2020-05-28net: ks8851: Remove ks8851_mll.cMarek Vasut
The ks8851_mll.c is replaced by ks8851_par.c, which is using common code from ks8851.c, just like ks8851_spi.c . Remove this old ad-hoc driver. Signed-off-by: Marek Vasut <marex@denx.de> Cc: David S.

2020-05-28net: ks8851: Implement Parallel bus operationsMarek Vasut
Implement accessors for KS8851-16MLL/MLLI/MLLU parallel bus variant of the KS8851. This is based off the ks8851_mll.c , which is a driver for exactly the same hardware, however the ks8851.c code is much higher quality. Hence, this patch pulls out the relevant information from the ks8851_mll.c on how to access the bus, but uses the common ks8851.c code. To make this patch reviewable, instead of rewriting ks8851_mll.c, ks8851_mll.c is removed in a separate subsequent patch. Signed-off-by: Marek Vasut <marex@denx.de> Cc: David S.

Pull all the SPI bus specific code into a separate file, so that it is not mixed with the common code. Rename ks8851.c to ks8851_common.c.

The ks8851_rdreg32() is used only in one place, to read two registers using a single read. To make it easier to support 16-bit accesses via parallel bus later on, replace this single read with two 16-bit reads from each of the registers and drop the ks8851_rdreg32() altogether. If this has noticeable performance impact on the SPI variant of KS8851, then we should consider using regmap to abstract the SPI and parallel bus options and in case of SPI, permit regmap to merge register reads of neighboring registers into single, longer, read.

2020-05-28Merge branch 'vmxnet3-upgrade-to-version-4'David S. Miller
Ronak Doshi says: ==================== vmxnet3: upgrade to version 4 vmxnet3 emulation has recently added several new features which includes offload support for tunnel packets, support for new commands the driver can issue to emulation, change in descriptor fields, etc. This patch series extends the vmxnet3 driver to leverage these new features. Compatibility is maintained using existing vmxnet3 versioning mechanism as follows: - new features added to vmxnet3 emulation are associated with new vmxnet3 version viz. vmxnet3 version 4. - emulation advertises all the versions it supports to the driver. - during initialization, vmxnet3 driver picks the highest version number supported by both the emulation and the driver and configures emulation to run at that version. In particular, following changes are introduced: Patch 1: This patch introduces utility macros for vmxnet3 version 4 comparison and updates Copyright information. Patch 2: This patch implements get_rss_hash_opts and set_rss_hash_opts methods to allow querying and configuring different Rx flow hash configurations which can be used to support UDP/ESP RSS. Patch 3: This patch introduces segmentation and checksum offload support for encapsulated packets. This avoids segmenting and calculating checksum for each segment and hence gives performance boost. Patch 4: With all vmxnet3 version 4 changes incorporated in the vmxnet3 driver, with this patch, the driver can configure emulation to run at vmxnet3 version 4. Changes in v3 -> v4: - Replaced BUG_ON() with WARN_ON_ONCE() Changes in v2 -> v3: - fixed get_rss_hash_opts to return correct values for udp rss Changes in v2: - Fixed compilation issue due to missing closed brace - added fallthrough comment ==================== Signed-off-by: David S.

2020-05-28vmxnet3: add geneve and vxlan tunnel offload supportRonak Doshi
Vmxnet3 version 3 device supports checksum/TSO offload. Thus, vNIC to pNIC traffic can leverage hardware checksum/TSO offloads. However, vmxnet3 does not support checksum/TSO offload for Geneve/VXLAN encapsulated packets. Thus, for a vNIC configured with an overlay, the guest stack must first segment the inner packet, compute the inner checksum for each segment and encapsulate each segment before transmitting the packet via the vNIC. This results in significant performance penalty. This patch will enhance vmxnet3 to support Geneve/VXLAN TSO as well as checksum offload.

Jesse fixes a number of issues, starting with fixing the remaining signed versus unsigned comparison issues. Cleaned up an unused code define. Fixed the implementation of the manage MAC write command, to simplify it by using a simple array to represent the MAC address when writing it. Paul fixes the setting of the VF default LAN address, by removing a check that assumed that the address had been deleted and zeroed. Surabhi prevents a memory leak on filter management initialization failures and during queue initialization and buffer allocation failures. Brett adds additional receive error counters that are reported by ethtool. Fixed the enabling and disabling of VLAN stripping when the PVID has been set. Evan fixes a race condition between the firmware and software, which can occur between the admin queue setup and the first command sent. Marta fixes the driver when XDP transmit rings are destroyed, also make sure the XDP transmit queues are also destroyed. Update the statistics when XDP transmit programs are loaded and packets are sent. Changed the number of XDP transmit queues to match the number of receive queues, instead of matching the number of transmit queues. Bruce avoids undefined behavior by not writing the 8-bit element init_q_state with the associated internal-to-hardware field which is 122-bits. Anirudh (Ani) refactors the receive checksum checks.

In some cases these functions seem pretty heavy handed as they do a lock_sock even for just setting a single variable, but this mirrors the real setsockopt implementation unlike a few drivers that just set set the fields directly. Changes since v2: - drop the separately merged kernel_getopt_removal - drop the sctp patches, as there is conflicting cleanup going on - add an additional ACK for the rxrpc changes Changes since v1: - use ->getname for sctp sockets in dlm - add a new ->bind_add struct proto method for dlm/sctp - switch the ipv6 and remaining sctp helpers to inline function so that the ipv6 and sctp modules are not pulled in by any module that could potentially use ipv6 or sctp connections - remove arguments to various sock_* helpers that are always used with the same constant arguments ==================== Signed-off-by: David S.
