polling feature. 2. Disabling MVPP2_GMAC_PCS_ENABLE_MASK bit in MVPP2_GMAC_CTRL_2_REG in mvpp2_port_mii_set() for port types other than SGMII. Signed-off-by: Marcin Wojtas <mw@semihalf.com> Signed-off-by: David S.
