Don adds additional support for X550 MAC types, which require additional steps around enabling and disabling Rx. Also cleans up variable type inconsistency. I provide a patch to allow relaxed ordering to be enabled on SPARC architectures. Also cleans up ixgbevf whitespace and code comments to align the driver with networking coding standard.

2015-03-14at86rf230: add support for calibration timeoutAlexander Aring
This patch adds a handling for calibration if we are 5 minutes in PLL state. I first tried to implement the calibration functionality in TX_ON state via register values CF_START and DCU_START, but this occurs a one second delay at each calibration time. An another solution to start a calibration is to switch from TRX_OFF state into TX_ON, then a calibration is done automatically by transceiver. This method will be used in this patch, after each transmit of a frame we check with jiffies if the PLL is set 5 minutes without doing a TRX_OFF->(TX_ON || RX_AACK_ON) or channel switch. The worst case would be a transceiver in receiving mode only, but this is under normal operation very unlikely.

Delay the update of the TDMA producer index unless this is the last SKB in a batch, or the queue is already stopped.

There is no need to have both bcmgenet_xmit_single() and bcmgenet_xmit_frag() perform a free_bds decrement and a prod_index increment by one. In case one of these functions fails to map a SKB or fragment for transmit, we will return and exit bcmgenet_xmit() with an error. We can therefore safely use our local copy of nr_frags to know by how much we should decrement the number of free buffers available, and by how much the producer count must be incremented and do this in the tail of bcmgenet_xmit().

2015-03-13net: bcmgenet: rewrite bcmgenet_rx_refill()Petri Gynther
Currently, bcmgenet_desc_rx() calls bcmgenet_rx_refill() at the end of Rx packet processing loop, after the current Rx packet has already been passed to napi_gro_receive(). However, bcmgenet_rx_refill() might fail to allocate a new Rx skb, thus leaving a hole on the Rx queue where no valid Rx buffer exists. To eliminate this situation: 1. Rewrite bcmgenet_rx_refill() to retain the current Rx skb on the Rx queue if a new replacement Rx skb can't be allocated and DMA-mapped. In this case, the data on the current Rx skb is effectively dropped. 2. Modify bcmgenet_desc_rx() to call bcmgenet_rx_refill() at the top of Rx packet processing loop, so that the new replacement Rx skb is already in place before the current Rx skb is processed.

2015-03-13net/macb: Only adjust tx_clk on link changeJaeden Amero
The PHY state machine (in drivers/net/phy/phy.c) will unconditionally call phydev->adjust_link (macb_handle_link_change) when polling in the PHY_CHANGELINK state. As currently written, macb always ends up requesting a new tx_clk frequency in macb_handle_link_change. It is a waste of time to request a new tx_clk frequency if the link state hasn't changed, as the tx_clk will already be configured properly. Let's only request a new tx_clk clock frequency when necessary.

2015-03-09can: kvaser_usb: Read all messages in a bulk-in URB bufferAhmed S. Darwish
The Kvaser firmware can only read and write messages that are not crossing the USB endpoint's wMaxPacketSize boundary. While receiving commands from the CAN device, if the next command in the same URB buffer crossed that max packet size boundary, the firmware puts a zero-length placeholder command in its place then moves the real command to the next boundary mark. The driver did not recognize such behavior, leading to missing a good number of rx events during a heavy rx load session. Moreover, a tx URB context only gets freed upon receiving its respective tx ACK event. Over time, the free tx URB contexts pool gets depleted due to the missing ACK events. Consequently, the netif transmission queue gets __permanently__ stopped; no frames could be sent again except after restarting the CAN newtwork interface. Signed-off-by: Ahmed S.

Most notably, Greg provides the patch to remove the dreaded configfs changes in the driver. Shannon cleans up a sparse warning by simply straighting out the code so it is less convoluted. Fixes an issue where the vector allocation was trying too hard to save vectors for VMDq, to the point of not giving the PF enough when in a tight situation, such as an NPAR partition. Changed the driver to make sure that the PF will get all the queues and vectors it wants to fill out its destiny. Cleans up reporting to only print the port and VEB stats if it is the first partition of a multiplexed port. Catherine cleans up some duplicated code by simply removing the duplicate code. Kamil cleans up the driver by removing an un-needed endian conversion because it is already done by a register read function. Jesse fixes a variable width of a datatype, where a u16 should have been a u32. Also cleans up debug_read_register() to resolve some sparse warnings. Updates the driver to use prefetch() to get the next Tx descriptor, like in ixgbe, to improve performance. Akeem moves around code to enable/disable loopback so that other non-SRIOV supported driver functions can take advantage of the changes. Anjali cleans up the logging for adding/deleting FD-SB filters, since ethtool shows all the filters on an interface. Updates the driver to use l4_tunnel type generically to keep code flow simple. Simplifies the RSS code since the driver initializes the rss_size_max in sw_init. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
