2013-08-29sfc: Remove unnecessary use of atomic_tBen Hutchings2-17/+13
We can set, get and compare-and-exchange without using atomic_t. Change efx_mcdi_iface::state to the enum type we really wanted it to be. Suggested-by: David Miller <[email protected]> Signed-off-by: Ben Hutchings <[email protected]>

2013-08-29sfc: Add support for new board sensorsBen Hutchings1-30/+91
Add support for power and current sensors, which need to be named differently in sysfs. Power sensors also require values to be scaled between MCDI and sysfs, and have no minimum value. Add definitions of the power, current, fan, and additional temperature and voltage sensors found on SFA6902F, SFN7022F and SFN7122F. (Includes a bug fix from Andrew Jackson.)

We were transversing the tx_ring with IXGBE_NUM_RX_QUEUES. Now this define happens to have the correct value but this is misleading and a change later could easily make this no longer true.

2013-08-29qlcnic: underflow in qlcnic_validate_max_tx_rings()Dan Carpenter2-2/+2
This function checks the upper bound but it doesn't check for negative numbers: if (txq > QLCNIC_MAX_TX_RINGS) { I've solved this by making "txq" a u32 type. I chose that because ->tx_count in the ethtool_channels struct is a __u32. This bug was added in aa4a1f7df7 ('qlcnic: Enable Tx queue changes using ethtool for 82xx Series adapter.').

2013-08-27bnx2x: Fix move FP memory deallocationsYuval Mintz1-0/+6
If driver will fail to allocate all queues, it will shrink the number of queues and move the storage queue to its correct place (i.e., the last queue among the newly supported number). When changing the pointers of the new location of the FCoE queue, we need to pay special attention to the aggregations pointer - that memory is allocated during probe and released upon driver removal. Current implementation has 2 pointers pointing to the same chunk of allocated memory, meaning upon removal there will be two kfree() of the same chunk while the other won't be released.

efx_reset_up() calls efx_nic_type::reconfigure_mac once directly, then again through efx_start_all() -> efx_start_port() -> efx->type->reconfigure_mac(). This first call is also made too early to work properly on EF10. Signed-off-by: Ben Hutchings <[email protected]>
2013-08-27sfc: use MCDI epoch flag to improve MC reboot detection in the driverDaniel Pieczko2-6/+15
The Huntington MC will reject all MCDI requests after an MC reboot until it sees one with the NOT_EPOCH flag clear. This flag is set by default for all requests, and then cleared on the first request after we detect that an MC reboot has occurred. The old MCDI_STATUS_DELAY_COUNT gave a timeout of 10ms, which was not long enough for the driver to detect that a reboot had occurred based on the warm boot count while calling efx_mcdi_poll_reboot() from the loop in efx_mcdi_ev_death().

2013-08-27sfc: Delegate MAC/NIC statistic description to efx_nic_typeBen Hutchings8-389/+498
Various hardware statistics that are available for Siena are unavailable or meaningless for Falcon. Huntington adds further to the NIC-type-specific statistics, as it has different MAC blocks from Falcon/Siena. All NIC types still provide most statistics by DMA, and use little-endian byte order. Therefore: 1. Add some general utility functions for reporting hardware statistics, efx_nic_describe_stats() and efx_nic_update_stats(). 2. Add an efx_nic_type::describe_stats operation to get the number and names of statistics, implemented using efx_nic_describe_stats() 3. Change efx_nic_type::update_stats to store the core statistics (struct rtnl_link_stats64) or full statistics (array of u64) in a caller-provided buffer. Use efx_nic_update_stats() to aid in the implementation. 4. Rename struct efx_ethtool_stat to struct efx_sw_stat_desc and EFX_ETHTOOL_NUM_STATS to EFX_ETHTOOL_SW_STAT_COUNT. 5. Remove efx_nic::mac_stats and struct efx_mac_stats. Signed-off-by: Ben Hutchings <[email protected]>

2013-08-27sfc: Move MTD operations into efx_nic_typeBen Hutchings9-831/+807
Merge the per-NIC-type MTD probe selection and struct efx_mtd_ops into struct efx_nic_type. Move the implementations into the appropriate source files. Several NVRAM functions are now only called from MTD operations which are now implemented in the same file (falcon.c or mcdi.c). There is no need for them to be extern, or to be defined at all if CONFIG_SFC_MTD is not enabled, so move them into the #ifdef CONFIG_SFC_MTD sections in those files. Most of the SPI-related definitions are also only used in falcon.c, so move them there. Put the remainder of spi.h into nic.h (which previously included it).

2013-08-27be2net: Fix be_cmd_if_create() to use MBOX if MCCQ is not createdSathya Perla1-24/+85
Currently the IF_CREATE FW cmd is issued only *after* MCCQ is created as it was coded to only use MCCQ. By fixing this, cmd_if_create() can be called before MCCQ is created and the same routine for VF provisioning can be called after. This allows for consolidating all the queue create routines by moving the be_cmd_if_create() call above all queue create calls in be_setup().
