2011-02-17enic: Bug fix: Reset driver count of registered unicast addresses to zero ↵Vasanthy Kolluri
during device reset During a device reset, clear the counter for the no. of unicast addresses registered. Also, rename the routines that update unicast and multicast address lists.

2011-02-15sfc: Add TX queues for high-priority trafficBen Hutchings
Implement the ndo_setup_tc() operation with 2 traffic classes. Current Solarstorm controllers do not implement TX queue priority, but they do allow queues to be 'paced' with an enforced delay between packets. Paced and unpaced queues are scheduled in round-robin within two separate hardware bins (paced queues with a large delay may be placed into a third bin temporarily, but we won't use that). If there are queues in both bins, the TX scheduler will alternate between them. If we make high-priority queues unpaced and best-effort queues paced, and high-priority queues are mostly empty, a single high-priority queue can then instantly take 50% of the packet rate regardless of how many of the best-effort queues have descriptors outstanding. We do not actually want an enforced delay between packets on best- effort queues, so we set the pace value to a reserved value that actually results in a delay of 0.

2011-02-15sfc: Distinguish queue lookup from test for queue existenceBen Hutchings
efx_channel_get_{rx,tx}_queue() currently return NULL if the channel isn't used for traffic in that direction. In most cases this is a bug, but some callers rely on it as an existence test. Add existence test functions efx_channel_has_{rx_queue,tx_queues}() and use them as appropriate. Change efx_channel_get_{rx,tx}_queue() to assert that the requested queue exists. Remove now-redundant initialisation from efx_set_channels(). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2011-02-15sfc: Move TX queue core queue mapping into tx.cBen Hutchings
efx_hard_start_xmit() needs to implement a mapping which is the inverse of tx_queue::core_txq. Move the initialisation of tx_queue::core_txq next to efx_hard_start_xmit() to make the connection more obvious. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2011-02-14can: c_can: Added support for Bosch C_CAN controllerBhupesh Sharma
Bosch C_CAN controller is a full-CAN implementation which is compliant to CAN protocol version 2.0 part A and B. Bosch C_CAN user manual can be obtained from: http://www.semiconductors.bosch.de/media/en/pdf/ipmodules_1/c_can/users_manual_c_can.pdf This patch adds the support for this controller. The following are the design choices made while writing the controller driver: 1. Interface Register set IF1 has be used only in the current design. 2. Out of the 32 Message objects available, 16 are kept aside for RX purposes and the rest for TX purposes. 3. NAPI implementation is such that both the TX and RX paths function in polling mode.
