2011-02-18ath5k: Correct channel setting for AR2317 chipNikolay Ledovskikh1-0/+1
Correct channel setting function must be used for AR2317. When I tested ahb patch on bullet2 all seemed to work fine, but it couldn't connect another host (using ibss for example). During an analysis I observed that it's transmitting on another channel. I looked into madwifi code and understood that the problem is in channel setting function. So atheros RF2317 not fully handled in the current ath5k version and must be patched.

2011-02-17enic: Always use single transmit and single receive hardware queues per deviceVasanthy Kolluri2-4/+4
We believe that our earlier patch for supporting multiple hardware receive queues per enic device requires more internal testing. At this point, we think that it's best to disable the use of multiple receive queues. The current patch provides an effective means for the same. Also, we continue to disallow multiple hardware transmit queues per device. But change the way we enforce this in order to maintain consistency with the way receive queues are handled.

2011-02-17tg3: Restrict phy ioctl accessMatt Carlson1-2/+6
If management firmware is present and the device is down, the firmware will assume control of the phy. If a phy access were allowed from the host, it will collide with firmware phy accesses, resulting in unpredictable behavior. This patch fixes the problem by disallowing phy accesses during the problematic condition.

Without calling of netif_carrier_off at the end of the probe the operstate is unknown when the device is initially opened. By default the carrier is on so when the device is opened and netif_carrier_on is called the link watch event is not fired and operstate remains zero (unknown).

We don't actually need this and it causes problems for internal use of this functionality. Currently there is a single use of the FILE * pointer. That is the serial core which uses it to check tty_hung_up_p. However if that is true then IO_ERROR is also already set so the check may be removed.

2011-02-17ixgbe: fix panic due to uninitialised pointerAndy Gospodarek1-2/+4
Systems containing an 82599EB and running a backported driver from upstream were panicing on boot. It turns out hw->mac.ops.setup_sfp is only set for 82599, so one should check to be sure that pointer is set before continuing in ixgbe_sfp_config_module_task. I verified by inspection that the upstream driver has the same issue and also added a check before the call in ixgbe_sfp_link_config.

2011-02-17e1000e: flush all writebacks before unloadJesse Brandeburg1-10/+21
The driver was not flushing all writebacks before unloading, possibly causing memory to be written by the hardware after the driver had reinitialized the rings.

2011-02-15sfc: Add TX queues for high-priority trafficBen Hutchings7-28/+156
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 Hutchings3-29/+33
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 <[email protected]>
2011-02-15sfc: Move TX queue core queue mapping into tx.cBen Hutchings3-4/+10
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 <[email protected]>
