Tony Nguyen says: ==================== 40GbE Intel Wired LAN Driver Updates 2021-02-10 This series contains updates to i40e driver only. Arkadiusz adds support for software controlled DCB. Upon disabling of the firmware LLDP agent, the driver configures DCB with default values (only one Traffic Class). At the same time, it allows a software based LLDP agent - userspace application i.e. lldpad) to receive DCB TLVs and set desired DCB configuration through DCB related netlink callbacks. Aleksandr implements get and set ethtool ops for Energy Efficient Ethernet. Przemyslaw extends support for ntuple filters allowing for Flow Director IPv6 and VLAN filters. Kaixu Xia removes an unneeded assignment. ==================== Signed-off-by:

The changes to make rxrpc create the udp socket missed a bit to add the Kconfig dependency on the udp tunnel code to do this. Fix this by adding making AF_RXRPC select NET_UDP_TUNNEL. Fixes: 1a9b86c9 ("rxrpc: use udp tunnel APIs instead of open code in rxrpc_open_socket") Reported-by:

Hariprasad Kelam says: ==================== ethtool support for fec and link configuration This series of patches add support for forward error correction(fec) and physical link configuration. Patches 1&2 adds necessary mbox handlers for fec mode configuration request and to fetch stats. Patch 3 registers driver callbacks for fec mode configuration and display. Patch 4&5 adds support of mbox handlers for configuring link parameters like speed/duplex and autoneg etc. Patche 6&7 registers driver callbacks for physical link configuration. Change-log: v2: - Fixed review comments - Corrected indentation issues - Return -ENOMEM incase of mbox allocation failure - added validation for input fecparams bitmask values - added more comments V3: - Removed inline functions - Make use of ethtool helpers APIs to display supported advertised modes - corrected indentation issues - code changes such that return early in case of failure to aid branch prediction v4: - Corrected indentation issues - Use FEC_OFF if user requests for FEC_AUTO mode - Do not clear fec stats in case of user changes fec mode - dont hide fec stats depending on interface mode selection ==================== Signed-off-by: -

This patch adds support to fetch fec stats from PHY. The stats are put in the shared data struct fwdata. A PHY driver indicates that it has FEC stats by setting the flag fwdata.phy.misc.has_fec_stats Besides CGX_CMD_GET_PHY_FEC_STATS, also add CGX_CMD_PRBS and CGX_CMD_DISPLAY_EYE to enum cgx_cmd_id so that Linux's enum list is in sync with firmware's enum list.

Pavel pointed that the return of dma_addr_t in otx2_alloc_rbuf/__otx2_alloc_rbuf() seem suspicious because a negative error code may be returned in some cases. For a dma_addr_t, the error code such as -ENOMEM does seem a valid value, so we can't judge if the buffer allocation fail or not based on that value. Add a parameter for otx2_alloc_rbuf/__otx2_alloc_rbuf() to store the dma address and make the return value to indicate if the buffer allocation really fail or not. Reported-by:

MBIM has initially been specified by USB-IF for transporting data (IP) between a modem and a host over USB. However some modern modems also support MBIM over PCIe (via MHI). In the same way as QMAP(rmnet), it allows to aggregate IP packets and to perform context multiplexing. This change adds minimal MBIM data transport support to MHI, allowing to support MBIM only modems. MBIM being based on USB NCM, it reuses and copy some helpers/functions from the USB stack (cdc-ncm, cdc-mbim). Note that is a subset of the CDC-MBIM specification, supporting only transport of network data (IP), there is no support for DSS. Moreover the multi-session (for multi-pdn) is not supported in this initial version, but will be added latter, and aligned with the cdc-mbim solution (VLAN tags). This code has been inspired from the mhi_mbim downstream implementation (Carl Yin <carl.yin@quectel.com>). Signed-off-by:

MHI can transport different protocols, some are handled at upper level, like IP and QMAP(rmnet/netlink), but others will need to be inside MHI net driver, like mbim. This change adds support for protocol rx and tx_fixup callbacks registration, that can be used to encode/decode the targeted protocol. Signed-off-by:

Flow director for IPv6 is not supported. 1) Implementation of support for IPv6 flow director. 2) Added handlers for addition of TCP6, UDP6, SCTP6, IPv6. 3) Refactored legacy code to make it more generic. 4) Added packet templates for TCP6, UDP6, SCTP6, IPv6. 5) Added handling of IPv6 source and destination address for flow director. 6) Improved argument passing for source and destination portin TCP6, UDP6 and SCTP6. 7) Added handling of ethtool -n for IPv6, TCP6,UDP6, SCTP6. 8) Used correct bit flag regarding FLEXOFF field of flow director data descriptor. Without this patch, there would be no support for flow director on IPv6, TCP6, UDP6, SCTP6.

If LLDP agent is turned off in BIOS, or after setting private flag ("disable-fw-lldp on"). The driver initialized DCB functionality with default values, one traffic class with 100% bandwidth allocated.
