Salil Mehta says: ==================== Support of Flow Director in HNS3 Ethernet Driver for HiP08 Rev2 SoC This patch-set adds the support of FD(Flow Director) in the HNS3 PF driver for HiP08 Rev2(0x21) SoC of Hisilicon. FD can be used in filtering the flows and deciding to drop the flow or forward it to paricular queue. Configuration consists of rules with input keys and actions. The rules are stored in TCAM. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

This patch adds support for add and delete rule by ethtool commands. HNS3 driver supports several flow types, include ETHER_FLOW, IP_USER_FLOW, TCP_V4_FLOW, UDP_V4_FLOW, SCTP_V4_FLOW, IPV6_USER_FLOW, TCP_V6_FLOW, UDP_V6_FLOW and SCTP_V6_FLOW. Signed-off-by:

Each flow director rule consists of input key and action. The input key is the condition for matching, includes tuples of L2/L3/L4 header. Action is the behaviour when a packet matches with the input key, such as drop the packet, or forward to a specified queue. The input key is stored in the tcam blocks, Each bit of input key can be masked. Signed-off-by:

Andrew Lunn says: ==================== Continue towards using linkmode in phylib These patches contain some further cleanup and helpers, and the first real patch towards using linkmode bitmaps in phylink. The macro magic in the RFC version has been replaced with run time initialisation. ==================== Signed-off-by: -
Andrew Lunn authored
This is one step in allowing phylib to make use of link_mode bitmaps, instead of u32 for supported and advertised features. Convert the phy drivers to use bitmaps to indicates the features they support. Build bitmap equivalents of the u32 values at runtime, and have the drivers point to the appropriate bitmap. These bitmaps are shared, and we don't want a driver to modify them. So mark them __ro_after_init. Within phylib, the features bitmap is currently turned back into a u32. This will be removed once the whole of phylib, and the drivers are converted to use bitmaps. Signed-off-by:

The macro PHY_GBIT_FEAUTRES needs to change into a bitmap in order to support link_modes. Remove its use from xgde by replacing it with its definition. Probably, the current behavior is wrong. It probably should be ANDing not assigning. Signed-off-by:

The phy_mii_ioctl can be used to write a value into the MII_ADVERTISE register in the PHY. Since this changes the state of the PHY, we need to make the same change to phydev->advertising. Add a helper which can convert the register value to a linkmode. Signed-off-by:

When SKBs are coalesced, we can have SKBs with different frag sizes. Some with PAGE_SIZE and some not with PAGE_SIZE. Since recv_skip_hint is always set to the full SKB size, it can overestimate the amount that should be read using normal read for coalesced packets. Change the recv_skip_hint so that it only includes the first frags that are not of PAGE_SIZE. Signed-off-by:

Previously receiver buffer auto-tuning starts after receiving one advertised window amount of data. After the initial receiver buffer was raised by patch a337531b ("tcp: up initial rmem to 128KB and SYN rwin to around 64KB"), the reciver buffer may take too long to start raising. To address this issue, this patch lowers the initial bytes expected to receive roughly the expected sender's initial window.

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2018-10-01 This series contains updates to ice driver only. Anirudh provides several changes to "prep" the driver for upcoming features. Specifically, the functions that are used for PF VSI/netdev setup will also be used in SR-IOV support and to allow the reuse of these functions, code needs to move. Dave provides the only other change in the series, updates the driver to protect the reset patch in its entirety. This is done by adding the various bit checks to determine if a reset is scheduled/initiated and whether it came from the software or firmware. ==================== Signed-off-by: -
Dave Ertman authored
Currently, there is no bit, or set of bits, that protect the entirety of the reset path. If the reset is originated by the driver, then the relevant one of the following bits will be set when the reset is scheduled: __ICE_PFR_REQ __ICE_CORER_REQ __ICE_GLOBR_REQ This bit will not be cleared until after the rebuild has completed. If the reset is originated by the FW, then the first the driver knows of it will be the reception of the OICR interrupt. The __ICE_RESET_OICR_RECV bit will be set in the interrupt handler. This will also be the indicator in a SW originated reset that we have completed the pre-OICR tasks and have informed the FW that a reset was requested. To utilize these bits, change the function: ice_is_reset_recovery_pending() to be: ice_is_reset_in_progress() The new function will check all of the above bits in the pf->state and will return a true if one or more of these bits are set.

The functions that are used for PF VSI/netdev setup will also be used for SR-IOV support. To allow reuse of these functions, move these functions out of ice_main.c to ice_common.c/ice_lib.c This move is done across multiple patches. Each patch moves a few functions and may have minor adjustments. For example, a function that was previously static in ice_main.c will be made non-static temporarily in its new location to allow the driver to build cleanly. These adjustments will be removed in subsequent patches where more code is moved out of ice_main.c In this particular patch, the following functions were moved out of ice_main.c: int ice_add_mac_to_list ice_free_fltr_list ice_stat_update40 ice_stat_update32 ice_update_eth_stats ice_vsi_add_vlan ice_vsi_kill_vlan ice_vsi_manage_vlan_insertion ice_vsi_manage_vlan_stripping Signed-off-by:

Gavi Teitz authored
Increased the amount of channels the representors can open to be the amount of CPUs. The default amount opened remains one. Used the standard NIC netdev functions to: * Set RSS params when building the representors' params. * Setup an indirect TIR and RQT for the representors upon initialization. * Create a TTC flow table for the representors' indirect TIR (when creating the TTC table, mlx5e_set_ttc_basic_params() is not called, in order to avoid setting the inner_ttc param, which is not needed). Added ethtool control to the representors for setting and querying the amount of open channels. Additionally, included logic in the representors' ethtool set channels handler which controls a representor's vport rx rule, so that if there is one open channel the rx rule steers traffic to the representor's direct TIR, whereas if there is more than one channel, the rx rule steers traffic to the new TTC flow table.
