2014-07-23virtio-net: rx busy polling supportJason Wang1-1/+47
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.

2014-07-22net/mlx4_en: current_mac isn't updated in port upEyal Perry1-0/+1
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. Fix is to reset current_mac to dev_addr when port is up - as we do for mac_hash. Signed-off-by: Eyal Perry <[email protected]> Signed-off-by: Amir Vadai <[email protected]> Signed-off-by: David S.

2014-07-22net: mvpp2: Simplify BM pool buffers freeingEzequiel Garcia1-13/+6
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. This is a cosmetic change, to make the code slightly cleaner. Signed-off-by: Ezequiel Garcia <[email protected]> Signed-off-by: David S. Miller <[email protected]>
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 <[email protected]> Signed-off-by: David S.
