* sfc: Move siena_reset_hw() and siena_map_reset_reason() into MCDI moduleBen Hutchings2013-08-21
| | | | | | | These implementations should work for EF10 too. Rename them accordingly. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

* sfc: Ensure MCDI buffers, but not lengths, are dword alignedBen Hutchings2013-08-21
| | | | | | | | | | | | | | | We currently require that MCDI request and response lengths are multiples of 4 bytes, because we will copy dwords in and out of shared memory and we want to be sure we won't read or write out of bounds. But all we really need to know is that there is sufficient padding for that. Also, we should ensure that buffers are dword-aligned, as on some architectures misaligned access will result in data corruption or a crash. Change the buffer type to array-of-efx_dword_t and remove the requirement that the lengths are multiples of 4. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
* sfc: Use proper macros to declare and access MCDI arraysBen Hutchings2013-08-21
| | | | | | | | | | | | | A few functions are using heap buffers; change them to use stack buffers as we really don't need to resort to the heap for a 252 byte buffer in process context. MC_CMD_MEMCPY is quite weird in that it can use inline data placed in the request buffer after the array of records. Thus there are two variable-length arrays and we can't use the normal accessors for the second. So we have to use _MCDI_PTR() in efx_sriov_memcpy().

* sfc: Fill out the set of MCDI accessorsBen Hutchings2013-08-21
| | | | | | | | | | | | | | | We need to access arrays of 16-bit words and 32-bit dwords in MCDI buffers based on the MCDI protocol definitions. We should also be able to read and write fields within structures, without specifying an array index each time. So add MCDI_FIELD() and make MCDI_ARRAY_FIELD() use it. Also add MCDI_SET_FIELD(). Split MCDI_ARRAY_PTR() into MCDI_ARRAY_STRUCT_PTR() and _MCDI_ARRAY_PTR(), which are currently identical but will diverge in later changes. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
* sfc: Rationalise MCDI buffer accessorsBen Hutchings2013-08-21
| | | | | | | | | | | | Add _MCDI_DWORD() which yields an lvalue for the given dword field and change MCDI_DWORD(), MCDI_SET_DWORD() and MCDI_QWORD() to use it. Fold the rather trivial MCDI_PTR2() into MCDI_PTR() and _MCDI_DWORD(). Remove MCDI_SET_DWORD2() and MCDI_QWORD2(). MCDI_DWORD2() should also go, but it still has one user which we'll get rid of later. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

| * net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changesMoshe Lazer2013-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the previous QUERY_PAGES command version we used one command to get the required amount of boot, init and post init pages. The new version uses the op_mod field to specify whether the query is for the required amount of boot, init or post init pages. In addition the output field size for the required amount of pages increased from 16 to 32 bits. In MANAGE_PAGES command the input_num_entries and output_num_entries fields sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10. In the pages request event the num_pages field also changed to 32 bits. In the HCA-capabilities-layout the size and location of max_qp_mcg field has been changed to support 24 bits. This patch isn't compatible with firmware versions < 5; however, it turns out that the first GA firmware we will publish will not support previous versions so this should be OK.

These bits must not be set however when eTSEC is operated in Half-Duplex mode. Unfortunately, the driver currently sets these bits unconditionally. This patch adds the proper handling of the PAUSE frame capability register bits by implementing the ethtool -A interface. When pause autoneg is enabled, the controller uses the phy's capability to negotiate PAUSE frame settings with the link partner and reconfigures its Rx_Flow and Tx_Flow settings to match the capabilities of the link partner. If pause autoneg is off, the PAUSE frame generation may be forced manually (ethtool -A). Flow control is disabled by default now. This implementation is inspired by the tg3 driver.

* | | netxen: clean up unnecessary MSI/MSI-X capability findYijing Wang2013-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PCI core will initialize device MSI/MSI-X capability in pci_msi_init_pci_dev(). So device driver should use pci_dev->msi_cap/msix_cap to determine whether the device support MSI/MSI-X instead of using pci_find_capability(pci_dev, PCI_CAP_ID_MSI/MSIX). Access to PCIe device config space again will consume more time.
