qed_nvmetcp_ip_services.c and its corresponding header file were introduced in commit 806ee7f81a2b ("qed: Add IP services APIs support") but there's still no users for any of the functions they declare.

2021-12-04qed*: esl priv flag support through ethtoolManish Chopra1-0/+3
ESL(Enhanced System Lockdown) was designed to lock PCI adapter firmware images and prevent changes to critical non-volatile configuration data so that uncontrolled, malicious or unintentional modification to the adapters are avoided, ensuring it's operational state. Once this feature is enabled, the device is locked, rejecting any modification to non-volatile images. Once unlocked, the protection is off such that firmware and non-volatile configurations may be altered. Driver just reflects the capability and status of this through the ethtool private flag.

2021-10-14ethernet: constify references to netdev->dev_addr in driversJakub Kicinski3-3/+4
This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

2020-10-16Merge branch 'dynamic_sg' into rdma.git for-nextJason Gunthorpe1-0/+1
From Maor Gottlieb says: ==================== This series extends __sg_alloc_table_from_pages to allow chaining of new pages to an already initialized SG table. This allows for drivers to utilize the optimization of merging contiguous pages without a need to pre allocate all the pages and hold them in a very large temporary buffer prior to the call to SG table initialization. The last patch changes the Infiniband core to use the new API. It removes duplicate functionality from the code and benefits from the optimization of allocating dynamic SG table from pages. In huge pages system of 2MB page size, without this change, the SG table would contain x512 SG entries. ==================== * branch 'dynamic_sg': RDMA/umem: Move to allocate SG table from pages lib/scatterlist: Add support in dynamic allocation of SG table from pages tools/testing/scatterlist: Show errors in human readable form tools/testing/scatterlist: Rejuvenate bit-rotten test

2020-07-23qed: simplify chain allocation with init params structAlexander Lobakin2-14/+16
To simplify qed_chain_alloc() prototype and call sites, introduce struct qed_chain_init_params to specify chain params, and pass a pointer to filled struct to the actual qed_chain_alloc() instead of a long list of separate arguments.

2020-07-23qed: move chain initialization inlines next to allocation functionsAlexander Lobakin1-112/+0
qed_chain_init*() are used in one file/place on "cold" path only, so they can be uninlined and moved next to the call sites.

2020-07-23qed: sanitize PBL chains allocationAlexander Lobakin1-8/+8
PBL chain elements are actually DMA addresses stored in __le64, but currently their size is hardcoded to 8, and DMA addresses are assigned via cast to variable-sized dma_addr_t without any bitwise conversions. Change the type of pbl_virt array to match the actual one, add a new field to store the size of allocated DMA memory and sanitize elements assignment. Misc: give more logic names to the members of qed_chain::pbl_sp embedded struct.

2020-07-21qed: add support for the extended speed and FEC modesAlexander Lobakin1-0/+1
Add all necessary code (NVM parsing, MFW and Ethtool reports etc.) to support extended speed and FEC modes. These new modes are supported by the new boards revisions and newer MFW versions. Misc: correct port type for MEDIA_KR. Signed-off-by: Alexander Lobakin <alobakin@marvell.com> Signed-off-by: Igor Russkikh <irusskikh@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-07-21qed, qede, qedf: convert link mode from u32 to ETHTOOL_LINK_MODEAlexander Lobakin1-41/+6
Currently qed driver already ran out of 32 bits to store link modes, and this doesn't allow to add and support more speeds. Convert custom link mode to generic Ethtool bitmap and definitions (convenient Phylink shorthands are used for elegance and readability). This allowed us to drop all conversions/mappings between the driver and Ethtool. This involves changes in qede and qedf as well, as they used definitions from shared "qed_if.h".

2020-07-06net: qed: sanitize BE/LE data processingAlexander Lobakin1-8/+7
Current code assumes that both host and device operates in Little Endian in lots of places. While this is true for x86 platform, this doesn't mean we should not care about this. This commit addresses all parts of the code that were pointed out by sparse checker. All operations with restricted (__be*/__le*) types are now protected with explicit from/to CPU conversions, even if they're noops on common setups. I'm sure there are more such places, but this implies a deeper code investigation, and is a subject for future works.
