* bnx2x: Changing the Disabled state to a flagEilon Greenstein2009-10-15
| | | | | | | | | | When working with DCC, a function can be disabled or enabled (virtual link down or up). Using the function state introduced some race conditions with the load/unload flow. Using a separate flag to indicate that the function is disabled. Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* bnx2x: Remove the init_dmae field from bpEilon Greenstein2009-08-13
| | | | | | | | | | | | | Moved the dmae_command from the heap to the stack. This will save 56 bytes per bnx2x structure. As a side benefit, we can also reduce the time the dmae_mutex is held. This is because do we not need to hold this mutex when setting up the dmae command. The memory where is dmae command is stored is not a shared resource and doesn not need to be protected.

* bnx2x: Configurable pause schemeEilon Greenstein2009-08-13
| | | | | | | | | | | | When a given ring is running out of space, the FW can send pause towards the network. When working with multi-queues, when one queue is getting out of space it can block all other queues. The preferred scheme is to send pause frames only when running out of the shared internal chip buffers and if a given queue cannot place a packet on the host, it will drop it. Since some users might want to work in drop-less mode, allowing changing the behavior as a module parameter. Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

* bnx2x: Using the new FWEilon Greenstein2009-08-13
| | | | | | | | | | | | | | | The new FW improves the packets per second rate. It required a lot of change in the FW which implies many changes in the driver to support it. It is now also possible for the driver to use a separate MSI-X vector for Rx and Tx - this also add some to the complicity of this change. All things said - after this patch, practically all performance matrixes show improvement. Though Vladislav Zolotarov is not signed on this patch, he did most of the job and deserves credit for that.

* bnx2x: Supporting BCM8727 PHYEilon Greenstein2009-07-21
| | | | | | | | | | | | | Adding support for BCM8727 - a dual port SFP+ PHY. That includes verification of the optic module vendor and part number - the list of approved modules resides on the nvram and the module is verified by the FW. Since not all users would like to use this verification feature, it can be disabled. The default behavior is to issue a warning if the module is not approved, but still allow using it - but it is also possible to disable the link if the module is not approved.

* bnx2x: Separated FW from the source.Vladislav Zolotarov2009-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | >From now on FW will be downloaded from the binary file using request_firmware. There will be different files for every supported chip. Currently 57710 (e1) and 57711 (e1h). File names have the following format: bnx2x-<chip version>-<FW version>.fw. ihex versions of current FW files are submitted in the next patch. Each binary file has a header in the following format: struct bnx2x_fw_file_section { __be32 len; __be32 offset; } struct bnx2x_fw_file_hdr { struct bnx2x_fw_file_section init_ops; struct bnx2x_fw_file_section init_ops_offsets; struct bnx2x_fw_file_section init_data; struct bnx2x_fw_file_section tsem_int_table_data; struct bnx2x_fw_file_section tsem_pram_data; struct bnx2x_fw_file_section usem_int_table_data; struct bnx2x_fw_file_section usem_pram_data; struct bnx2x_fw_file_section csem_int_table_data; struct bnx2x_fw_file_section csem_pram_data; struct bnx2x_fw_file_section xsem_int_table_data; struct bnx2x_fw_file_section xsem_pram_data; struct bnx2x_fw_file_section fw_version; } Each bnx2x_fw_file_section contains the length and the offset of the appropriate section in the binary file. Values are stored in the big endian format. Data types of arrays: init_data __be32 init_ops_offsets __be16 XXsem_pram_data u8 XXsem_int_table_data u8 init_ops struct raw_op { u8 op; __be24 offset; __be32 data; } fw_version u8 >From now boundaries of a specific initialization stage are stored in init_ops_offsets array instead of being defined by separate macroes. The index in init_ops_offsets is calculated by BLOCK_OPS_IDX macro: #define BLOCK_OPS_IDX(block, stage, end) \ (2*(((block)*STAGE_IDX_MAX) + (stage)) + (end)) Security: In addition to sanity check of array boundaries bnx2x will check a FW version.

If the packet was actually using the buffer up to its limit and if the last 64 bytes of the buffer crossed 4KB boundary then an unmapped PCI page was accessed. The fix is to use only one parameter for the buffer size - there is no need to differentiate between the buffer size and the PCI mapping size since the extra 64 bytes can actually be used by the FW to align the Ethernet payload to 64 bytes.
